caching of backend issues.

Brief summary:

 - moved http_msg array from cache_response.c to cache_http.c,
   introduced http_StatusMessage() lookup function

 - introduced http_Put{Protocol,Status,Response} to complement
   http_PrintfHeader().

 - introduced SYN_ErrorPage() in a new file, cache_synthetic.c.
   SYN_ErrorPage() populates the session's current object with the
   specified error code and a corresponding HTML error page; it is the
   caller's responsibility to ensure that the session has a suitable
   object (i.e. one that doesn't already have headers or a body)

 - rewrote RES_Error() to simply call SYN_ErrorPage() (with ttl = 0) and
   RES_WriteObj().

 - rewrote cnt_fetch() to use SYN_ErrorPage() to create a 503 page with
   a TTL of 30 seconds when Fetch() fails.

 - removed the call to RES_Error() in cache_backend.c; the error
   trickles back up to cnt_fetch() anyway.

Comments from review:

 - Memory allocation and pointer gymnastics for the header and body
   are duplicated all over the place (in new and pre-existing code)
   and should be centralized and hidden behind a suitable API.

 - The http_*() API needs refactoring, we shouldn't need four
   different functions to manipulate four different entries in the
   same array.

Remove "oknodo" to actually provide an error message if we cannot stop the service.

default anymore, but whatever, it will work with apache httpd out of
the box, and that's better for easy testing) as the backend. sysconfig
file changed to reflect this.

Minor cosmetic changes in the specfile

  * Move user-adjustable parts from init script to defaults file, expect
    $DAEMON_OPTS instead of a whole forest of variables.

  * We have a pid file argument, wheee. :D
