This introduces no functional changes, but makes the refcount handling a
little easier to follow by no longer splitting a ref/unref pair across
three callbacks. Now, the ref/unref pairs are all within function-local
scopes.

Expose a function that prepares an attribute query string to be passed
to g_file_query_info() to get a list of attributes normally copied with
the file. This function is used by the implementation of
g_file_copy_attributes, and it's useful if one needs to split
g_file_copy_attributes into two stages, for example, when nautilus does
a recursive move of a directory. When files are moved from the source
directory, its modification time changes. To preserve the mtime on the
destination directory, it has to be queried before moving files and set
after doing it, hence these two stages.

Don’t call `g_file_query_exists()` followed by `g_file_delete()`. Just
call `g_file_delete()` and check the error.

Add support for x-gvfs-notrash mount option, which allows to disable
trash functionality for certain mounts. This might be especially useful
e.g. to prevent trash folder creation on enterprise shares, which are
also accessed from Windows...

The G_FILE_ATTRIBUTE_STANDARD_CONTENT_TYPE attribute doesn't have to be
always set. See https://gitlab.gnome.org/GNOME/gvfs/-/merge_requests/68
for more details. In that case, the g_file_query_default_handler function
fails with the "No application is registered as handling this file" error.
Let's fallback to the "standard::fast-content-type" attribute instead to
fix issues when opening such files.

Documentation says that g_file_peek_path() returns exactly the same
what g_file_get_path(), but this is not true. Apart from that the code
segfaults for some uris (e.g. for "trash:///"), it returns target-uri
for trash and recent schemes. This is unexpected and can lead to various
issues among others because the target-uri paths are not automatically
translated back to GDaemonFile as it is done with gvfsd-fuse paths.
g_file_get_path() returns NULL for trash and recent schemes, because
fuse paths are not provided for those schemes. So g_file_peek_path()
should return NULL as well. It is up to the concrete application to
use target-uri when appropriate.
This change was made as a part of commit 4808a957, however, neither
the commit message, neither the corresponding bug doesn't mention this
crucial change and doesn't give any clear reasoning. So let's revert
this.
The string is already translated in `GLocalFile`, so this doesn’t
introduce a new translatable string.

If a copy operation is started with `G_FILE_COPY_TARGET_DEFAULT_PERMS`,
don’t create the destination file as private. Instead, create it with
the process’ current umask (i.e. ‘default permissions’).
This is a partial re-work of commit d8f8f4d637, with

Fixes: #174
It is expected that `g_file_move()` moves symlink file itself, not its
target. Unfortunately, copy and delete fallback passes `GFileCopyFlags`
and don't explicitly use `G_FILE_COPY_NOFOLLOW_SYMLINKS`. This may cause
that symlink target is copied and symlink itself is removed. Let's
explicitly pass `G_FILE_COPY_NOFOLLOW_SYMLINKS` to the copy operation to
prevent this unexpected behavior.
https://gitlab.gnome.org/GNOME/glib/issues/986
The `G_FILE_COPY_NOFOLLOW_SYMLINKS` flag doesn't make sense for move operation,
neither local implementation doesn't handle this flag in any way. Therefore
this paragraph should be removed from the docs (it was probably copy&pasted
from `g_file_copy()` docs by mistake).
Closes: https://gitlab.gnome.org/GNOME/glib/issues/986
file_copy_fallback creates new files with default permissions and
set the correct permissions after the operation is finished. This
might cause that the files can be accessible by more users during
the operation than expected. Use G_FILE_CREATE_PRIVATE for the new
files to limit access to those files.
The g_app_info_launch_uris_async() and g_app_info_launch_uris_finish()
functions are crucial to fix g_app_info_launch_default_for_uri_async()
to be really asynchronous.
This patch also adds GDesktopAppInfo implementation of that vfuncs.
The implementation may still use some synchronous calls to local MIME DB.

This change increases throughput when copying files for some filesystems

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.)

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.
