* Fix 'new object or die' and AiCount issue thoroughly (earlier fix didn't
work with the optimizer).
* Add new macros for standardized definition of classes.
* Only report AiCount problems if shutdown was not silent.
* Fix an AiCount bug - list(...) = $var was using $var multiple times, and thus
causing AiCount to be decreased multiple times even though it was increased only
once for $var. Mark all FETCH_DIM's so that they won't decrease AiCount, and only
decrease AiCount on the last FETCH_DIM.
* Fix a stupid bug - forgot to pass CLS_C to some compiler function. For some reason
MSVC doesn't report these :I
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.
* updated alloc_persist to use critical sections
* changed extension shutdown to two-phase
* updated dependencies
* PR support (don't remember if there was any really)
