[Mod-c-users] ehtml session rework

[Gonzalo A. <gon...@gm...>]

Hi,

I've been busy reworking session structure (compiles, but some testing
is still needed).  As it is now:

 * session handling is now in EHTML, mod_c is not aware of session handling.
 * session id are still binary, but handy methods in SessionID class
are provided
    to get it in hexadecimal, urlencoded, and base64encoded.
 * still need to parse Cookie header value (for cookie based sessions).
 * still have to test a little bit the default session driver (this
only suffered cosmetic
    changes).
 * Attached are
   o  Session.h, which includes SessionID, SessionIDDriver (for
session ID generation), SessionDriver (for session data storage).
   o  Dictionary.h (basically a map<string,string>)
   o DefaultSessionDriver.{h,cpp}: this is how default session driver
has been reworked.
   o Plugin.h: as a reference.

Session class provide serialize & marshall methods, whose are used by
the session drivers to store & retrieve session information.

SessionID can be encoded in hex, rfc1728 (urlencoded), or base64.
Should have a default for storing in html forms, urls & Cookie http
header.

I will begin testing this bunch of code.  Any sugestions are more than welcome.

Regards,
