The patch introduces mnt_monitor_enable_*() functions (now for
userspace only) to make the API easy to use for high-level purpose.

It's usually enough to us [e]poll() to monitor kernel mount table, but
there is no way how to monitor changes in userspace mount options
(e.g. _netdev). The management of these mount options is completely
hidden in libmount and /rub/mount/utab is private libmount file.
This patch introduces new libmnt_mount API to monitor also userspace
mount table.

It seems that gtk-docs stuff is confused when we use version.xml
(package version) and xml/version.xml (library version functions).

* mnt_new_fs() returns object with refcount=1
* mnt_free_fs() does not care about reference counter
* new functions mnt_ref_fs() and mnt_unref_fs()
* mnt_table_add_fs() and mnt_table_rem_fs() uses reference counter
* libmmnt_context uses reference counter for internal FS (as it could be
shared outside the context)
* backwardly incompatible change:
- FS could be deallocated after mnt_table_remove_fs()
* it's recommended to use mnt_unref_fs() after mnt_table_add_fs()

Currently you have to use mnt_table_remove_fs() + mnt_free_fs() to
destroy the list in the table. This is complicated in same situations.
This patch allows to use mnt_free_fs() only.

This is more robust implementation of mnt_get_mountpoint() that does
not ignore bind mountpoints (mount --bind /mnt /mnt) as it does not
depend on st_dev numbers.

* don't teach people C by header files, so use warn_unused_result
attribute only on places where we return allocated memory (to avoid
leaks in applications).
* merge multiple function attributes to the one list to make it
usable with gtk-doc

In some cases (for example if only one mount argument is given) may be
mount request ambivalent:
# mount /foo
and fstab:
/dev/sda5 /foo rw 0 0
/foo /bar bind 0 0
The libmount allows to swap between source and target (if
source is not LABEL or UUID) by default. The new function
mnt_context_disable_swapmatch()
allows to disable this feature.

This function was never implemented, but the proto has existed since the
inception of the library. As the libmnt_table struct doesn't include a
member necessary to carry the name of the table, simply discard this
prototype. If ever a need to break ABI comes up, perhaps this could be
revisited.
