Update bitos.h
Add httpValidUriChars to verify the URI only uses chars from the legal URI character set.
Change httpMapFile to allow modules to define the response Tx filename.

Split httpMapFile into httpMapFile and httpMapRequest.

HttpMapFile now takes a char *filename. HttpMapRequest takes a conn and the filename is set from the route and rx->target.
