Changed API: function mg_modify_passwords_file(). Instead of passing context, a domain name is passed, thus making this function completely mongoose-agnostic.

Using volatile keyword in the context struct to prevent unwanted optimization. See http://code.google.com/p/mongoose/issues/detail?id=216

Using STDOUT->autoflush(1) seems to work better than $|=1 - I don't know
why.

Also made the timeout.cgi test a bit more verbose.

Fix issue 180 - make mg_read() handle PUT requests, too. Stop checking for request method in mg_read().

The buffer must skip over consumed_content.

requirements on some projects I work on, where warning levels must be kept
to a minimum.)
