October Month Changes for Firebird 2.5.x Release branch

Here are the source code changes for Firebird 2.5.x branch in the Month of October :
– Fix compilation for semaphore classes [57221]
– Backport fix for CORE-3946 – UNICODE collations does not work with ICU 49 [57236]
– Fixed the backporting bug introduced while fixing CORE-3902 [57244]
– Avoid a sweep pass for temporary tables, as the sweeper always sees those tables as empty, but even setting them up as empty has a non-zero cost [57265]
