Improve macro definition in order to avoid potential precedence issues.

For example, sparse spotted that the following line was spurious:
        newcond->flags &= ~CONDFLAG_NOCASE;
It this particular case, 2 bits were resetted (instead of only 1). This was harmless because the first bit (i.e. CONDFLAG_NONE) is never tested as-is.

With the current implementation, it is likely to connect/close a socket with the memcache server for each command sent.
The root cause is a too small idle timeout (600 microseconds).

Add a new directive, 'MemcacheConnTTL',  to control this idle connection timeout with the memcache server(s).
Change the default value from 600 usec (!) to 15 sec as per Yann suggestion.

I've limited accepted values from 1 to 1800 seconds (half an hour) because internaly, the value passed to 'apr_memcache_server_create' is still in mirco-seconds.

* Give ap_proxy_post_request as chance to act correctly on the status code
  by setting r->status temporarily to access_status. r->status might be
  different than access_status e.g. r->status could be HTTP_OK if e.g. we
  override the error page on the proxy or if the error was not generated
  by the backend itself but by the proxy e.g. a bad gateway.
