The levels will be resized to the number of levels of the type anyway,
so removing useless levels from the end here is unneeded.

The code that handles group name statements currently does this:
info->group_names[grp - 1 + info->explicit_group] = name;
Other than the fact that this addition makes no sense, it actually can
reach out of the bounds of the array (which is of size XKB_NUM_GROUPS)
in the (non-realistic) case where (grp - 1) is not 0 (i.e. the statement
is not name[Group1] = "foo").
We also change explicit_group to be XKB_LAYOUT_INVALID if not set
otherwise, instead of initializing it to 0; this is clearer and if
someone happens to write 'us:1' for some reason, it will discard the
other groups in the file as it should.
This entire explicit_group thing was clearly bolted on as an
afterthought.

This function really needs a format argument, for symmetry with the
keymap creation functions. If we add new formats, we will almost
certainly want to add support for serializing it into a string. It would
also allow to convert from one format to another, etc.
The in the common case, the user would just want to use the format she
used to create the keymap; for that we add a special
XKB_KEYMAP_USE_ORIGINAL_FORMAT value, which will do that (it is defined
to -1 outside of the enum because I have a feeling we might want to use
0 for something else). To support this we need to keep the format inside
the keymap. While we're at it we also initialize keymap flags properly.
This changes the API, but the old xkb_map_get_as_string name works as
expected so this is the best time to do this.

This is useful to see whether the function was successful and whether
truncation occurred.
It just changes void -> int so shouldn't break API or ABI.

To make it look better and a bit more structured and informative.
Not all of the functions are converted to doxygen format, so this is not
finished.

Simple HTML docs generated from the doxygen comments.
After running 'make' or 'make doc', try firefox doc/html/index.html to
see it (if you have doxygen). It's also installed with 'make install'.
You can use --enable-docs or --disable-docs, or specifically
--with-doxygen or --without-doxygen (autodetected, default yes).
The docs are currently not distributed in the tarball, because I
couldn't make it work properly in all cases :/

This is to follow the general scheme set by all of the other API
functions.
Since no one is using these functions yet, we don't (actually better
not) add the old names to xkbcommon-compat.h.

Before it was a static array of size XKB_NUM_GROUPS.
The previous cleanups made this transition a bit easier. This is a
first step for removing the XKB_NUM_GROUPS hardcoded limit; but for now
we still check that the groups are < XKB_NUM_GROUPS (e.g. in
ResolveGroup and GetGroupIndex) until the keymap, etc. is worked out as
well.
This also makes us alloc quite a bit less (this is just rulescomp):
Before:
==51999== total heap usage: 291,474 allocs, 291,474 frees, 21,458,334 bytes allocated
After:
==31394== total heap usage: 293,595 allocs, 293,595 frees, 18,150,110 bytes allocated
This is because most rmlvo's don't use the full 4 layouts that KeyInfo
had always alloced statically before.

These values weren't wrapped before, which caused group_index_is_active
to stop working after a few group switches.
Also, the current group-wrapping function didn't take into consideration
actions such as LockGroup=-1, which need to wrap around, etc.
xkb_layout_index_t is unsigned, but it was used to hold possibly
negative values (e.g. locked_group is 0 and gets a -1 action).
This group wrapping function should now act like the XkbAdjustGroup
function from xserver, and at least ./test/interactive doesn't bring up
any problems with group switching any more.

Currently, xkb_state_layout_{index,name}_is_active may report multiple
groups as effective, because at looks at base,latched,locked separately.
But there can only be one effective group, which is computed from the
other three. So if XKB_STATE_EFFECTIVE is requested, just compare to the
effective group we have computed.
We also modify mod_{index,name}_is_active similarly, just for symmetry
(there the effective mask is just an OR of the other three so the
current test is correct).

What this code does is, in case someone compile a keymap like -layout
'us,us,us' then only one group would be created. If there is anything
which differentiates between any of the groups (e.g. a variant, another
layout), then this is not done.
This is pretty obscure, only saves a few kbytes in the final keymap, and
if the user asked for it, why not let her?

This old rules parser gives the same kccgst here, so in the interest of
staying compatible we shouldn't fix it there. Similarly we shouldn't
touch ParseIncludeMap, so this is the best place to handle this.

Move xkb_map_* functions to xkb_keymap_*, xkb_key_* functions under
either xkb_keymap or xkb_state, and rename groups to layout in all
user-visible API.
Backwards-compatible hooks are provided, such that old source will
build, but silently mangled to the new names, and old binaries will
also continue to work.

xkblib spec says:
XkbSA_LockNoLock If set, and the action type is XkbSA_LockMods,
the server only unlocks the action modifiers.

The xkblib spec says:
If XkbSA_UseModMapMods is not set in the flags field, the mask,
real_mods, vmods1, and vmods2 fields are used to determine the
action modifiers. Otherwise they are ignored and the modifiers
bound to the key (client map->modmap[keycode]) are used instead.
So we should just assign the modmap without considering what's there.

This change adds range checks based on the lowest keysym and highest keysym in
the table. This allows a quick check to be applied to identify if the keysym
is inside the table.
To really give value to this optimisation the table is split to have a
separate table for the keypad keysyms.
The test suite passes with this change.

Trying ''./test/interactive -l us:5' causes us to crash.
The <layout>:<N> syntax says to put this layout at the N'th level.
However the code (inherited from xkbcomp) doesn't check that the group
is valid, and then happily indexes keyi->groups with it, which has a
static size of XKB_NUM_GROUPS (the SetExplicitGroup function assumes the
index is valid). So any value a user might put there > 4 makes nice
things happen.

e.g. hhhhhHHHHHHHhhhhhh with shift down and up in the middle.
Unfortunately trying a quick test with test/interactive is not possible
because the evdev soft-repeat stops the repeat when another key is
pressed. So you need real soft-repeat for that.

- Add context.h and move context-related functions from xkb-priv.h to
it.
- Move xkb_context definition back to context.c.
- Add keysym.h and move keysym upper/lower/keypad from xkb-priv.h to it.
- Rename xkb-priv.h to map.h since it only contains keymap-related
definitions and declarations now.
- Remove unnecessary includes and some and some other small cleanups.

These statements are pretty pointless for us; we don't restrict keycodes
like X does, and if someone writes e.g. maximum = 255 but only has 100
keys, we currently happily alloc all those empty keys. xkbcomp already
handles the case when these statements aren't given, and uses a computed
min/max instead. We should just always use that.
(Of course since keycodes/evdev currently uses almost all of the
keycodes in the range it declares, including 255, this doesn't save any
memory for the common user right now).
