Behdad Esfahbod 6843ce01be Add atomic-pointer functions 
Gonig to use these for lock-free linked-lists, to be used for
hb_language_t among other things.

Behdad Esfahbod 0e253e97af Add a mutex to object header

Behdad Esfahbod bf93b636c4 Remove constructor from hb_prealloced_array_t 
This was causing all object types to be non-POD and have static
initializers.  We don't need that!

Now, most nil objects just moved from .bss to .data.  Fixing for that
coming soon.

Behdad Esfahbod 96a9ef0c9f Remove tab character like other "zero-width" characters 
Uniscribe does that, this make comparing results to Uniscribe

Behdad Esfahbod 0558d55bac Remove hb_atomic_int_set/get() 
We never use them in fact...

I'm just adjusting these as I better understand the requirements of
the code and the guarantees of each operation.

Behdad Esfahbod e4b6d503c5 Don't use atomic ops in hb_cache_t 
We don't care about linearizability, so unprotected int read/write
are enough, no need for expensive memory barriers.  It's a cache,
that's all.

Behdad Esfahbod 303d5850ec Fix Windows atomic get/set 
According to:
http://msdn.microsoft.com/en-us/library/65tt87y8.aspx

MemoryBarrier() is the right macro to protect these, not _ReadBarrier()
and/or _WriteBarrier().

Behdad Esfahbod ed2f1363a3 Fix substitution glyph class propagation 
The old code was doing nothing.

Still got to find an example font+string that makes this matter, but
need this for fixing synthetic GDEF anyway.
