Page cache and temp objects buffer tunable by ServerMode

[basid-irk]

Classic and SuperClassic has per connection page cache (DefaultDbPageCache).
SuperServer and SuperClassic has per database buffer for temp objects (TempCacheLimit).
If change ServerMode, it requires change also DefaultDbPageCache and TempCacheLimit and DPB for (many) aliases in databases.conf.
In addition, page cache for SuperServer must be recalculated into bytes based on page size of concrete database.
All this is inconvenient: the computer calculates, the human thinks. But not.

Suggestion.
Add two (per database) parameter: PageCacheSize (bytes) and TempCacheSize (bytes).
Classic shoud ignore new parameters at all.
SuperClassic should use TempCacheSize parameter value as value for TempCacheLimit and should ignore TCL from conf-files if both defined.
SuperServer should use both – TempCacheSize (as well as SuperClassic) and PageCacheSize and must recalculate PageCacheSize value from conf-files into DefaultDbPageCache before init of database page cache.
Thus, new parameters are "hidden" in runtime and will be used only as source values of the corresponding server parameters.

This premise is completely wrong. There is no difference in cache management between the modes.
