While we currently have the `GIT_CONFIG_PARAMETERS` environment variable
which can be used to pass runtime configuration data to git processes,
it's an internal implementation detail and not supposed to be used by
end users.
Next to being for internal use only, this way of passing config entries
has a major downside: the config keys need to be parsed as they contain
both key and value in a single variable. As such, it is left to the user
to escape any potentially harmful characters in the value, which is
quite hard to do if values are controlled by a third party.
This commit thus adds a new way of adding config entries via the
environment which gets rid of this shortcoming. If the user passes the
`GIT_CONFIG_COUNT=$n` environment variable, Git will parse environment
variable pairs `GIT_CONFIG_KEY_$i` and `GIT_CONFIG_VALUE_$i` for each
`i` in `[0,n)`.
While the same can be achieved with `git -c <name>=<value>`, one may
wish to not do so for potentially sensitive information. E.g. if one
wants to set `http.extraHeader` to contain an authentication token,
doing so via `-c` would trivially leak those credentials via e.g. ps(1),
which typically also shows command arguments.

The `getenv_safe()` helper function helps to safely retrieve multiple
environment values without the need to depend on platform-specific
behaviour for the return value's lifetime. We'll make use of this
function in a following patch, so let's make it available by making it
non-static and adding a declaration.

The previous commit added a new format for $GIT_CONFIG_PARAMETERS which
is able to robustly handle subsections with "=" in them. Let's start
writing the new format. Unfortunately, this does much less than you'd
hope, because "git -c" itself has the same ambiguity problem! But it's
still worth doing:
- we've now pushed the problem from the inter-process communication
into the "-c" command-line parser. This would free us up to later
add an unambiguous format there (e.g., separate arguments like "git
--config key value", etc).
- for --config-env, the parser already disallows "=" in the
environment variable name. So:
git --config-env section.with=equals.key=ENVVAR
will robustly set section.with=equals.key to the contents of
$ENVVAR.
The new test shows the improvement for --config-env.

When we stuff config options into GIT_CONFIG_PARAMETERS, we shell-quote
each one as a single unit, like:
'section.one=value1' 'section.two=value2'
On the reading side, we de-quote to get the individual strings, and then
parse them by splitting on the first "=" we find. This format is
ambiguous, because an "=" may appear in a subsection. So the config
represented in a file by both:
[section "subsection=with=equals"]
key = value
and:
[section]
subsection = with=equals.key=value
ends up in this flattened format like:
'section.subsection=with=equals.key=value'
and we can't tell which was desired. We have traditionally resolved this
by taking the first "=" we see starting from the left, meaning that we
allowed arbitrary content in the value, but not in the subsection.
Let's make our environment format a bit more robust by separately
quoting the key and value. That turns those examples into:
'section.subsection=with=equals.key'='value'
and:
'section.subsection'='with=equals.key=value'
respectively, and we can tell the difference between them. We can detect
which format is in use for any given element of the list based on the
presence of the unquoted "=". That means we can continue to allow the
old format to work to support any callers which manually used the old
format, and we can even intermingle the two formats. The old format
wasn't documented, and nobody was supposed to be using it. But it's
likely that such callers exist in the wild, so it's nice if we can avoid
breaking them. Likewise, it may be possible to trigger an older version
of "git -c" that runs a script that calls into a newer version of "git
-c"; that new version would see the intermingled format.
This does create one complication, which is that the obvious format in
the new scheme for
[section]
some-bool
is:
'section.some-bool'
with no equals. We'd mistake that for an old-style variable. And it even
has the same meaning in the old style, but:
[section "with=equals"]
some-bool
does not. It would be:
'section.with=equals=some-bool'
which we'd take to mean:
[section]
with = equals=some-bool
in the old, ambiguous style. Likewise, we can't use:
'section.some-bool'=''
because that's ambiguous with an actual empty string. Instead, we'll
again use the shell-quoting to give us a hint, and use:
'section.some-bool'=
to show that we have no value.
Note that this commit just expands the reading side. We'll start writing
the new format via "git -c" in a future patch. In the meantime, the
existing "git -c" tests will make sure we didn't break reading the old
format. But we'll also add some explicit coverage of the two formats to
make sure we continue to handle the old one after we move the writing
side over.
And one final note: since we're now using the shell-quoting as a
semantically meaningful hint, this closes the door to us ever allowing
arbitrary shell quoting, like:
'a'shell'would'be'ok'with'this'.key=value
But we have never supported that (only what sq_quote() would produce),
and we are probably better off keeping things simple, robust, and
backwards-compatible, than trying to make it easier for humans. We'll
continue not to advertise the format of the variable to users, and
instead keep "git -c" as the recommended mechanism for setting config
(even if we are trying to be kind not to break users who may be relying
on the current undocumented format).

