Slightly improve LZW_CLEAR handling.
* src/lzw/ftzopen.c (ft_lzwstate_io) <FT_LZW_PHASE_CODE>:
Ensure that subsequent (modulo garbage byte(s)) LZW_CLEAR codes are
handled as clear codes. This also re-sets old_code and old_char to
predictable values, which is a little better than using `random'
ones if the code following LZW_CLEAR is invalid.

Add explicit LZW decompression stack size limit.
Stack larger than 1<<LZW_MAX_BITS is never needed if prefix table is
constructed correctly. It's even less than that, see e.g.
libarchive code comment for a better size upper bound:
http://code.google.com/p/libarchive/source/browse/trunk/libarchive/archive_read_support_filter_compress.c?r=3635#121
This patch adds explicit stack size limit, enforced when stack is
realloced.
An alternative is to ensure that code < state->prefix[code - 256]
when traversing prefix table. Such check is less efficient and
should not be required if prefix table is constructed correctly in
the first place.
* src/lzw/ftzopen.c (ft_lzwstate_stack_grow): Implement it.

Protect against loops in the prefix table.
LZW decompressor did not sufficiently check codes read from the
input LZW stream. A specially-crafted or corrupted input could
create a loop in the prefix table, which leads to memory usage
spikes, as there's no decompression stack size limit.
* src/lzw/ftzopen.c (ft_lzwstate_io) <FT_LZW_PHASE_START>: First
code in valid LZW stream must be 0..255.
<FT_LZW_PHASE_CODE>: In the special KwKwK case, code == free_ent,
code > free_ent is invalid.

* src/bdf/bdflib.c: various improvements to the bdf loader, mainly
used to reduce the amount of heap size required to only test wether
we're dealing with a BDF font (the old code allocated 64 Kb right
before any test).
* src/lzw/ftlzw.c (FT_Stream_OpenLZW): modified the function to check
the LZW header before doing anything else. This helps avoid un-necessary
heap allocations (400 Kb of heap memory for the LZW decoder ! Oh my !)
* src/gzip/ftgzip.c (FT_Stream_OpenGZip): ditto for the .gz decoder,
though the code savings is smaller.
