- use the same type (int) for zval.value.usr.len and zval.value.str.len
- use union "zstr" as char*/UChar* mixture instead of void*
- Z_UNISTR() and Z_UNILEN() no longer check for Z_TYPE()
- nuke int32_t from ZE (not finisned)
completely in PS(http_session_vars). This avoids bugs which are caused
by a lack of synchronization between the two hashes. We also don't need
to worry about prioritizing one of them.
Add session.bug_compat_42 and session.bug_compat_warn which are enabled
by default. The logic behind bug_compat_42:
IF bug_compat_42 is on, and
IF register_globals is off, and
IF any value of $_SESSION["key"] is NULL, and
IF there is a global variable $key, then
$_SESSION["key"] is set to $key.
The extension emits this warning once per script, unless told otherwise.
"Your script possibly relies on a session side-effect which existed until
PHP 4.2.3. Please be advised that the session extension does not consider
global variables as a source of data, unless register_globals is enabled.
You can disable this functionality and this warning by setting
session.bug_compat_42 or session.bug_compat_warn.
on the state of $_SESSION/$HTTP_SESSION_VARS. It does not look up
symbols in the global symbol table anymore.
This was achieved by actually planting references between every
$_SESSION["x"] and $x, not only when restoring a session, but also
when registering a session variable (in a register_globals=1 context).
Upon registering a new variable, this memory leak continues to show
up, regardless of register_globals.

Obviously, the newly allocated empty zval is not properly freed. If anyone
has any idea on how to fix that, please step forward.
@ and remove variables from the URL-Rewriter. (thies)
i have also modified the session module to use this - so it doesn't
need to fiddle with the output-system any more
of the session ID string. Default PS_MOD() macro sets this to be the default
creation routine. PS_MOD_SID() macro sets this to a handlers session ID
creation routine.
