Most code in keymap.h is for keycode definitions, while most code in
keymap.c is for the parsing and conversion of keycodes.
The name "keymap" may also make people think these two files are for
mappings, while in fact keycodes are used even when no mappings are
involved, so "keycodes" should be a better file name than "keymap".
assert() is compiled out for release builds, but we don't want to
continue running in these impossible situations.
This also resolves the "implicit fallthrough" warnings for the asserts
in switch cases.
- K_KORIGIN instead of K_KCENTER: This name is similar to what is used
by xev. Alternative could be K_KBEGIN as hinted here:
https://invisible-island.net/xterm/ctlseqs/ctlseqs.html#h2-PC-Style-Function-Keys
But I find Begin and Home too similar, and it might induced some
confusion. The naming looked related to some old keyboard
configuration.
- keymap.c: alias KPPeriod to kDel instead of kPoint.
This might seems weird, but this is actually the behaviour that should
be expected. libtermkey produces "KPPeriod" when num lock is off. To
fix this would need to change this name in termkey.

Note: there are three changes to ascii_isident. Reverting first two (in
find_special_key and first in get_special_key_code) normally fails the new test
with empty &isident, but reverting the third does not. Hence adding `>` to
&isident.
Ref vim/vim#2389.
It also adds support for kExprLexOr which for some reason was forgotten.
It was only made sure that KLEE test compiles in non-KLEE mode, not that
something works or that KLEE is able to run tests.
First stage: something compiling without klee, but with a buch of dirty
hacks - done.
Second stage: something running under klee, able to emit useful results,
but still using dirty hacks - done.
Third stage: make CMake care about clang argumnets - not done, may be
omitted if proves to be too hard. Not that klee can be run on CI in any
case.
