Subject: [HACKERS] Money integration patches

Here are patches to integrate the money data type. I have included
some math and aggregate functions and have made the locale support optional
by #ifdef USE_LOCALE bracketing of functions.

Modules affected are:
builtins.h.patch
cash.c.patch
cash.h.patch
main.c.patch
pg_aggregate.h.patch
pg_operator.h.patch
pg_proc.h.patch
pg_type.h.patch

I changed the data type to be pass-by-reference rather than by-value
to pave the way for a larger internal representation (64-bit ints?).
Also, I changed the tabbing of cash.c and cash.h to match most of
the other Postgres source code files (4 space indent, 8 spaces == 1 tab).

The locale stuff should be tested under another convention (Russian?)
but I don't know what the correct results should be so perhaps someone
else can give them a try. Will update docs and regression tests in
the next few days.
