Prevent recursive includes of keymap components
- Add check for recursive includes of keymap components. It relies on
limiting the include depth. The threshold is currently to 15, which
seems reasonable with plenty of margin for keymaps in the wild.
- Add corresponding new log message `recursive-include`.
- Add tests for recursive includes.

Fix memory leaks in key types compilation
When there is no error the types are “stolen” and copied to the keymap.
But when there is an error, `MergeIncludedKeyTypes` just return without
“stealing” nor freeing the types.
Fixed by explicitly freeing the key types.
Fixed another leak in `HandleKeyTypeDef` that may occur if there is an
error in parsing a type definition.

Messages: merge macros with and without message code
Previously we had two types of macros for logging: with and without
message code. They were intended to be merged afterwards.
The idea is to use a special code – `XKB_LOG_MESSAGE_NO_ID = 0` – that
should *not* be displayed. But we would like to avoid checking this
special code at run time. This is achieved using macro tricks; they
are detailed in the code (see: `PREPEND_MESSAGE_ID`).
Now it is also easier to spot the remaining undocumented log entries:
just search `XKB_LOG_MESSAGE_NO_ID`.

Structured log messages with a message registry
Currently there is little structure in the log messages, making
difficult to use them for the following use cases:
- A user looking for help about a log message: the user probably
uses a search engine, thus the results will depend on the proper
indexing of our documentation and the various forums. It relies
only on the wording of the message, which may change with time.
- A user wants to filter the logs resulting of the use of one of the
components of xkbcommon. A typical example would be testing
xkeyboard-config against libxkbcommon. It requires the use of a
pattern (simple words detection or regex). The issue is that the
pattern may become silently out-of-sync with xkbcommon.
A common practice (e.g. in compilers) is to assign unique error codes
to reference theses messages, along with an error index for
documentation.
Thus this commit implements the following features:
- Create a message registry (message-registry.yaml) that defines the
log messages produced by xkbcommon. This is a simple YAML file that
provides, for each message:
- A unique numeric code as a short identifier. It is used in the
output message and thus can be easily be filtered to spot errors
or searched in the internet. It must not change: if the
semantics of message changes, it is better to introduce a new
message for clarity.
- A unique text identifier, meant for two uses:
1. Generate constants dealing with log information in our code
base.
2. Generate human-friendly names for the documentation.
- A type: currently warning or error. Used to prefix the constants
(see hereinabove) and for basic classification in documentation.
- A short description, used as concise and mandatory documentation.
- An optionnal detailed description.
- Optional examples, intended to help the user to fix issues
themself.
- Version of xkbcommon it was added. For old entries this often
unknown, so they will default to 1.0.0.
- Version of xkbcommon it was removed (optional)
No entry should ever be deleted from this index, even if the message
is not used anymore: it ensures we have unique identifiers along the
history of xkbcommon, and that users can refer to the documentation
even for older versions.
- Add the script update-message-registry.py to generate the following
files:
- messages.h: message code enumeration for the messages currently
used in the code base. Currently a private API.
- message.registry.md: the error index documentation page.
- Modify the logging functions to use structured messages. This is a
work in progress.

keymap: fix NULL dereference when dumping the default fallback type
The default fallback type uses
type->level_names = NULL
but the keymap-dump code was not checking this case.
Instead of adding more workarounds and possible bugs (e.g. previous
commit), let's just keep the number of level names separately. This has
the additional advantage retains extraneous level name if someone adds
them for some reason.

xkbcomp/types: fix types being assigned the wrong number of levels in some circumstances
The buggy code assigned the number of levels based on the number of
level names in the definition, instead of the actual number of levels!
This would completely break type definitions which do not give names to
levels.
This was not noticed for so long because xkeyboard-config always gives
names to all levels.
This regressed in 61fed8dab9b8e27981f36ffc96666d7376546e30.

keymap: don't use darray in xkb_mod_set
Instead just statically allocate the mods array (of size MAX_MOD_SIZE =

(nicer code, no OOM, etc.). It's also small and dense enough.

