[multiple] http_method_buf()

Browse Source 
- http_method_buf() returns (const buffer *)
- comment out unused get_http_status_name()
- inline func for http_append_method()

config processing requires a persistent buffer for method on the
off-chance that the config performed a capturing regex match in
$HTTP["method"] condition and used it later (e.g. in mod_rewrite)
(Prior behavior using r->tmp_buf was undefined in this case)
