When `copy_file_range()` support was added, I used the definition of
`copy_file_range()` from Linux, which uses `loff_t` to abstract the
different `off*_t` types.
`loff_t` doesn’t exist on FreeBSD, so this doesn’t compile, and was
caught in subsequent asynchronous CI.
Define `loff_t` with a fallback value if it’s not defined, which should
fix this and other uses of `loff_t` in `gfile.c` (for example, if
FreeBSD ever starts declaring `splice()`).

GTK lost it's '+' suffix back in 2019, according to
<https://mail.gnome.org/archives/gtk-devel-list/2019-February/msg00000.html>
This commit can be re-generated with:
git grep -l GTK+ \
| grep -v -e ^NEWS -e ^glib/tests/collate.c \
| xargs sed -i 's/GTK+/GTK/g'
Most of the changes are in comments and documentation.
Use more modern styling to the code added in the previous patch:
- split 'label: stmt; stmt;' into multiple lines
- add default: label with g_assert_not_reached() [yes, it's a bit
weird adding an assertion inside code that handles assertions, but
we should be okay since g_assertion_message_* are not public
functions and should only be used by our macros]
- use <inttypes.h> for shorter format strings
Note, however, that using uint64_t in gtestutils.h is not feasible,
since it would require adding an '#include <stdint.h>' with potential
unintended namespace pollution to older clients.

While x86_64 has enough precision in long double to do a round trip
from guint64 to long double and back, this is platform-specific, and
is a disservice to users trying to debug failing unit tests on other
architectures where it loses precision for g_assert_cmp{int,uint,hex}.
See also https://bugzilla.gnome.org/show_bug.cgi?id=788385 which
mentions having to add casts to specifically silence the compiler on
platforms where the precision loss occurs.
Meanwhile, g_assert_cmpuint() does an unsigned comparison, but outputs
signed values if the comparison fails, which is confusing.
Fix both issues by introducing a new g_assertion_message_cmpint()
function with a new 'u' numtype. For backwards compatibility, the
macros still call into the older g_assertion_message_cmpnum() when not
targetting 2.78, and that function still works when passed 'i' and 'x'
types even though code compiled for 2.78 and later will never invoke
it with numtype anything other than 'f'. Note that g_assert_cmpmem
can also take advantage of the new code, even though in practice,
comparison between two size_t values representing array lengths that
can actually be compiled is unlikely to have ever hit the precision
loss. The macros in signals.c test code does not have to worry about
versioning, since it is not part of the glib library proper.
Closes#2997

While it can’t be used in all situations, it is a little bit faster than
`splice()` in some situations, basically if the file system supports
copy on write. In other situations it’s no slower than `splice()`.
See `man copy_file_range` for the situations where it doesn’t work. In
all of these situations, it will return an error, and the GLib code will
fall through and try the existing `splice()` copy code instead.
From my testing of `time gio copy A B` with a 9GB file, the `splice()`
code path takes 22s, and the `copy_file_range()` code path takes 20s.

The start of the `g_file_copy()` implementation stats the source file to
find all the attributes to copy onto the destination file, so it makes
sense to get it to store the source file size at the same time.
This saves a subsequent `stat()` call on the source FD in the btrfs
reflink or splice code. Every little helps.

When cross-building with a non-Linux target, linux/netlink.h will not
actually be buildable, even if distributions typically put it in
/usr/include and thus exposed to the cross-compiler.
Something has changed recently which causes this error to now be emitted
when building on Windows msys2-mingw32:
```
../gio/gwin32networkmonitor.c: In function 'win_network_monitor_get_ip_info':
../gio/gwin32networkmonitor.c:92:15: error: storing the address of local variable 'prefix' in '*dest' [-Werror=dangling-pointer=]
92 | *dest = (guint8 *) &prefix.Prefix.Ipv4.sin_addr;
| ~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
```
If `IP_ADDRESS_PREFIX` is defined as a scalar rather than a pointer,
that could explain the problem.
Change the function to always operate on a pointer to avoid any
potential such issues.

This should hopefully stop the kernel spending a lot of memory and disk
bandwidth creating coredumps for them unnecessarily, which slows down
the rest of the tests and generally wastes resources.

I’ve finally found the right place in the docs to put this stuff.
This doesn’t auto-link this section from every string in the GLib
documentation, but I think that at this point (with gtk-doc in
maintenance mode, and gi-docgen not fully applied to GLib) I don’t think
we can do any better. The perfect is the enemy of the good, and having
this stuff documented somewhere means that someone can link to it from
multiple places in future *somehow*.

Apparently 3 hashes is too many, and as a result this line is not
displayed properly in the HTML documentation. 2 hashes seems to be
just right, as can be seen with:
$ git grep '^ \* ##' | wc -l

The gio/tests/socket-client.c doesn't use GSocketClient, which makes the
filename confusing. What the file actually tests is the GSocket. Rename
it to socket-testclient.c
The corresponding GSocket server test file naming doesn't conflict with other
class names, but rename it to socket-testserver.c for consistency.

Otherwise it might look like it would only start spawning threads when
