536fb676d8 (vfs_path_free): add 2nd parameter...
...to free or not to free the string representation
of vfs_path_t object.

It allows to get rid of string duplication in following cases:

vfs_path_t *vpath;
char *path;
...
vpath = vfs_path_from_str (...);
path = g_strdup (vfs_path_as_str (vpath));
vfs_path_free (vpath);

Now we can write:

vfs_path_t *vpath;
char *path;
...
vpath = vfs_path_from_str (...);
path = vfs_path_free (vpath, FALSE);

4a83daacc4 Ticket #4147: VFS timestamps: use g_get_real_time().
In the function vfs_expire(), curr_time and exp_time are declared
guint64. curr_time is initialised with a timestamp and exp_time
with this timestamp minus vfs_timeout seconds. Later there is if
(stamping->time <= exp_time). Prior to commit
a94dd7d2de curr_time was initialised with
a value larger than vfs_timeout seconds, so everything was fine. This
commit changed the initialisation to a timer starting when mc is
started. So for the first vfs_timeout seconds, the result of the
subtraction is negative, but it is a guint64, so we just get a VERY
large unsigned value and the if (stamping->time <= exp_time) is always
true. So mc thinks the vfs hasn't been used recently and goes into an
infinite loop.

If one opens a .rpm file with mc and goes into the CONTENTS.cpio and
then tries to go into the .tar.gz there (this is the usual structure of
a .rpm) after waiting vfs_timeout seconds, everything is fine. However,
before vfs_timeout seconds, mc hangs.

Solution: use g_get_real_time() instead of mc_timer_elapsed().

Thanks nvwarr at hotmail.com for finding out the reason for this bug.