In the "git blame --porcelain" output, lines that ends with three
integers may not be the line that shows a commit object with line
numbers and block length (the contents from the blamed file or the
summary field can have a line that happens to match). Also, the
names of the author may have more than three SP separated tokens
("git blame -L242,+1 cf6de18aabf7 Documentation/SubmittingPatches"
gives an example). The existing "grep -E | cut" pipeline is a bit
too loose on these two points.
While they can be assumed on the test data, it is not so hard to
use the right pattern from the documented format, so let's do so.

We run "git pull" against "$cask_repo"; clarify that we are
expecting not to have any of our own modifications and running "git
pull" to merely update, by passing "--ff-only" on the command line.
Also, the "brew cask install" command line triggers an error message
that says:
Error: Calling brew cask install is disabled! Use brew install
[--cask] instead.
In addition, "brew install caskroom/cask/perforce" step triggers an
error that says:
Error: caskroom/cask was moved. Tap homebrew/cask instead.
Attempt to see if blindly following the suggestion in these error
messages gets us into a better shape.

We may return objects in one of two orders: how they appear in the .idx
(sorted by object id) or how they appear in the packfile itself. To
further complicate matters, we have two ordering variables, "i" and
"pos", and it is not clear to which order they apply.
Let's clarify this by using an unambiguous name where possible, and
leaving a comment for the variable that does double-duty.

To prepare for on-disk reverse indexes, remove a spot in
'offset_to_pack_pos()' that looks at the 'revindex' array in 'struct
packed_git'.
Even though this use of the revindex pointer is within pack-revindex.c,
this clean up is still worth doing. Since the 'revindex' pointer will be
NULL when reading from an on-disk reverse index (instead the
'revindex_data' pointer will be mmaped to the 'pack-*.rev' file), this
call-site would have to include a conditional to lookup the offset for
position 'mi' each iteration through the search.
So instead of open-coding 'pack_pos_to_offset()', call it directly from
within 'offset_to_pack_pos()'.

Now that all 'find_revindex_position()' callers have been removed (and
converted to the more descriptive 'offset_to_pack_pos()'), it is almost
safe to get rid of 'find_revindex_position()' entirely. Almost, except
for the fact that 'offset_to_pack_pos()' calls
'find_revindex_position()'.
Inline 'find_revindex_position()' into 'offset_to_pack_pos()', and
then remove 'find_revindex_position()' entirely.
This is a straightforward refactoring with one minor snag.
'offset_to_pack_pos()' used to load the index before calling
'find_revindex_position()'. That means that by the time
'find_revindex_position()' starts executing, 'p->num_objects' can be
safely read. After inlining, be careful to not read 'p->num_objects'
until _after_ 'load_pack_revindex()' (which loads the index as a
side-effect) has been called.
Another small fix that is included is converting the upper- and
lower-bounds to be unsigned's instead of ints. This dates back to
92e5c77c37 (revindex: export new APIs, 2013-10-24)--ironically, the last
time we introduced new APIs here--but this unifies the types.

'estimate_repack_memory()' takes into account the amount of memory
required to load the reverse index in memory by multiplying the assumed
number of objects by the size of the 'revindex_entry' struct.
Prepare for hiding the definition of 'struct revindex_entry' by removing
a 'sizeof()' of that type from outside of pack-revindex.c. Instead,
guess that one off_t and one uint32_t are required per object. Strictly
speaking, this is a worse guess than asking for 'sizeof(struct
revindex_entry)' directly, since the true size of this struct is 16
bytes with padding on the end of the struct in order to align the offset
field.
But, this is an approximation anyway, and it does remove a use of the
'struct revindex_entry' from outside of pack-revindex internals.

Remove direct manipulation of the 'struct revindex_entry' type as well
as calls to the deprecated API in 'packfile.c:unpack_entry()'. Usual
clean-up is performed (replacing '->nr' with calls to
'pack_pos_to_index()' and so on).
Add an additional check to make sure that 'obj_offset()' points at a
valid object. In the case this check is violated, we cannot call
'mark_bad_packed_object()' because we don't know the OID. At the top of
the call stack is do_oid_object_info_extended() (via
packed_object_info()), which does mark the object.

Convert another call of 'find_pack_revindex()' to its replacement
'pack_pos_to_offset()'. Likewise:
- Avoid manipulating `struct packed_git`'s `revindex` pointer directly
by removing the pointer-as-array indexing.
- Add an additional guard to check that the offset 'obj_offset()'
points to a real object. This should be the case with well-behaved
callers to 'packed_object_info()', but isn't guarenteed.
Other blocks that fill in various other values from the 'struct
object_info' request handle bad inputs by setting the type to
'OBJ_BAD' and jumping to 'out'. Do the same when given a bad offset
here.
The previous code would have segfaulted when given a bad
'obj_offset' value, since 'find_pack_revindex()' would return
'NULL', and then the line that fills 'oi->disk_sizep' would try to
access 'NULL[1]' with a stride of 16 bytes (the width of 'struct
revindex_entry)'.

Note that we cannot just use the existing "offset" variable to store the
