* Plenty of thread safety and Win32 work.
* Changed PHP4 to compile as a DLL, both ISAPI and the the CGI run with the same DLL.
* Switched to using the DLL runtime library under Win32. PHP will NOT work if
compiled against the static library!
* Removed yesterday's php4libts project (with php4dllts, it's obsolete).

This *does* affect thread-unsafe Windows as well - the thread unsafe CGI is also
dependant on the thread-unsafe DLL.

Make GD config fail if it doesn't find the gd files

PHP3 compat stuff

Ok, apxs build works nicely now

oops, the 0th byte should be set, too

final change (?), add get_algorithms_name

make code more compact

remove some redundant code

that was a silly one

add OFB mode, the final one

add mcrypt_create_iv()

Win32 isn't a good os to commit uppercase files with...

cleanup, add new stream mode, allow IV for CBC mode

add get_(key|block)_size

Ah, these too

* Fix a couple of thread safety issues
* Add initial ISAPI support. Very very experimental.
* In the thread safe version, generate php4 as a library so that we can link it with both
php.

* In the thread safe version, generate php4 as a library so that we can link it with both
php.exe and the ISAPI dll. We should probably consider doing that under all circumstances,
under UNIX as well.

The thread-unsafe version *should* be unharmed.

add CBC

add mcrypt module

Ok, this beast compiles via --with-apxs
Not sure if it actually works yet though. I have a feeling there are
some -fpic flags missing in the libzend build. Will test later on
today.

-f tests for plain files only. We need a way to find out whether we could do any damage to existing files. If we cannot write to them, we probably cannot do harmful things hopefully.

serialize & unserialize working (with mem-leak)
