MEDIUM: compression: add a distinction between UA- and config- algorithms

Thanks to MSIE/IIS, the "deflate" name is ambigous. According to the RFC
it's a zlib-wrapped deflate stream, but IIS used to send only a raw deflate
stream, which is the only format MSIE understands for "deflate". The other
widely used browsers do support both formats. For this reason some people
prefer to emit a raw deflate stream on "deflate" to serve more users even
it that means violating the standards. Haproxy only follows the standard,
so they cannot do this.

This patch makes it possible to have one algorithm name in the configuration
and another one in the protocol. This will make it possible to have a new
configuration token to add a different algorithm so that users can decide if
they want a raw deflate or the standard one.
