Add session.use_cookies option

rename.

Do not try to free NULLs.

- Upgraded var_dump() to take multiple arguments
- php3api_ is changed to php_

Convert module to use Ex API.

add user-level callbacks

Fixed memory leak.

improve short help messages

wddx decode works as well

wddx serialization works now

Since Thies fixed var.c, objects work now, too.

calculate length of cookie string correctly

- Oops

- Make it compile on Win32

Use global symbol table instead..

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

First try at WDDX serializer
(not active currently)

- add global startup/shutdown handlers
- improve genif.sh to also consider all header files for inclusion
(checks for phpext_)
- use vsnprintf in main.c to avoid buffer overflows

Fix lcg.h location.

ext/lcg -> ext/standard in various places

- 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.

return true to match documentation

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