Enable chroot() only if SAPI is CGI.

- Don't wrap lines... this is annoying while coding.

Merge RAND_REDESIGN into MAIN

@- Added ini_get_all() function which returns all registered ini entries
or the entries for the specified extension. (Jani)

According to Zeev this code is just for showing how to create overloaded classes.

WS fixes and indenting.

Make the session module more independent

Get rid of TRANS_SID - it's always possible to use it now.

Move the trans-sid mechanism to use the output buffering mechanism.
Advantages:
- Would work with the output buffering mechanism in general, and with
output compression in particular

Advantages:
- Would work with the output buffering mechanism in general, and with
output compression in particular
- Should yield better performance (untested as of yet)

Fix build

Track down a few more functions that don't check for 0 args and use
faster mechanism

We don't consistently check for args passed to functions that don't
take any args. In some cases we probably want to skip the check for
performance reasons, but in other cases where performa

We don't consistently check for args passed to functions that don't
take any args. In some cases we probably want to skip the check for
performance reasons, but in other cases where performance is unlikely
to be a factor, not throwing a warning on the wrong number of args passed
to a function is at best inconsistent, and at worst it could hide a bug.
So, add a few such checks. There are still lots of cases out there.

Whitespace

Implement import_request_variables()

@- Added vprintf() and vsprintf() functions that allow passing all arguments
@ after format as an array. (Andrei)

we can no longer register internal-classes once the script is started.
therefore the "incomplete class" is now registered at MINIT time.

some more eliminate-fetches-or-escalate-them-at-least

- TSRMLS_FETCH work
- whitespace fixes

fix possible crash - we should never keep the zval** as they might point
somewhere into the Engine. (there's still a new bug in strtok - hunting;-)

Don't copy the strtok parameter

Replace our strtok implementation with a binary-safe one which code
does not cause headaches when reading it. Also happens to be a bit quicker.

These new math functions are not supported on Win32

- Added a few new math functions from Jesus Castagnetto.
- Converted to Z_* macros.
@- Added a few new math functions. (Jesus)
