Add an install target rule to the Makefiles in contrib/credential in the
same manner as in other Makefiles in contrib such as for contacts or
subtree.

Update these Makefiles to be in line with other Makefiles from contrib
such as for contacts or subtree by making the following changes:
* Make the default settings after including config.mak.autogen and
config.mak.
* Add the missing $(CPPFLAGS) to the compiler command as well as the
missing $(CFLAGS) to the linker command.
* Use a pattern rule for compilation instead of a dedicated rule for
each compile unit.
* Get rid of $(MAIN), $(SRCS) and $(OBJS) and simply use their values
such as git-credential-libsecret and git-credential-libsecret.o.
* Strip @ from $(RM) to let the clean target rule be verbose.
* Define .PHONY for all special targets (all, clean).

Update meson-based build procedure to cover contrib/ and other
places as well.
* ps/meson-contrib-bits:
ci: exercise credential helpers
ci: fix propagating UTF-8 test locale in musl-based Meson job
meson: wire up static analysis via Coccinelle
meson: wire up git-contacts(1)
meson: wire up credential helpers
contrib/credential: fix compilation of "osxkeychain" helper
contrib/credential: fix compiling "libsecret" helper
contrib/credential: fix compilation of wincred helper with MSVC
contrib/credential: fix "netrc" tests with out-of-tree builds
GIT-BUILD-OPTIONS: propagate project's source directory
|

We've got a couple of credential helpers in "contrib/credential", all
of which aren't yet wired up via Meson. Do so.
Note that ideally, we'd also wire up t0303 to be executed with each of
the credential helpers to verify their functionality. Unfortunately
though, none of them pass the test suite right now, so this is left for
a future change.

The "libsecret" credential helper does not compile when developer
warnings are enabled due to three warnings:
- contrib/credential/libsecret/git-credential-libsecret.c:78:1:
missing initializer for field ‘reserved’ of ‘SecretSchema’
[-Werror=missing-field-initializers]. This issue is fixed by using
designated initializers.
- contrib/credential/libsecret/git-credential-libsecret.c:171:43:
comparison of integer expressions of different signedness: ‘int’
and ‘guint’ {aka ‘unsigned int’} [-Werror=sign-compare]. This
issue is fixed by using an unsigned variable to iterate through
the string vector.
- contrib/credential/libsecret/git-credential-libsecret.c:420:14:
unused parameter ‘argc’ [-Werror=unused-parameter]. This issue is
fixed by checking the number of arguments, but in the least
restrictive way possible.

Explicitly set the default goal at the very top of various makefiles.
This is already present in some makefiles, but not all of them.
In particular, this corrects a regression introduced in a38edab7c8
(Makefile: generate doc versions via GIT-VERSION-GEN, 2024-12-06). That
commit added some config files as build targets for the Documentation
directory, and put the target configuration in a sensible place.
Unfortunately, that sensible place was above any other build target
definitions, meaning the default goal changed to being those
configuration files only, rather than the HTML and man page
documentation.

Since 0ce02e2f (credential/libsecret: store new attributes, 2023-06-16)
a test that stores empty username and password fails when
t0303-credential-external.sh is run with
GIT_TEST_CREDENTIAL_HELPER=libsecret.
Retrieve empty password carefully. This fixes test:
ok 14 - helper (libsecret) can store empty username

Update two credential helpers to correctly match which credential
to erase; they dropped not the ones with stale password.
* mh/credential-erase-improvements-more:
credential/wincred: erase matching creds only
credential/libsecret: erase matching creds only
|

The credential erase request typically includes protocol, host, username
and password.
credential-libsecret erases a stored credential if it matches protocol,
host and username, regardless of password.
This is confusing in the case the stored password differs from that
in the request. This case can occur when multiple credential helpers are
configured.
Only erase credential if stored password matches request (or request
omits password).
This fixes test "helper (libsecret) does not erase a password distinct
from input" when t0303 is run with GIT_TEST_CREDENTIAL_HELPER set to
"libsecret". This test was added in aeb21ce22e (credential: avoid
erasing distinct password, 2023-06-13).

d208bfd (credential: new attribute password_expiry_utc, 2023-02-18)
and a5c76569e7 (credential: new attribute oauth_refresh_token)
introduced new credential attributes.
libsecret assumes attribute values are non-confidential and
unchanging, so we encode the new attributes in the secret, separated by
newline:
hunter2
password_expiry_utc=1684189401
oauth_refresh_token=xyzzy
This is extensible and backwards compatible. The credential protocol
already assumes that attribute values do not contain newlines.
Alternatives considered: store password_expiry_utc in a libsecret
attribute. This has the problem that libsecret creates new items
rather than overwrites when attribute values change.

The libsecret credential helper reads the newline-delimited
protocol stream one line at a time by repeatedly calling fgets() into a
fixed-size buffer, and is thus affected by the vulnerability described
in the previous commit.
To mitigate this attack, avoid using a fixed-size buffer, and instead
rely on getline() to allocate a buffer as large as necessary to fit the
entire content of the line, preventing any protocol injection.
In most parts of Git we don't assume that every platform has getline().
But libsecret is primarily used on Linux, where we do already assume it
(using a knob in config.mak.uname). POSIX also added getline() in 2008,
so we'd expect other recent Unix-like operating systems to have it
(e.g., FreeBSD also does).
Note that the buffer was already allocated on the heap in this case, but
we'll swap `g_free()` for `free()`, since it will now be allocated by
the system `getline()`, rather than glib's `g_malloc()`.

The libsecret credential helper does not mark its build artifact as
ignored, so running "make" results in a dirty working tree.
Mark the "git-credential-libsecret" binary as ignored to avoid the above.

In C it isn't required to specify that all members of a struct are
zero'd out to 0, NULL or '\0', just providing a "{ 0 }" will
accomplish that.
Let's also change code that provided N zero'd fields to just
provide one, and change e.g. "{ NULL }" to "{ 0 }" for
consistency. I.e. even if the first member is a pointer let's use "0"
instead of "NULL". The point of using "0" consistently is to pick one,
and to not have the reader wonder why we're not using the same pattern
everywhere.

Replace Free Software Foundation address in license notices

The mailing address for the FSF has changed over the years. Rather than
updating the address across all files, refer readers to gnu.org, as the
GNU GPL documentation now suggests for license notices. The mailing
address is retained in the full license files (COPYING and LGPL-2.1).
The old address is still present in t/diff-lib/COPYING. This is
intentional, as the file is used in tests and the contents are not
expected to change.

Credentials exposed by the secret service DBUS interface may be locked.
Setting the SECRET_SEARCH_UNLOCK flag will make the secret service
unlock these secrets, possibly prompting the user for credentials to do
so. Without this flag, the secret is simply not loaded.

This is based on the existing gnome-keyring helper, but instead of
libgnome-keyring (which was specific to GNOME and is deprecated), it
uses libsecret which can support other implementations of XDG Secret
Service API.
Passes t0303-credential-external.sh.
