[Firebird-devel] Resource tracking

[Samofatov, N. <Nickolay@BroadViewSoftware.com>]

Hi, Daniel, All!

I finished my fixes for improved request resource tracking and committed
them to HEAD.
Basically, I switched resource tracking code to use Firebird container
template classes. Code is (at least should be) functionally equivalent
to what it was before.

As the result for "esystem" test case (i.e. with your real empty
database) memory consumption for each engine process reduced from 280 MB
to 30 MB (9X improvement) and restore times reduced from 7 minutes to 14
seconds (~30X improvement) on my AMD64 box. On Win32 improvements are
the similar, fix is platform-independent. Request compilation timings
also improved accordingly.

The change affects all databases which have complex metadata for example
contain many procedures and triggers.
