This change increases throughput when copying files for some filesystems
(Modified by Philip Withnall <withnall@endlessm.com> to add more error
handling.)

This is a variant of g_file_get_path() which returns a const string to
the caller, rather than transferring ownership.
I've been carrying `gs_file_get_path_cached()` in libgsystem and it
has seen a lot of use in the ostree and flatpak codebases. There are
probably others too.
I think language bindings like Python/Gjs could also use this to avoid
an extra malloc (i.e. we could transparently replace
`g_file_get_path()` with `g_file_peek_path()`.
(Originally by Colin Walters. Tweaked by Philip Withnall to update to
2.56, change the function name and drop the locking.)

Try and make it a bit more obvious that g_file_query_exists() is
generally A Bad Idea.

This adds g_file_load_bytes() to make it more convenient to
load the contents of a GFile as GBytes.
It includes a special casing for gresources to increase the
chances that the GBytes directly references the embedded data
instead of copying to the heap.

Prevent the situation where errno is set by function A, then function B
is called (which is typically _(), but could be anything else) and it
overwrites errno, then errno is checked by the caller.
errno is a horrific API, and we need to be careful to save its value as
soon as a function call (which might set it) returns. i.e. Follow the
pattern:
int errsv, ret;
ret = some_call_which_might_set_errno ();
errsv = errno;
if (ret < 0)
puts (strerror (errsv));
This patch implements that pattern throughout GLib. There might be a few
places in the test code which still use errno directly. They should be
ported as necessary. It doesn’t modify all the call sites like this:
if (some_call_which_might_set_errno () && errno == ESOMETHING)
since the refactoring involved is probably more harmful than beneficial
there. It does, however, refactor other call sites regardless of whether
they were originally buggy.

The g_file_copy() documentation didn't mention if
G_FILE_COPY_ALL_METADATA was applicable or not, and users were led to
call g_file_copy_attributes() to specify it after the g_file_copy()
call, unless they checked the source (been there, done that).

This is small enough that it shouldn't cause problems on most machines
we support, but big enough to increase throughput on a lot of devices
and network protocols.
Note that the actual value is 256k minus malloc overhead, so that it
fits nicely in a 256k block (as suggested by Alexander Larsson).

If we have an input parameter (or return value) we need to use (nullable).
However, if it is an (inout) or (out) parameter, (optional) is sufficient.
It looks like (nullable) could be used for everything according to the
Annotation documentation, but (optional) is more specific.
gvfs commit b358ca "Make sure metadata is always returned by
query_writable_namespaces()" changed the
query_writable_namespaces vfunc to never return NULL, but the error
checking in g_daemon_file_query_writable_namespaces still assumes vfunc
failure implies NULL return value and GError set. This causes a memory
leak as on failure the GError will be set but the vfunc implementation
will have created its own default list so NULL will not be returned, and
the GError will never be cleared.
This commit directly checks if the GError is set to detect failures,
my_error is directly dereferenced in the error block anyway.
This also removes an unneeded call to g_file_attribute_info_new(); as
the vfunc always returns us a non-NULL GFileAttributeInfoList.

In g_file_make_directory_with_parents(), the my_error variable is used
for several different purposes throughout the whole function, not all of
which are obvious. This explains the situation with some comments.

So shortcut it.
I wrote this patch less as a performance optimization and more as a
clarification, so that people looking at the code can be assured of this
invariant.

A critical message is printed when a parameter of g_file_equal() is not
a GFile. When we read the documentation before this commit, we can think
that passing NULL or another type than GFile is allowed, but it is not
the case.
Another option is to allow NULL parameters. But for consistency with
e.g. g_str_equal(), it's probably better to keep the code as is.
