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.

keysym: add xkb_keysym_to_{lower,upper}
These functions are needed later; they are not API functions. The
capitalization is not locale sensitive.

keysym-utf: also translate special keysyms like Tab and Return
The keysym2ucs.c file apparently leaves out some keysyms, which libX11
deals with separately (like in _XkbHandleSpecialSym()).
The problematic keysyms are the keypad ones (for which we already added
some support) and keysyms which use 0xff** instead of 0x00** < 0x20.
This code should fix them properly, as much as I could gather from
libX11 and http://www.cl.cam.ac.uk/~mgk25/ucs/keysym2ucs.c and other
sources (which are not aware of locale).

Add xkb_keysym_from_name() flags argument for case-insensitive search
This adds a flags argument to xkb_keysym_from_name() so we can perform a
case-insensitive search. This should really be supported as many keysyms
have really weird capitalization-rules.
However, as this may produce conflicts, users must be warned to only use
this for fallback paths or error-recovery. This is also the reason why the
internal XKB parsers still use the case-sensitive search.
This also adds some test-cases so the expected results are really
produced. The binary-size does _not_ change with this patch. However,
case-sensitive search may be slightly slower with this patch. But this is
barely measurable.
[ran: use bool instead of int for icase, add a recommendation to the
doc, and test a couple "thorny" cases.]

keysym: fix xkb_keysym_is_upper/lower() to work properly
Our current code (taken from the xserver) doesn't handle unicode keysyms
at all, and there seem to be some other changes compared to libX11,
which is what xkbcomp uses. So we just copy the code that does that from
libX11.
It would be much better to not have to hardcode unicode tables like
that, but it's probably better than dealing with glibc locale stuff for
now. It also doesn't affect our binary size much.

Organize src/ and test/ headers
- Add context.h and move context-related functions from xkb-priv.h to
it.
- Move xkb_context definition back to context.c.
- Add keysym.h and move keysym upper/lower/keypad from xkb-priv.h to it.
- Rename xkb-priv.h to map.h since it only contains keymap-related
definitions and declarations now.
- Remove unnecessary includes and some and some other small cleanups.
