For some reason, `time_t` is defined as being 32 bits wide on that
platform, which causes truncation of the timestamps from `struct stat`.
Avoid that problem by consistently using a 64-bit return value from the
`struct stat` accessors.
Helps: #3039
`GLocalFileStat` is a platform-specific abstraction around `struct stat`
or `struct statx`. If `struct statx` is available, it will use that by
preference as it has more features.
`glocalfileinfo.c` was, in some places, incorrectly accessing the fields
of `GLocalFileStat` directly rather than through its `_g_stat_*()`
getters. While it correctly accounted for the platform-specific
differences between `st_mtimensec` and `st_mtim.tv_nsec`, it hadn’t been
updated to deal with `stx_mtime`.
On Android, `st_mtimensec` is defined as a fallback for
`st_mtim.tv_nsec` (even though it doesn’t need to be). This caused GLib
to take the `st_mtimensec` code path rather than the `stx_mtime` code
path, and hence try to dereference `st_mtim` in a `struct statx`.
Fix that by correctly using the `_g_stat_*()` getters consistently.

gio/glocalfileinfo.c: In function ‘get_access_rights’:

`g_local_file_fstatat()` needs to fall back to returning an error if
`fstatat()` isn’t defined, which is the case on older versions of macOS
(as well as Windows, which was already handled). Callers shouldn’t call
`g_local_file_fstatat()` in these cases. (That’s already the case.)

This currently just implements the same functionality as the existing
`stat()`/`fstat()`/`fstatat()`/`lstat()` calls, although where a reduced
field set is requested it may return faster.
Helps: #1970
This is a step towards supporting `statx()`, which allows the set of
fields it returns to be specified by the caller. Currently, the existing
`stat()` and `fstat()` calls continue to be made, and there are no
behavioural changes — but the new wrapper functions will be extended in
future.
Helps: #1970
Some editors automatically remove trailing blank lines, or
automatically add a trailing newline to avoid having a trailing
non-blank line that is not terminated by a newline. To avoid unrelated
whitespace changes when users of such editors contribute to GLib,
let's pre-emptively normalize all files.
Unlike more intrusive whitespace normalization like removing trailing
whitespace from each line, this seems unlikely to cause significant
issues with cherry-picking changes to stable branches.

The previously implementation considered a file to be a mountpoint if
its parent is on a different device. / is its own parent, so by this
definition it is not a mountpoint.
But / is (generally) listed in fstab, and fstab(5) defines the
directories it contains to be mountpoints. This attribute should follow
that definition (and reasonable expectation): the root directory is a
mountpoint.
So, add a special-case for the case where the file's parent has the same
st_dev and st_ino as the file, which is true only at the root.
Test this attribute at / (only on POSIX), /proc (but only on Linux), and
at many files and directories created by the test suite (which cannot be
mountpoints).
This commit adds new W32-only functions to gstdio.c,
and a new header file, gstdioprivate.h.
These functions are:
g_win32_stat_utf8()
g_win32_lstat_utf8()
g_win32_fstat()
and they fill a private structure, GWin32PrivateStat,
which has all the fields that normal stat has, as well as some
extras.
These functions are then used throughout glib and gio to get better
data about the system. Specifically:
* Full, 64-bit size, guaranteed (g_stat() is forced to use 32-bit st_size)
* Full, 64-bit file identifier (st_ino is 0 when normal stat() is used, and still is)
* W32 File attributes (which stat() doesn't report); in particular, this allows
symlinks to be correctly identified
* Full, 64-bit time, guaranteed (g_stat() uses 32-bit st_*time on 32-bit Windows)
* Allocated file size (as a W32 replacement for the missing st_blocks)
st_mode remains unchanged (thus, no S_ISLNK), so when these are given back to
glib users (via g_stat(), for example, which is now implemented by calling g_win32_stat_utf8),
this field does not contain anything unexpected.
g_lstat() now calls g_win32_lstat_utf8(), which works on symlinks the way it's supposed to.
Also adds the g_win32_readlink_utf8() function, which behaves like readlink()
(including its inability to return 0-terminated strings and inability to say how large
the output buffer should be; these limitations are purely for compatibility with
existing glib code).
Thus, symlink support should now be much better, although far from being complete.
A new W32-only test in gio/tests/file.c highlights the following features:
* allocated size
* 64-bit time
* unique file IDs

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>).

* glocalfileinfo.h: Introduce a macro GLocalFileStat that is the
normal struct stat on Unix but struct _stati64 on Windows to have
access to 64-bit file size information. Use that instead of struct
stat in the functions declared here in this private header.
* glocalfileinfo.c: Corresponding changes. Move some G_OS_WIN32,
S_ISLNK and HAVE_UTIMES ifdefs and add some more to avoid compiler
warnings about unused functions and variables. Don't set
meaningless attributes like inode numbers on Windows.
