Including the X server is a bit of a borderline case; we should mostly
encourage people to use update_mask() only when xkbcommon itself
serializes the state on the other side. But it's not entirely wrong
either.. So rephrase a bit.

This is too strict, and causes symbols/cz to fail parsing. Instead, just
emit a warning (not shown by default):

We should handle empty xkb_keycode and xkb_symbol sections, since
xkbcomp handles them, and apparently XQuartz uses it. There are also
files for it in xkeyboard-config (rules=base model=empty layout=empty,
which translate to keycodes/empty and symbols/empty).

The file src/xkbcomp/action.c already doesn't handle this action type
and fails if it encounters it. So lets not pretend to do something with
it, and ignore it rather than failing.
If we/someone wants this we can consider implementing it.

Which to choose: xkb_state_update_key() / xkb_state_update_mask(). If you
use update_mask(), you don't (and shouldn't) use update_key().
If you use update_key(), be careful not to have unmatched UP/DOWN
calls; this can bring about stuck modifiers etc.
Probably want to use XKB_STATE_{MODS,LAYOUT}_EFFECTIVE. The others are
only useful in very special cases.

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

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

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.
