This
1) fixes the vhost changes on master
2) works around the ah pool changes
3) fixes some other build problems that appeared
4) hacks out physical flow control for internal streams
5) updates the advertised protocol to h2 needed by, eg, chrome 51
That gets it able to serve small (<4K, ie, one packet) files over http2

Server support for http[s] as well as ws[s] is implicit.
But until now client only supported ws[s].
This allows the user code to pass an explicit http method
like "GET" in the connect_info, disabling the ws upgrade logic.
Then you can also use lws client as http client, not just ws.

- added options to minilex.c
- regenerated lextable.h
- added WSI_TOKEN_OPTIONS_URI to libwebsockets.h
- tweaked parsers.c to accommodate OPTIONS token
- tweaked server.c to set uri_ptr and uri_len for HTTP callback on OPTIONS as well
Until now minilex has done fine with providing a simple and fast header
decode state machine. But for HTTP2.0, new headers must be added and it
is already on the limit of table branching in 1 byte (already using +0xf8
of a max limit of 0xff).
This changes the minilex format to improve storage size without loss of
decode efficiency. It reduces the curent lws header table from 546 -> 403
bytes and upgrades the ability to increase table size by allowing jumps
to increase from the old limit of +255 states to +65535 states, which should
be enough for anything we ever want to do.
The max number of terminals is also increased from 128 to 2048.

According to RFC2616, all header field names in both HTTP requests and HTTP responses are case-insensitive. But libwebsockets uses a case-sensitive compare.
Reproduce:
Run libwebsockets against a server that sends all of its HTTP header field names in lower-case (for example: https://github.com/extend/cowboy). libwebsockets reports an error. The expected behavior is no errors reported and a successful handshake procedure.
This changes the parser reference table in minilex to all lower case.
The code to walk the parser tables then just forces a tolower on the incoming chars.
This (and minilex tables) only applies to header names.

Clean up minilex
Move the header output to stdout
Introduce lexfile.h as the header output
Use lexfile.h in both minilex itself and lws
Add the following header support
"Accept:",
"If-Modified-Since:",
"Accept-Encoding:",
"Accept-Language:",
"Pragma:",
"Cache-Control:",
"Authorization:",
"Cookie:",
"Content-Type:",
"Date:",
"Range:",
"Referer:"
