Overflow detection on chunk extensions

[scunningham]

There's a TODO in the code:

/* just ignore this shit. TODO check for overflow */

Allowing unbounded chunk extensions is hardly the end of the world, but doesn't hurt to address it. Easiest way I found was to treat the state for the chunk headers as if they were regular headers, and have the parser bail if the total amount of data in a chunk header is larger then HTTP_MAX_HEADER_SIZE.

See chunk_ext_overflow

Fix pushed.
