Fix problem incorrectly removing COUNTER from PROJECT

There was code in the grammar to check if a COUNTER was used in the
transform of a COUNT PROJECT, and if not report a warning and
convert it to a standard PROJECT.
However the check doesn't work in all cases because it is being
applied to an expression tree that hasn't been normalized.

Move the optimization to hqlopt where the expression tree has
been normalized.

FIX gh-2205 Use logfile creator for roxiePipe logfile

RoxiePipe should use the new component logfile creator to ensure logs
are placed in the correct location. Current code puts them in the wrong
place. Also fixed a problem where the logfile creator was appending '.log'
even when user specified a logfile.

Switch Thor to RoxieMM and use new swapping paradigm

+group/local sort merged
 - group sort now spills
 - an overflowing local sort, used to spill last mem's worth unecessarily
+global sort, either all in mem, or all on disk.
 - refactored out minisort and overflow intercept handling for clarify
+local join, used to spill both sides unconditionally
+globaljoin, each side either all in mem or disk. It still unecessarily
spills first side to disk before gathernig other side (TODO)
+Spillable streams, consuming or shared, retain rows in mem. until need to spill. Used by various things.
+Unified the array classes, will be easier to add spilling elsewhere now, e.g. extend hashdedup.
