This patch was originally in pl_exec.c but this file has a 6170 lines
and checking adds 1092 lines - so I moved it to new file

It has little bit different semantics, but it is true, so checking
hardly depends on routines from pl_exec - routines for variable's

I have no problem to move it back. I reduces original patch little bit.

Some refactoring of pl_exec should be nice - a management of row,
record variables and array fields is part that can be shared with
SQL/PSM interpret. But I have not idea how it realize.
