keysym: use a perfect hash function for case sensitive xkb_keysym_from_name
In 7d84809fdccbb5898d0838849ec7c321410182d5 I added a fast path for the
case-sensitive case, but it is still slowing down Compose parsing.
Instead of the binary search, use a perfect hash function, computed with
a simple python module I found (vendored).
It is faster -- perf diff is:
Baseline Delta Abs Shared Object Symbol
........ ......... ................. ...................................
22.35% -14.04% libc-2.33.so [.] __strcmp_avx2
16.75% +10.28% bench-compose [.] xkb_keysym_from_name
20.72% +2.40% bench-compose [.] parse.constprop.0
2.29% -1.97% bench-compose [.] strcmp@plt
2.56% +1.81% bench-compose [.] resolve_name
2.37% +0.92% libc-2.33.so [.] __GI_____strtoull_l_internal
26.19% -0.63% bench-compose [.] lex
1.45% +0.56% libc-2.33.so [.] __memchr_avx2
1.13% -0.31% libc-2.33.so [.] __strcpy_avx2
Also reduces the binary size:
Before:
text data bss dec hex filename
341111 5064 8 346183 54847 build/libxkbcommon.so.0.0.0
After:
text data bss dec hex filename
330215 5064 8 335287 51db7 build/libxkbcommon.so.0.0.0
Note however that it's still larger than before 7d84809fdccbb5898d08388:
text data bss dec hex filename
320617 5168 8 325793 4f8a1 build/libxkbcommon.so.0.0.0

keysym: fast path for case sensitive xkb_keysym_from_name
xkb_keysym_from_name() is called a lot in Compose file parsing. The
lower case handling slows things down a lot (particularly given we can't
use the optimized strcasecmp() due to locale issues). So add separate
handling for the non-case-sensitive case which is used by Compose.
To do this we need to add another version of the ks_tables table. This
adds ~20kb to the shared library binary. We can probably do something
better here but I think it's fine.

Commit and distribute ks_tables.h
The ks_tables.h file is generated by makekeys.py from
xkbcommon-keysyms.h, which in turn is generated initially by 'make
update-keysyms'. The xkbcommon-keysyms.h file is commited to git and
distributed in the tarball. Since ks_tables.h should only ever change
when xkbcommon-keysyms.h changes, it is more sensible to update them
together and treat them the same, instead of generating ks_tables.h
every time for every builder with 'make', as we do now.
This means we don't need python as a build dependency (only the one
running update-keysyms, i.e. no one, needs this), and we can be
sure exactly the same file is used by everyone. We also don't need to
run makekeys.py on every build.
