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:"
