GLib has g_unix_mount_at (mount_path) already, let's add g_unix_mount_for
(file_path) for whatever path. GLib already contains some private code
for such task. Let's make this code public. This functionality is needed
by GVfs (see Bug 771431) in order to avoid copy-and-pasting.

A windows application compiled with -Wl,--subsystem,windows has no
console attached. When started from the start menu for ex, it will crash
when a function attempt to use g_log:
#10 0x00a21b26 in g_logv (log_domain=0xa842e1 <__func__.7668+329> "GLib", log_level=G_LOG_LEVEL_CRITICAL, format=0xa845c6 <__func__.7668+1070> "%s: assertion '%s' failed", args=0x28f2bc "PG"")
#11 0x00a21bb1 in g_log (log_domain=0xa842e1 <__func__.7668+329> "GLib", log_level=G_LOG_LEVEL_CRITICAL, format=0xa845c6 <__func__.7668+1070> "%s: assertion '%s' failed") at gmessages.c:1337

According to https://msdn.microsoft.com/en-us/library/zs6wbdhx.aspx:
If stdout or stderr is not associated with an output stream (for
example, in a Windows application without a console window), the file
descriptor returned is -2. In previous versions, the file descriptor
returned was -1. This change allows applications to distinguish this
condition from an error.
Check if the stream exists and has an associated descriptor and return
G_LOG_WRITER_UNHANDLED if it's not the case.

There have been some improvements to the tool recently, but it's hard to
know if those are available on a given system unless the tool provides a
--version commandline option.

It only works through its virtual methods, so while it could be
instantiated before (and this is technically an API break), any instance
of it would previously have crashed as soon as any of its methods were
called anyway.
If anybody has any problems with this ABI break, please make them known
during the 2.51 unstable development cycle and it can be reverted.

/proc/self/mountinfo is used to monitor changes of mounts with libmount.
However, GFileMonitor is used currently to monitor this file, which
doesn't work and consequently "changed" signal is never emitted. Special
monitoring needs to be used instead, same as it is used for /proc/mounts.

It turns out that CommandLineToArgvW() (at least on XP) doesn't end the argv
pointer array with a NULL, but goes straight into argv[0] string data, as per
MSDN. So gspawn-win32-helper.c:protect_wargv() counts argc too high and
overflows.

The libmount code produces somewhat different results than the older
Linux code that would parse /proc/mounts; for example, bind mounts
appear in the libmount output. To try and get as many GLib users
as possible to have the same behavior, on Linux, make GLib error out
on missing libmount unless --disable-libmount is passed.
