An mlvo can also be used in an expansion, but we didn't mark them in
this case in commit d8a4f52cb9. This caused wrongful warnings on
something like -l ch -v fr -- the `fr` is only added via expansion.

Due to wildcard matches in the rules file, this is only really useful
for misspelled or missing options, e.g.
$ ./test/rmlvo-to-kccgst -o comprose:ralt > /dev/null
xkbcommon: ERROR: Unrecognized RMLVO option "comprose:ralt" was ignored
Although it is more of a warning, it indicates a misconfiguration which
the user probably wants to see. Therefore the log level is ERROR.

Remove the deprecated symbols that were used for ABI compatibility
during the transition period to the first stable version, 0.2.0.
The old *names* can still be used, programs which use the old names will
continue to work, as long as they were compiled against a stable
version (as they have been #defined to the new names from the start; see
xkbcommon/xkbcommon-compat.h). Namely, this will break binaries which:
1. Were compiled against a pre-stable version of libxkbcommon, and
2. Are linked against the next version of libxkbcommon, and
3. Expect to work.
This scenario is very unlikely, and will break in many other ways
anyway. Also, retaining support for these means including them in the
new symbol version file, which I would like to avoid.

Symbol versions provide a means by which ELF utilities can determine
whether a program is incompatible with a too-old library version so
that package management tools can autodetect version-based
dependencies and suggest upgrade paths.

If the keymap doesn't have any key-aliases (which is certainly
possible), the calloc(num_key_aliases, ...) is allowed to return NULL
according to the C standard, but this is not an error.

There is really no reason to deny these tests from different platforms
only for a few #defines.
The only linux-only test (or test program, it is not run by make check)
is interactive-evdev, which actually uses evdev.

libxkbcommon 0.4.3 introduces a new test, x11comp, which does not build
on non-Linux OSes because of the unconditional <linux/input.h> include.
This seems not needed even on Linux, so attached there is a simple patch
to remove it.

If Xvfb is not present, posix_spawn still forks, but the child fails.
In that case, since we left the write fd of the pipe open in the parent,
we just kept waiting on the read() without noticing that the other side
is dead.

Virtual modifiers can have "mappings" to real modifiers, e.g. NumLock
may also set Mod2. In a normal turn of events, the various components
(depressed, latched, locked, and consequently effective) include the
mapped mods, because the masks are pre-resolved everywhere. However,
xkb_state_update_mask() accepts arbitrary mod masks, which may not be
resolved (if it comes from somewhere other than
xkb_state_serialize_mods()). So let's always resolve them ourselves.

It is like test/stringcomp, only instead of using
xkb_keymap_new_from_string(), it uses xkbcomp to upload the keymap to a
dummy Xvfb X server and then xkb_x11_keymap_new_from_device().
If any of these components are not present or fails, the test is shown
as skipped.
The test is messy, fragile, limited and depends on external tools, but I
will improve on that later -- it's better to have a test.

It'd be nicer to use C11's static_assert(), but it's easier to roll our

There can be at most 16 vmods, and we rely on the facts that #vmods +
NUM_REAL_MODS (8) <= XKB_MAX_MODS (32) when accessing keymap->mods.mods.
But msb_pos() can potentially return up to #vmods = 32 if the server is
malicious, so we need to truncate it.

The first 8 modifiers in keymap->mods are the real modifiers; the virtual
modifiers are then at slots 8-24. But XkbGetMap's virtualMods mask
starts the virtual modifiers at zero, so we need to add an offset (like
we do correctly in get_vmod_names()).

With the following two rules:
InterpretDecl : INTERPRET InterpretMatch OBRACE
VarDeclList
CBRACE SEMI
{ $2->def = $4; $$ = $2; }
;
InterpretMatch : KeySym PLUS Expr
{ $$ = InterpCreate($1, $3); }
| KeySym
{ $$ = InterpCreate($1, NULL); }
;
And the fact that InterpCreate doesn't initialize ->def, if the
VarDeclList fails, the %destructor tries to recursively free the
uninitialized ->def VarDef. So always initialize it.
That was the only problematic code in the parser for %destructor (I'm
pretty sure).

If the parser has symbols on the stack, and then enters an error, it
discards the symbols and fails. But their actions which allocate AST
nodes had already ran. So we must free these to avoid leaks.
We use %destructor declarations, see
http://www.gnu.org/software/bison/manual/html_node/Destructor-Decl.html
Note: byacc only supports %destructor when compiled with
--enable-btyacc. Also, it doesn't support using the parse-param in the
destructor. So we might revert this commit before the next release, or
forget about byacc.

We didn't really have any. It also a exposes a memory leak, since the
parser doesn't clean up the AST nodes of the discarded symbols.
