[PATCH] mod_disk_cache, only cache req_hdrs if vary

Some more low hanging fruit.

This moves varray into disk_cache_object_t and only writes out/reads in 
  the request headers if the response actually varied.

An easy 4-7% performance boost in my tests for responses with no vary.

An improvement upon the earlier patch that only stores the request 
headers that are involved in vary.
