test: add keycodes files which map directly to evdev codes

This is a proof-of-concept for the long key names. The keycodes in the
file evdev-xkbcommon are autogenerated from linux/input.h, and uses the
names given there; all of the previous names are aliased to the new
names, so they continue to work with the symbols files, etc.

You can try it with 'sudo ./test/interactive -r evdev-xkbcommon -n 0'
The -n 0 means that we don't offset the evdev scan codes - just feed
them directly. The -r evdev-xkbcommon just means to use a new rules file
which makes us use the new keycodes file. (The only problem I can see is

Don't limit key names to 4 characters

Currently you can't give a key in xkb_keycodes a name of more than
XKB_KEY_NAME_LENGTH (= 4) chars. This is a pretty annoying and arbitrary
limitation; it leads to names such as <RTSH>, <COMP>, <PRSC>, <KPAD>
etc. which may be hard to decipher, and makes it impossible to give
more standard names (e.g. from linux/input.h) to keycodes.

The purpose of this, as far as I can tell, was to save memory and to
allow encoding a key name directly to a 32 bit value (unsigned long it
was).

We remove this limitation by just storing the names as atoms; this lifts
the limit, allows for easy comparison like the unsigned long thing, and
doesn't use more memory than previous solution. It also relieves us from
doing all of the annoying conversions to/from long.

This has a large diffstat only because KeyNameText, which is used a lot,
now needs to take the context in order to resolve the atom.

    sudo ./test/interactive -l ru,us -v
the first group doesn't get any syms for the main keys.

The problem (Clearly the fix above is useless):

The ru(phonetic) map is specified using aliases, e.g. LatQ, LatW instead
of AD01, AD02, etc. When combined with another layout which uses the
real names (AD01, AD02), the symbols code should recognize they are the
same key and merge them into one KeyInfo. The current code does that,
but it doesn't catch the case where the alias was processes *before* the
real one; so we get two KeyInfo's and the later one wins. So e.g. the
ru(phonetic) symbols are ignored.

The fix:

Before adding a new KeyInfo to the keys array, always replace its name
by the real name, which avoids the entire issue. Luckily this is done
pretty late so most error messages should still show the alias name.

12 years agosymbols: remove mention of keycodes in CopySymbolsDef

symbols: remove mention of keycodes in CopySymbolsDef

Since now we only use the keycode in this function for logging, it's
better not to mention the keycode at all because the XkbKeyGetKeycode
macro is implemented using a dirty hack 0_0
The key name is sufficient to determine uniquely where to look.

This function does some funky stuff, which, as far as I can tell, was
needed to support the functionality of giving different keycodes the
same name and thus make them duplicates (MERGE_ALT_FORM). This stuff was
removed as useless in 0765064b3, but this leftover wasn't noticed.

symbols: add LevelInfo

Add a LevelInfo to hold a single array of level specific info inside
a GroupInfo, instead of keeping the acts, symsMapIndex and
symsMapNumEntries arrays and the numLevels field separate and in sync.
This simplifies the code, and goes a long way toward making  the
key-merging code somewhat understandable. Also uses less memory.

Note that the syms array is still in GroupInfo for now, with the levels
holding offsets into it.

GroupInfo keeps all of the info for a specific group in one struct.
