PATH_MAX is optional in POSIX, so avoid its unconditional usage
allocating and freeing buffers as needed.
To avoid too many malloc/free in the for loop in FindFileInXkbPath,
a buffer is grown according to the size needed at each iteration.
Needed for some tests. The tests need some adjustment, mostly because of
the resolution of xkeyboard-config bug

Also add the 'ch' symbols file for future tests.

xkb_atom_intern now takes a len parameter. Turns out though that almost
all of our xkb_atom_intern calls are called on string literals, the
length of which we know statically. So we add a macro to micro-optimize
this case.

This ensures the names are escaped before having any interaction with
the user.
This was caught by noticing dump(compile(dump())) != dump. Since that's
a nice test we add it to stringcomp.

Add three new pieces of API:
- xkb_keymap_min_keycode does what it says on the tin
- xkb_keymap_max_keycode likewise
- xkb_keymap_key_for_each calls the provided function once for every
valid key in the keymap

If the keycode range is smaller than 8 → 255, artifically widen it when
dumping the keymap as not to displease X.

The scanner is very similar in structure to the one in xkbcomp/rules.c.
It avoids copying and has nicer error reporting.
It uses gperf to generate a hashtable for the keywords, which gives a
nice speed boost (compared to the naive strcasecmp method at least). But
since there's hardly a reason to regenerate it every time and require
people to install gperf, the output (keywords.c) is added here as well.
Here are some stats from test/rulescomp:
Before:
compiled 1000 keymaps in 4.052939625s
==22063== total heap usage: 101,101 allocs, 101,101 frees, 11,840,834 bytes allocated
After:
compiled 1000 keymaps in 3.519665434s
==26505== total heap usage: 99,945 allocs, 99,945 frees, 7,033,608 bytes allocated

This wraps the current mmap call and adds a fallback implementation for
systems which do not have mmap (e.g. mingw).
Signed-off-by: Ran Benita <ran234@gmail.com>
The current API doesn't allow the caller to create keymaps from mmap()'ed
files. The problem is, xkb_keymap_new_from_string() requires a terminating
0 byte. However, there is no way to guarantee that when using mmap() so a
user currently has to copy the whole file just to get the terminating zero
byte (assuming they cannot use xkb_keymap_new_from_file()).
This adds a new entry xkb_keymap_new_from_buffer() which takes a memory
location and the buffer size in bytes.
Internally, we depend on yy_scan_{string,byte}() helpers. According to
flex documentation these already copy the input string because they are
wrappers around yy_scan_buffer().
yy_scan_buffer() on the other hand has some insane requirements. The
buffer must be writeable and the last two bytes must be ASCII-NUL. But the
buffer may contain other 0 bytes just fine.
Because we don't want these constraints in our public API,
xkb_keymap_new_from_buffer() needs to create a copy of the input memory.
But it then calls yy_scan_buffer() directly. Hence, we have the same
number of buffer-copies as with *_from_string() but without the
terminating 0 requirement.
The explicit yy_scan_buffer() call is preferred over yy_scan_byte() so the
buffer-copy operation is not hidden somewhere in flex.
Maybe some day we no longer depend on flex and can have a zero-copy API. A
user could mmap() a file and it would get parsed right from this buffer.
But until then, we shouldn't expose this limitation in the API but instead
provide an API that some day can work with zero-copy.

The doxygen page looked a bit dead, the README fills it nicely, and is
already written in the markdown format which doxygen uses (I think?).
Unfortunately the USE_MDFILE_AS_MAINPAGE doxygen config doesn't seem to
do anything.. So we just add a {#mainpage} tag at the top of the README
which isn't so bad. BUT we still need some config option (the
no_extension=md part) so that doxygen will accept README instead of
README.md or somesuch. And that requires an even newer release, 1.8.3.1,
released 2013-01. But if an older version is used, it doesn't spew out
warnings but just skips the README, which is fine.

We want to use the USE_MDFILE_AS_MAINPAGE option which was introduced in
doxygen 1.8.3 (released 2012-12).

these these warnings, which can be ignored:

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.
