wddx serialization works now

update macro

add transparent session id propagation
this uses a custom scanner which detects relative URIs and changes
them appropiately.
must be explicitly enabled with --enable-trans-sid

(normal case is not affected, since session_adapt_uris defaults to
void statement. Compiler should eliminate dead code in output.c then.)

- Added session_unset() function
- Fixed double session globals shutdown crash
- Added warning when session_destroy() is called without session_start()

- support for external entropy sources
- extern_referer_chk => extern_referer_check
- kill a warning in mod_files.c

remove superflicious enumaration

- fix potential buffer problem in send_cookie
- fix gc probability algorithm
- don't access mod_data directly
- initial version of mm support for session data storage

This work

- fix potential buffer problem in send_cookie
- fix gc probability algorithm
- don't access mod_data directly
- initial version of mm support for session data storage

This works pretty good, but we need to create the initial mm pool
from the parent process/thread. Still looking for a clean way to do that.

- add session.extern_referer_chk
- use combined lcg in session id creation

we don't need php_sid

that should be included 1st

implement a simple API in the case someone wants to define his/her own serialization stuff

Added session expiration.

Added session_is_registered(varname) function.

* Fix a buglet in the session module
* Make some renames in the session module - avoid having a function called 'delete'
so that we don't piss any C++ compilers. Also rename the {startup,s

* Make some renames in the session module - avoid having a function called 'delete'
so that we don't piss any C++ compilers. Also rename the {startup,shutdown}_globals
to {startup,shutdown}_session_globals, so that they're a bit less general names,
and made them static.
* Remove uselss variables
