1a43d950b4 docs: Update various external links to use HEAD instead of master
Update several links to allow the remote to use its configured default
branch name, rather than specifying `master` as the default branch name.
This will help avoid breakage if any of these projects rename their
default branch in the future.

Fix a few of the links where they were hitting redirects or had moved.

483843c282 gmodule: Add locking around dlerror() for some libc implementations
Specifically, for uclibc at the moment. Other implementations may need
locking, but I haven’t checked any aside from uclibc-ng and glibc.

POSIX.1-2001 specifies that `dlerror()` is not thread-safe, but the
glibc (and likely other libc) implementation is.

Issue #399 was originally reported about eglibc, but that project has
since died and been merged back into glibc. So that’s one less thing to
worry about.

6a903ff6d7 Fix g_module_symbol() under Windows sometimes not succeeding
g_module_symbol() internally calls CreateToolhelp32Snapshot() which
in some circumstances returns ERROR_BAD_LENGTH and according to the docs
should lead to CreateToolhelp32Snapshot() being retried by the caller.

This retry logic was missing and for example led to g_module_symbol()
not succeeding if another thread happened to call the wrong function
at the wrong time.

This got noticed in the g-i build of gtk4 where g-i would call g_module_symbol()
on all gtk4 _get_type symbols and while inspecting the properties gtk4 would
spawn a thread calling SHGetSpecialFolderLocation() somewhere down the line.
During the call to SHGetSpecialFolderLocation() CreateToolhelp32Snapshot() would
return with ERROR_BAD_LENGTH for a short period of time and make g_module_symbol()
fail, which lead to "Invalid GType function" errors in g-i.

00bfb3ab44 tree: Fix various typos and outdated terminology
This was mostly machine generated with the following command:
```
codespell \
    --builtin clear,rare,usage \
    --skip './po/*' --skip './.git/*' --skip './NEWS*' \
    --write-changes .
```
using the latest git version of `codespell` as per [these
instructions](https://github.com/codespell-project/codespell#user-content-updating).

Then I manually checked each change using `git add -p`, made a few
manual fixups and dropped a load of incorrect changes.

There are still some outdated or loaded terms used in GLib, mostly to do
with git branch terminology. They will need to be changed later as part
of a wider migration of git terminology.

If I’ve missed anything, please file an issue!

6cae01c2f5 Silence clang errors about -Wformat-nonliteral due to missing intermediate attributes
By default, meson builds glib with -Werror=format=2, which
implies -Werror=format-nonliteral. With these flags, clang errors
out on e.g. the g_message_win32_error function, due to "format
string is not a string literal". This function takes a format
string, and passes the va_list of the arguments onwards to
g_strdup_vprintf, which is annotated with printf attributes.

When passing a string+va_list to another function, GCC doesn't warn
with -Wformat-nonliteral. Clang however does warn, unless the
functions themselves (g_message_win32_error and set_error) are decorated
with similar printf attributes (to force the same checks upon the
caller) - see
https://clang.llvm.org/docs/AttributeReference.html#format
for reference.

Adding these attributes revealed one existing mismatched format string
(fixed in the preceding commit).

10280deebd Meson: Override every dependency glib provides
Meson 0.54.0 added a new method meson.override_dependency() that must be
used to ensure dependency consistency. This patch ensures a project that
depends on glib will never link to a mix of system and subproject
libraries. It would happen in such cases:

The system has glib 2.40 installed, and a project does:
dependency('glib-2.0', version: '>=2.60',
  fallback: ['glib', 'glib_dep'])
dependency('gobject-2.0')

The first call will configure glib subproject because the system libglib
is too old, but the 2nd call will return system libgobject.

By overriding 'gobject-2.0' dependency while configuring glib subproject
during the first call, meson knows that on the 2nd call it must return
the subproject dependency instead of system dependency.

This also has the nice side effect that with Meson >0.54.0 an
application depending on glib can declare the fallback without knowing
the dependency variable name: dependency('glib-2.0', fallback: 'glib').

e8d471f3e1 meson: Mostly assume clang-cl is MSVC
We need to enable building the dirent and gnulib sources for clang-cl,
as we are still using the Microsoft-style headers and lib's and CRT.
We need to also do this for the following, for similar reasoning:

-Symbol export (via __declspec(dllexport))
-Dependency discovery without pkg-config files
-long long and ssize_t detection

We do, however, enable the autoptr tests for clang-cl builds.  Note that
at this point real MSVC builds are still better supported than clang-cl
builds, and it will likely remain so for at least the near future,
alhtough real MSVC builds of the GTK stack are consumable and are usable
by clang-cl.

be56d90fe9 gmodule: Add support for loading UWP packaged DLLs
LoadLibrary() is not available when building for the Universal Windows
Platform, which is used for shipping apps to the Windows Store on all
devices (Windows Desktop, Windows Phone, Surface, XBox, etc).

Apps are not allowed to load arbitrary DLLs from the system. The only
DLLs they can load are those that are bundled with the app as assets.
LoadPackagedLibrary() can be used to access those assets by filename.

The function is meant to be a drop-in replacement for LoadLibrary(),
and the HANDLE returned can be treated the same as before.

6b61395c2d build: Remove */.gitignore files
Since out-of-source-tree builds are now used after switching to meson,
we don't need .gitignore files in the source directories to ignore
build artifacts.

This fixes build errors when doing a meson build after an autotools
build, because generated files such as gio/xdp-dbus.c won't show up in
a `git status`, or be removed by a `git clean -f`, and so it won't be
obvious that such files need to be removed for the meson build to
succeed.

afd3f3beda Meson: Fix declare_dependency() calls
Turns out the fix in commit 93555577c wasn't enough, when using glib as
subproject and the parent project uses only libgio_dep, and include
<gi18n.h>, it won't find libintl.h because it's in the
include_directories of libglib_dep. Fix that by declaring dependencies
explicitly, which is the right thing to do since glib and gobject are
public dependencies of gio. That reflects what we do for the pkg-config
file as well.

This is a partial change of the previous work[0].
On 64 bit Android since android-23, 'handle = dlopen(NULL); dlsym(handle)'
doesn't work. Instead, only 'dlsym(RTLD_DEFAULT)' returns a valid pointer.

However, RTLD_DEFAULT is defined as '(void *) 0x0' on 64bit Android which
is usually used for invalid value so this patch allows the specific case.

0d81bb4e31 gmodule – Don't use RTLD_DEFAULT on Android for g_module_self() on Android 64 bit
On 64 bit Android this is #defined to 0, which is considered an invalid
library handle in all other cases. RTLD_DEFAULT is only supposed to be
used with dlsym() it seems, and the usage here was just an
"optimization" before.

By dlopen'ing NULL, we get the same on all 64 bit Android variants and it
actually works instead of erroring out. On 32 bit Android, dlopen() of
NULL unfortunately usually gives us something useless that finds no
symbols whatsoever.

553329358c gmodule: Add the visibility attribute to G_MODULE_EXPORT on gcc
For versions of GCC which support it (≥ 4), define G_MODULE_EXPORT as
__attribute__((visibility("default"))). This is normally a no-op, unless
compiling with -fvisibility=hidden, in which case it marks a symbol to
be publicly exported from the library, which is what G_MODULE_EXPORT is
for. Previously G_MODULE_EXPORT has only worked on Windows.

The compatibility check for whether the compiler supports
__attribute__((visibility)) is based on the __GNUC__ define, and is
similar to the check done in configure.ac for defining G_GNUC_INTERNAL.

 2) we dropped generation of .def files quite some time ago (except for

have if you have lib.exe) and fix the .lib rules to use lib.exe.
