keysym: fix locale dependence in xkb_keysym_from_name()

We currently use strcasecmp, which is locale-dependent. In particular,
one well-known surprise even if restricted just ASCII input is found in
the tr_TR (Turkish) locale, see e.g.
https://msdn.microsoft.com/en-us/library/ms973919.aspx#stringsinnet20_topic5

We have known to avoid locale-dependent functions before, but in this
case, we forgot.

Fix it by implementing our own simple ASCII-only strcasecmp/strncasecmp.
Might have been possible to use strcasecmp_l() with the C locale, but
went the easy route.

Side advantage is that even this non-optimized version is faster than
the optimized libc one (__strcasecmp_l_sse42) since it doesn't need to
do the locale stuff. xkb_keysym_from_name(), which uses strcasecmp
heavily, becomes faster, and so for example Compose file parsing, which
uses xkb_keysym_from_name() heavily, becomes ~20% faster.

This is more or less what is implemented here:
https://git.gnome.org/browse/gtk+/tree/gdk/x11/gdkkeys-x11.c?h=3.19.10#n1131

The implementation here is more technically correct but should provide
the same results.

state: allow different modes for calculating consumed modifiers

The current functions dealing with consumed modifiers use the
traditional XKB definition of consumed modifiers (see description in the
added documentation). However, for several users of the library (e.g.
GTK) this definition is unsuitable or too eager. This is exacerbated by
some less-than-ideal xkeyboard-config type definitions (CTRL+ALT seems
to cause most grief...).

So, because we
- want to enable alternative interpretations, but
- don't want to expose too much internal details, and
- want to keep things simple for all library users,
we add a high-level "mode" parameter which selects the desired
interpretation. New ones can be added as long as they make some sense.

All of the old consumed-modifiers functions keep using the traditional
("XKB") mode. I mark xkb_state_mod_mask_remove_consumed() and as
deprecated without adding a *2 variant because I don't it is very useful
(or used) in practice.

Alternative modes are added in subsequent commits (this commit only adds
a mode for the existing behavior).

Of particular note, if the locale root is not specified, then xkbcommon

to look in the standard system location, /usr/share/X11/locale.

Otherwise, xkbcommon will error when it can't find them, e.g.:

Modifications to make 'make check' test complete for Mac OS X

bench: Modify benchmarks for a wider range of platforms

 - Add the new files bench.c and bench.h to implement a timer module.
 - Implement the module with clock_gettime(), mach_absolute_time(), or
   gettimeofday(), depending on a given platform.
 - Replace the time measurement code of the benchmark programs with the
   functions of the module.

test/x11comp: Fix contention between X11 and Xvfb on Mac OS X

 - Abandon use of -displayfd.
 - Have x11comp itself look for an unused X11 display number instead.

test/x11comp: remove duplicate FOUR_LEVEL_KEYPAD from test keymap

The `test/data/keymaps/host.xkb` file contains a duplicate definition of
this type. On my computer (linux, xkbcomp 1.3.0, xserver 1.17.2), the
test passes as is, but if I remove the duplicate definition, the
roundtrip brings it back and the test fails. I can also reproduce it
without relation to the test, by loading `test/data/keymaps/host.xkb`
(without the duplicate) using

    xkbcomp -I $(pwd)/test/data/keymaps/host.xkb $DISPLAY

and downloading it again using

    xkbcomp $DISPLAY out.xkb

the duplicate is added. On Mac OS X however, the duplicate is removed
(correctly), so the test fails there.

xkbcommon itself, which was forked from xkbcomp, doesn't have this bug;
in fact, doing

    ./test/print-compiled-keymap -k keymaps/host.xkb

removes the duplicate if it is present.

This is (probably) a regression in xkbcomp or xserver compared to the
versions used in Mac OS X. Since getting a patch for any of these two is
hopeless from my experience, I did not try to investigate further.

I am not sure why, but if I also add a `PC_SUPER_LEVEL2` type, the
duplicate of `FOUR_LEVEL_KEYPAD` doesn't show up. Hopefully the test
will work on all platforms now.

Update NEWS

Signed-off-by: Ran Benita <ran234@gmail.com>

Change initial symbol file versions to V_0.5.0

It will be quite confusing to use V_0.4.3 since this was already
released without symbol versioning.

Hopefully this doesn't cause any trouble for people who are using -git.
