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().

Bundled libintl did not support linking to internal static
libraries (libmc in our case): directly specified static
libraries are not pulled by libtool and are not usable for
dynamic libraries as PIC-related flags are not passed for
compilation.
This renders bundled libintl library unusable.
The change drops libintl bundling support and always relies
on external libintl (or falls back to disabled NLS).
On a related note gettext-0.20 drops support for bundling
or libintl and this change will ease migration to newer version.
The change is tested on x86_64-gentoo-linux-musl: mc builds
and links all tests successfully. A few tests fail for lack
of NLS support.

How to reproduce the bug:
* compile mc with gpm support
* run the gpm daemon on the console
* login to the machine with ssh from console on another machine
* run mc
At this situation, keyboard response will be sluggish and mc will consume
CPU time when idle. The reason is that mc is trying to reopen the Gpm
connection over and over again and gpm will try to close the connection
over and over again (because the user is not on the local console).

When content of a large directory is being sorted by file names, a
significant amount of CPU time is spent in str_utf8_normalize() that is
called from str_utf8_create_key_gen().
For example, /usr/bin/ contains 5437 files on my Archlinux box. Running
mc /usr/bin/ /usr/bin/ takes approx. 75 000 000 CPU instructions to sort
file names, or 25% of total program run time. From these 75 000 000
instructions, 42 500 000 instruction are spent in str_utf8_normalize().
str_utf8_normalize() uses g_utf8_normalize() to do the work.
g_utf8_normalize() is a heavyweight function, that converts UTF-8 into
UCS-4, does the normalization and then converts UCS-4 back into UTF-8.
Since file names are composed of ASCII characters in most cases, we can
speed up str_utf8_normalize() by checking if the heavyweight Unicode
normalization is actually needed. Normalization of ASCII string is
no-op, so it is effectively "normalized" by just strdup().
With this patch, running mc /usr/bin/ /usr/bin/ requires just 37 000 000
instructions to sort the file names (down from 75 000 000) and 4 500 000
instuctions to do str_utf8_normalize() (down from 42 500 000).

actual work.
Note that in the user-facing documentation (extfs/helpers/README) there are
two things we prefer *not* to mention about vfs_parse_filedate's ability:
* Accepting the format "MM-DD-YY hh:mm[:ss]", as this two-digit year is
more likely to confuse readers of such dates.
* Accepting '/', instead of '-', as the separator in MM-DD-YYYY. (Considering
that some scripts do use '/', maybe we should mention it?)

Note: considering that this feature hasn't worked, we may consider removing it
entirely or partially (e.g., escaping) in order to simplify the code, as nobody
has grown used to it. It seems, based on the "hex mode" mentioned in the manual
page, that in the past there was no "normal" search in hex mode, and quoted
strings were the only easy way to look for text. This is no longer the case
nowadays.
Note: the characters in the quoted string are copied out as-is to the regexp.
No regexp-quoting is currently done. We may want to revisit this issue when we
work on ticket #3695.
