The file_id thing is used to identify the XkbFile some statement
originally came from. This is needed to avoid spurious warnings; for
example, if you write the same alias twice in a file, that's redundant,
and you'd want a warning about it. However if intentionally override it
from another file, that's fine, and you shouldn't get a warning. So by
comparing the file_id's the needed log verbosity is changed.
However, the file_id mechanism is really not needed, because we already
have that info! Each KeyNamesInfo corresponds to one XkbFile, so if the
conflict occurred while handling that one file -> same_file = true, and
if it occurs while merging two Info's -> same_file = false.

If 'into' in empty we can just steal 'from'.
Also move the alias-merging into the big function, it's nicer this way.

This is already checked when adding a new alias and merging aliases, so
it can never happen when we get to copying to the keymap.
Also the log verbosity decision there is quite useless, we should just
warn always and be done with it. So we can remove the file_id from
AliasInfo, and collapse the alias functions together.

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.

Some tests use linux/input.h (and epoll), but we're building on some
other kernels (e.g. debian freebsd). We could just copy the file but
it's GPL. We could also skip the tests (exit code 77) but it doesn't
really matter.

Make it a bit easier to experiment with other formats.
Add a struct xkb_keymap_format_operations, which currently contains the
keymap compilation and _get_as_string functions. Each format can
implement whatever it wants from these.
The current public entry points become wrappers which do some error
reporting, allocation etc., and calling to the specific format. The
wrappers are all moved to src/keymap.c, so there are no XKB_EXPORT's
under src/xkbcomp/ anymore.
The only format available now is normal text_v1.
This is all not very KISS, and adds some indirection, but it is helpful
and somewhat cleaner.

The snprintf trick that LedStateText and ControlMaskText do cannot work,
because you can't use the buffer as an argument to write to itself!
(posix at least has 'restrict' there). So those two actually never
worked for more than one value (i.e. with a +).
Fix that, and do the same cleanup to ModMaskText. Now we have 3
functions which look exactly the same, oh well.
Also increase the context text buffer size, you never know.

xkbcomp doesn't indent there, so it's easier to diff.
Also saves some horizontal space which is sorely needed when looking at
these files (especially the xkb_symbols).

"Value stored to 'stmt' is never read"
"Value stored to 'grp_to_use' is never read"
And change 'grp' to 'group' if we're here.

The code currently uses the two names interchangeably.
Settle on 'led', because it is shorter, more recognizable, and what we
use in our API (though of course the parser still uses 'indicator').
In camel case we make it 'Led'.
We change 'xkb_indicator_map' to just 'xkb_led' and the variables of
this type are 'led'. This mimics 'xkb_key' and 'key'.
IndicatorNameInfo and LEDInfo are changed to 'LedNameInfo' and
'LedInfo', and the variables are 'ledi' (like 'keyi' etc.). This is
instead of 'ii' and 'im'.
This might make a few places a bit confusing, but less than before I
think. It's also shorter.

Recent xkeyboard-config introduced the following line in symbols/level3:
vmods = LevelThree,
However, the XKM format which xkbcomp produces for the X server can't
handle explicit virtual modifiers such as this:
https://bugs.freedesktop.org/show_bug.cgi?id=4927
So by doing the following, for example:
setxkbmap -layout de (or another 3-level layouts)
xkbcomp $DISPLAY out.xkb
xkbcomp out.xkb $DISPLAY
The modifier is lost and can't be used for switching to Level3 (see the
included test).
We, however, are affected worse by this bug when we load the out.xkb
keymap. First, the FOUR_LEVEL_ALPHABETIC key type has these entries:
map[None] = Level1;
map[Shift] = Level2;
map[Lock] = Level2;
map[LevelThree] = Level3;
[...]
Now, because the LevelThree virtual modifier is not bound to anything,
the effective mask of the "map[LevelThree]" entry is just 0. So when
the modifier state is empty (initial state), this entry is chosen, and
we get Level3, instead of failing to match any entry and getting the
default Level1.
The difference in behavior from the xserver stems from this commit:
acdad6058d
Which removed the entry->active field. Without bugs, this would be
correct; however, it seems in this case we should just follow the
server's behavior.
The server sets the entry->active field like so in XKBMisc.c:
/* entry is active if vmods are bound */
entry->active = (mask != 0);
The xkblib spec explains this field, but does not specify how to
initialize it. This commit does the same as above but more directly.

Sync the files again from xkeyboard-config 2.8, since there have been
some changes we should test against.
Also added a script test/data/sync.sh if we want to do it again in the
future.
