Canonicalises two sets of components (new and old), e.g.:
new: +bar
old: foo
result: foo+bar
This is required as part of the spec, so clients can reuse part of the
device's old keymap.

Ensure that Unicode string representations are accepted and turned into
numbers, as well as hexadecimal numbers in 0xabcd1234 form; unknown
keysyms are output as 0xabcd1234 in string form.
This also ensures that strings are never returned malloc()ed.

Add NoSymbol into the keysym table, so keysym <-> string conversion works for
that, too; also eliminate special-casing of VoidSymbol.
This will require special-casing in libX11 to preserve its API.

filecomp would fail because it couldn't find the input files, after
compilation failed due to missing includes.

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.
Instead of requiring the user to call XkbInitIncludePath() and
XkbAddDefaultDirectoriesToPath(), all the path entry points now implicitly
initialize the path. When initializing, the default directories are added
so it's useful.
This provides normal operation without exposing the xkbpath API. That
might happen later to allow apps to edit the XKB search path.
Added a test program, rulescomp, which takes a RMLVO set and generates a
XkbcDescPtr. This is essentially what the xserver will do, except that we
still need to access some xkbcomp internal API to make it work.
