[PATCH] new header buflen

[Jason Gloudon]

The buflen of a new header was not always set to 0, which would cause SIGSEGVs
when parrot_reallocate tries to copy a non-zero length buffer with a bufstart
of NULL. This would happen when buffers get recycled.

I don't know if new_pmc_header has the same problem, but it also does not
initialize the buffer length.
