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.

src/utils: change map_file to not take const string argument
map_file() uses PROT_READ, so const seems fitting; however unmap_file
calls munmap/free, which do not take const, so an UNCONSTIFY is needed.
To avoid the UNCONSTIFY hack, which is likely undefined behavior or some
such, just remove the const.

Use secure_getenv when available
We probably don't want to get a privileged process to compile arbitrary

paths or default RMLVOs. But then secure_getenv is more sensible for
everything we do.

x11: add XKB protocol keymap and state creation support
These are function to create an xkb_keymap directly from XKB requests
to the X server. This opens up the possibility for X clients to use
xcb + xcb-xkb + xkbcommon as a proper replacement for Xlib + xkbfile for
keyboard support.
The X11 support must be enabled with --enable-x11 for now.
The functions are in xkbcommon/xkbcommon-x11.h. It depends on a recent
libxcb with xkb enabled. The functions are in a new libxkbcommon-x11.so,
with a new pkg-config file, etc. so that the packages may be split, and
libxkbcommon.so itself remains dependency-free.
Why not just use the RMLVO that the server puts in the _XKB_RULES_NAMES
property? This does not account for custom keymaps, on-the-fly keymap
modifications, remote clients, etc., so is not a proper solution in
practice. Also, some servers don't even set it. Now, the client just
needs to recreate the keymap in response to a change in the server's
keymap (as Xlib clients do with XRefreshKeyboardMapping() and friends).

symbols: move keysyms into LevelInfo
Instead of maintaining a syms array in the GroupInfo + sym_index's in
the levels. This simplifies the code somewhat.
In order not to alloc for every level instead of every group, we only do
it if the level has more than one keysym (with a union). Since for now
this is a special case, it actually works out better memory-wise.

This is the old array-of-structures vs. structure-of-arrays, but in this

This function was always returning -1.
Adding a test, we see that test/state.c treat the is_active functions as

Also update the documentation for the are_active functions, and add a

vmod: remove support for resolving integer to virtual modifier
This is only relevant to the virtualModifier= statement in interpret
statements in xkb_compat. The current code allows to write e.g.
virtualModifier = 4
to get the virtual modifier whose index happens to be 4 (possibly
declared in other files or sections, i.e. xkb_types). Doing this is
undeterministic, will break without notice, and not used anywhere.
Don't allow it.

compat: ignore "group" (compatibility) statements
Group compatibility statements are like the following:
group 3 = AltGr;
This currently results in:
keymap->groups[2].mask = <real mod mapped from AltGr vmod>
And we don't do any thing with this value later. The reason it exists in
XKB is to support non-XKB clients (i.e. XKB support disabled entirely in
the server), which do not know the concept of "group", and use some
modifier to distinguish between the first and second keyboard layouts
(usually with the AltGr key). We don't care about all of that, so we can
forget about it.
One artifact of this removal is that xkb_map_num_groups no longer
works, because it counted through keymap->groups (this wasn't entirely
correct BTW). Instead we add a new num_groups member to the keymap,
which just hold the maximum among the xkb_key's num_groups. This also
means we don't have to compute anything just to get the number of
groups.

Add logging API
Add new public API to provide the library users with some options to
control and customize the logging output from the library. It is based
upon the skeleton from the libabc demo libray:
https://git.kernel.org/?p=linux/kernel/git/kay/libabc.git
which is public domain and works pretty well.
This requires passing in the context object in every logging call, and
thus the conversion is done file by file. We also remove the global
warningLevel variable in favor of a verbosity level in the context,
which can be set by the user and is silent by default.
One issue is the ACTION calls, which, while nice, do not play very well
with line- and priority-based logging, and would require some
line continuation handling or keeping state or some other compromise. So
instead remove these and just inline them with their respective
warning/error. So instead of:
ERROR("Memory allocation failed\n")
ACTION("Removing all files on hardisk\n")
its something like that:
log_err("Memory allocation failed; Removing all files on harddisk\n")

Implicitly include config.h in all files
The definitions in config.h should be available in all files an
implementation detail; it can be included through the build system
instead of having each file pull it every time.
This is especially helpful with AC_USE_SYSTEM_EXTENSIONS, as _GNU_SOURCE
and friends can have an effect by merely being defined, which can lead
to some confusion if its effective for only half the files.
And we don't really support a build _without_ config.h; so, one less
