Fixed a leak when using automatic output buffering
@ Fixed a leak when using automatic output buffering (Zeev)

Add post request startup handlers. These are called at the end of the
request startup function, and can use the initialized structures like
the symbol table.

configuration failures trap server

Revert my patches to error functions.

Small tweak in the error format.

(php3_log_err): Don't output error message to stderr when
running as CGI binary.

(php_error): finally get rid of those annoying html tags
when running as CGI binary

Use correct data type for mutex.

Implement temporary workaround for thread-safety issues. This
serializes all request accesses. To disable, define NO_GLOBAL_LOCK

i swear, i compiled (at least) before i committed!

"cc -32" on IRIX 6.4 does not like (PHP_TRACK_VARS?"1":"0") - at least not if PHP_TRACK_VARS is 0.

Generalized server-API build process on UNIX. Each SAPI
implementation now has its own directory under sapi/, just like
extensions have theirs under ext/. To make the final targets appear
in the main dir, the top-level Makefile includes sapi/NN/Makefile.inc
from the selected sapi backend. This is a plan Makefile stub without
any autoconf substitutions. Each SAPI backend also has its own
config.m4 like extensions (read at the end of diversion 2) and
config.h.stub files.

Each SAPI backend has to contain:

config.m4: just like for extensions, this file contains
autoconf/automake directives that end up in the configure script. The
only difference is that the sapi config.m4 files are read in diversion
(output block) 2 instead of 3. The sapi config.m4 files should set
two variables: PHP_SAPI (which sapi backend to choose) and SAPI_TARGET
(the name of the resulting library or program, previously BINNAME).
If they are not specified, they will default to "cgi" and "php",
respectively.

Makefile.inc: has to exist, has to define "INSTALL_IT" to the command
used to install the final target (or ":" for no operation). It also
has to define a plain Makefile rule (without autoconf substitutions)
to build $(SAPI_TARGET)

Makefile.am: just what you think. Make sure your target is called
"libphpsapi_NNN.a", where NNN is the value of PHP_SAPI.

Some testing and fixing probably remains. To make everything hang
together, I've done some ugly tricks that I can imagine causing some
problems. I've built and run the CGI version and built the Apache
DSO.

`0' flag ignored with precision specifier and `X' format

- Added support for unknown POST content types (Zeev)
- Introduce the convert_to_*_ex() API in strlen()

That's important enough to be cached

Time to do that - rename the output layer prefix

Use OnUpdateBool for Boolean entries.

Rename allow_builtin_links to expose_php

More cleanup

- Seriously optimize and clean php_parse_gpc_data()
- Added gpc_globals directive to turn global definitions of GPC variables on/off
(untested)

Cleanups & optimizations

A couple of BoundsChecker fixes

fix warning

- Should fix short_tags and co. problem.

- php_error(E_ERROR,...) won't ever return so change the connection_status
before it is called.
