Add an HTTP response bucket type.

Note: this code merely compiles; it doesn't even pretend to work. I'm
simply checking this in now cuz it was sitting around my working copy.

* serf_bucket_types.h: combine the read/parse of the Status-Line into a
    single parsing function returning a structure.

* buckets/respones_buckets.c: initial draft of code to implement the new
    RESPONSE bucket type. it uses a state machine to keep track of what it
    is doing as it reads content from the lower-level bucket [a socket]

* Makefile: compile the new response_buckets.c file
