REORG: http: move some very http1-specific parts to h1.{c,h}
Certain types and enums are very specific to the HTTP/1 parser, and we'll
need to share them with the HTTP/2 to HTTP/1 translation code. Let's move
them to h1.c/h1.h. Those with very few occurrences or only used locally
were renamed to explicitly mention the relevant HTTP version :
enum ht_state -> h1_state.
http_msg_state_str -> h1_msg_state_str
HTTP_FLG_* -> H1_FLG_*
http_char_classes -> h1_char_classes
Others like HTTP_IS_*, HTTP_MSG_* are left to be done later.
