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.

Add a note to the documentation for g_file_new_for_commandline_arg()
that this function is intended to operate on strings already in the GLib
filename encoding on Windows.
This has been the case for a long time, but this documents the
requirement.

Usually async methods copy/ref its arguments so caller can
forget about them. g_file_replace_contents_async() and
g_output_stream_write_async() are exceptions.

Assume unix platforms support the original POSIX.1 standard.
Specifically, assume that if G_OS_UNIX, then we have chown(),
getcwd(), getgrgid(), getpwuid(), link(), <grp.h>, <pwd.h>,
<sys/types.h>, <sys/uio.h>, <sys/wait.h>, and <unistd.h>.
Additionally, since all versions of Windows that we care about also
have <sys/types.h>, we can remove HAVE_SYS_TYPES_H checks everywhere.
Also remove one include of <sys/times.h>, and the corresponding
configure check, since the include is not currently needed (and may
always have just been a typo for <sys/time.h>).

It's not difficult to do; not all backends implement it, and for some
it may be difficult to implement query_info_on_read(), so let's just
do both.

In the real_..._async wrapper for GFile.measure_disk_usage, skip the
wrapping of the progress callback in the case that the user gave a NULL
callback to the async function. This is a performance improvement
because the sync version won't have to do continuous sampling of the
clock to issue a call to the wrapper which will then do nothing.
Unfortunately, I made this simplifying assumption when writing the
wrapper, but forgot to actually implement it when making the sync call.
As a result, the wrapper is still called, and invokes the NULL callback,
causing a segfault.
Make sure we pass NULL if the user's callback was NULL.

Previously, g_file_copy() would (on Unix) create files with the
default mode of 644. For applications which might at user request
copy arbitrary private files such as ~/.ssh or /etc/shadow, a
world-readable copy would be temporarily exposed.
This patch is suboptimal in that it *only* fixes g_file_copy()
for the case where both source and destination are instances of
GLocalFile on Unix.
The reason for this is that the public GFile APIs for creating files
allow very limited control over the access permissions for the created
file; one can either say a file is "private" or not. Fixing
this by adding e.g. g_file_create_with_attributes() would make sense,
except this would entail 8 new API calls for all the variants of
_create(), _create_async(), _replace(), _replace_async(),
_create_readwrite(), _create_readwrite_async(), _replace_readwrite(),
_replace_readwrite_async(). That can be done as a separate patch
later.

Previously, we called g_file_query_info() *again* on the source at the
very end of the copy. This has the lame semantics that if the source
happened to be deleted, we would fail to apply attributes to the
destination. This could even be a security flaw.
This commit changes things so that we query info from the source
*stream* after opening - i.e. on Unix we use the proper fstat() and
friends. That way we operate more atomically.

In the *_async_thread() functions, call the corresponding synchronous
function instead of calling the interface vfunc, which can be NULL.
In some cases the check for the vfunc == NULL was done, but to be
consistent it is better to always call the synchronous version (and the
code is simpler).

We need to close the stream *before* applying the file modes, because
g_file_replace() allocates a temporary file. At the moment we're
applying the modes to the extant file, then immediately rename()ing
over it with the default perms.
This regressed with commit 166766a89f.
The real fix here is to have g_file_create_with_info() so that we can
atomically create a file with the permissions we want.
