Optimize allocations into uninitialized_zval assignments

- Updates we did today

* Fix all hash checks that checked Bucket.arKey for NULL, when it was changed
to char[1], these checks should have been changed to Bucket.nKeyLength==0
* Support runtime declaration of func

* Fix all hash checks that checked Bucket.arKey for NULL, when it was changed
to char[1], these checks should have been changed to Bucket.nKeyLength==0
* Support runtime declaration of functions. I ended up changing the grammar
to catch top level functions vs. nested functions. The reason is simple -
if we don't have functions properly declared at compile-time, function calls
cannot be resolved at compile time, and have to be resolved at runtime, which
ends up being much much slower (without the optimizer, that is).
It's no biggy though, the grammar change isn't that bad.

Weed out all BoundsChecker-found bugs (including a serious file descriptor leak
in the C++ scanner)

- Don't support interactive mode when thread safe.

* Fix debugger+interactive mode bug
* Recognize whether an extension is with debug information or not

Various thread safety fixes and DLL updates

Cleanups, remove old ts code

Ok, call me crazy, because I probably am.
Thread safe version now uses a C++ scanner object. Works fully.

Make token names uniform, they all begin with T_ now.

Thread safety patch. We're still not quite there but it compiles again, and
more logic has been implemented.

so I returned the one in encaps_var.

- Made INITAL_OP_ARRAY_SIZE smaller (64? can't remeber). I don't think the
erealloc()'s during compile time are such a biggy, we might make it even
smaller. We can have a configure time option as to it's size.
