Thanks to autotools happily building stale generated sources, I hadn't
actually ever built my xkbparse.y changes. Fix that so it not only
compiles, but works. This seems to parse long keycodes correctly,
although I very much would not recommend testing this by declaring
0x1fffffff as your highest keycode.

XkbAtomGetString() returns a freshly-allocated string, whereas
XkbAtomText() returns the same in a temporary buffer. XkbAtomText used
to call XkbAtomGetString() and then free the result, which seems quite
spectacularly pointless when you think about it. Shuffle the atom code
around so we don't have to allocate for XkbAtomText().
This changes semantics slightly wrt non-printable characters, but I
haven't been able to see any effect so far. And it may well be ever so
slightly quicker.

The listing code in xkbcomp had been setup to allocate a set of buffers
with file paths and then later parse through them to find which maps were
needed.
All the allocation (with the additional allocation for the components
list) was making it really slow, so this patch makes everything simpler
by just generating the components list as we walk the directory tree.
In xkbcomp, the listing code printed out the xkb files to stdout and the
caller would parse the output. Here, we can just generate a
XkbComponentListPtr and pass it back.
This should be a series of smaller commits, but there was no clean way to
do it since it's basically a complete rewrite except for the core map
matching logic.
A lot of code used for special printing modes in xkbcomp has been
shedded. Callers can massage the output as they please.
This reverts commit c4c9e36fbf. It turns
out that the listing code is used to support the X_kbListComponents
request (via XkbListComponents).
This will have to be refactored into some reasonable interface instead
of the current usage where the server reads xkbcomp stdout. Gross.
Instead of hardcoding the XKB base directory when searching for rules in
the xkbcomp code, we can extend the xkbpath API to cover rules and reuse
it. That will make it more convenient if it's ever exposed so people can
set their XKB search paths in a reasonable way.
We need to support generating a keyboard description from a keymap file
because there are just some cases where RMLVO or ktcsg is not enough.
The map choosing logic has been refactored into its own function and now
supports choosing a named or default keymap.
The noble intention was to expose all the new API and new generic types
in the split out kbproto headers through XKBcommon.h. It turns out that
would be a massive amount of work in the server. Someday, but first just
wedging in XkbCompileKeymap* would be good.
Most of the API is in new internal xkb*.h headers. In order to allow the
XKBcommon.h header to be used from the server, we can't pull in other
headers from kbproto since the server has its own copies. However, types
that are different (XkbDescRec, XkbAction) still have Xkbc equivalents
here, and I think they should be used in the server.
Some of the XkbAction types are defined differently in the server, so we
add those to XKBcommon.h and use them here like XkbcDescPtr. We'll have
to deal with the impedance mismatch on the client side later.
XkbcRF_GetComponents was returning an error but leaving the generated
components alone. This ensures that the broken XkbComponentNamesPtr is
freed and the error is passed up to the caller.
