Add a simple Pools Limiter. (#1830)
* Added support for offline invalidation, via PPTC, of low cq translations replaced by high cq translations; both on a single run and between runs. Added invalidation of .cache files in the event of reuse on a different user operating system. Added .info and .cache files invalidation in case of a failed stream decompression. Nits. * InternalVersion = 1712; * Nits. * Address comment. * Get rid of BinaryFormatter. Nits. * Move Ptc.LoadTranslations(). Nits. * Nits. * Fixed corner cases (in case backup copies have to be used). Added save logs. * Not core fixes. * Complement to the previous commit. Added load logs. Removed BinaryFormatter leftovers. * Add LoadTranslations log. * Nits. * Removed the search and management of LowCq overlapping functions. * Final increment of .info and .cache flags. * Nit. * Free up memory allocated by Pools during any PPTC translations at boot time. * Nit due to rebase. * Add a simple Pools Limiter. * Nits. * Fix missing JumpTable.RegisterFunction() due to rebase. Clear MemoryStreams as soon as possible, when they are no longer needed. * Code cleaning. * Nit for retrigger Checks. * Update Ptc.cs * Contextual refactoring of Translator. Ignore resetting of pools for DirectCallStubs. * Nit for retrigger Checks.
