[PATCH] Add PCRE support

[Adrian Otto]

DES,

I suggest making it an optional ./configure option. That way you could  
still build it the old way if you wanted. From my perspective the  
value of the feature would justify having two regex implementations in  
varnish. Make the default the current one. You can tell by looking at  
the patch that regex is not used extensively anyway so it's not likely  
to matter much. It's not a lot of different code.
