[Http-crcsync] support for merged tail block (was: Small fix in crcsync.c)

[Alex Wulms]

Hi all,

First of all, the best wishes for 2010.

Secondly, I have pushed a new version of crcsync to the git repo 
(http://repo.or.cz/w/httpd-crcsyncproxy.git). This new version properly 
supports the merged tail block. I have also done some performance 
improvements to the code. The biggest performance improvements is on the 
initialization of the uncrc table(s) and on the CRC validation once the loop 
is in the 'validate-rolling-CRC-for-each-next-byte' phase (which is entered 
as soon as the full block is processed without having found a match yet).

Cheers,
Alex