This is the only place where the modifier information is modified. We

types: separate ctx
Separate the ctx object to its own field in CompatInfo, instead of doing
keymap->ctx.
The compilation functions should not have direct access to the keymap;
instead they should process the files with their own independent state
(in the *Info structs) as much as possible, and only at the end should
they be copied (i.e. commited) to the keymap. If the compilation fails,
it leaves no by-products. It's also just good form.
This was seemingly the original author's intention, but I suppose he cut
a few corners (mostly with the handling of virtual modifiers, which are
threaded through types -> compat -> symbols).
This commit is the first step and may look artificial; however the
'keymap' field will be removed shortly.

vmod: bring back support for direct vmod -> real mod mapping
This brings back the functionality that was removed in
b9c87eb710ba4a86455601ca8c5a516b25e20366. Though it is not used in
xkeyboard-config, from our current perspective it can be quite useful to
be able to set the mappings directly, thus sidestepping the ugly and
legacy-ridden modifier_map statement.
Here's an example of how to get rid of modifier_map statements (though
that would break core-X11 applications, since they must have the
mappings through keysyms):
virtual_modifiers NumLock = Mod2;
virtual_modifiers Alt = Mod1;
// Would be nice to map these to Alt, but that would be
// incompatible with xkbcomp and somewhat complicated
virtual_modifiers LAlt = Mod1;
virtual_modifiers RAlt = Mod1;
virtual_modifiers LevelThree = Mod5;
virtual_modifiers RControl = Control;
virtual_modifiers LControl = Control;
virtual_modifiers Super = Mod4;
virtual_modifiers Meta = Mod1;
virtual_modifiers Hyper = Mod4;
virtual_modifiers AltGr = Mod5;
virtual_modifiers LShift = Shift;
virtual_modifiers RShift = Shift;

xkbcomp: handle XKB file include's better
The 'merge_mode' situation is quite messy, and we've introduced a
regression compared to original xkbcomp: when handling a composite
include statement, such as
replace "foo(bar)+baz(bla)|doo:dee"
and merging the entire resulting *Info back into the including *Info,
we actually use the merge mode that is set by the last part (here it is
"augment" because of the '|'), when we should be using the one set for
the whole statement (here "replace").
We also take the opportunity to clean up a bit.

Remove now-unneeded mod type annotations
Most of the mod type annotations can now be changed to MOD_BOTH, because
if you pass a mask which can only contain real mods in the first place to
e.g. ModMaskText, then MOD_REAL and MOD_BOTH will give the same result.
In the cases where MOD_BOTH is only ever the argument, we just remove
it. What's left is where it really "matters".

Remove VModInfo for now
VModInfo currently is only used to track which virtual modifiers were
declared in the file which owns the VModInfo. This, in turn, is only
used in ResolveVirtualModifier, which in turn is only used to resolve
the virtualModifier field in an interpret statement (compat.c). In other
words, it is used to ensure that interprets can only use a vmod which
was declared in the same map.
We remove this now, because it doesn't do much and distracts from other
changes; we will later re-add it properly. Specificly, we will make it
so that virtual modifiers are not the exception in that they modify the
keymap directly, instead of keeping the changes in some *Info struct and
commiting them to the keymap at the end of the compilation. (This is bad
because if a vmod is added to the keymap, and then the compilation of
this specific file fails, the change sticks around nonetheless).

Organize xkbcomp/ header files
Various non-functional changes:
- Re-add keycodes.h and move some stuff there.
- Add parser-priv.h for internal bison/flex stuff.
- Don't include headers from other headers, such that file dependencies
are immediate in each file.
- Rename xkbcomp.h -> ast.h, parseutils.{c,h} -> ast-build.{c,h}
- Rename path.{c,h} -> include.{c,h}
- Rename keytypes.c -> types.c
- Make the naming of XkbFile-related functions more consistent.
- Move xkb_map_{new,ref,unref} to map.c.
- Remove most extern keyword from function declarations, it's just
noise (XKB_EXPORT is what's important here).
- Append XKBCOMP_ to include guards.
- Shuffle some code around to make all of this work.
Splitting this would be a headache..
