  [pmc] rpa: fix splice shrink fast, add tests

test rpa coverage and add all missing tests
shrink fast has a wrong offset, test splice_shrink_fast()
add tests for resize off empty and resize off move, the 2 fast
  variants with existing offset.
remove shift slow case, this is invalid, add assertion. this is caught
by size == 0 and we cannot have an offset bigger then the threshold.

remove unnedeed pmc/pmc_arrayiterator.h from src/events.c
