Extend numeric_round and numeric_trunc to accept negative scale inputs
...
(ie, allow rounding to occur at a digit position left of the decimal
point). Apparently this is how Oracle handles it, and there are
precedents in other programming languages as well.

Add numeric <-> int8 and numeric <-> int2 conversion functions, as well
...
as a unary minus operator for numeric. Now that long numeric constants
will get converted to NUMERIC in early parsing, it's essential to have
numeric->int8 conversion to avoid 'can't convert' errors on undecorated
int8 constants. Threw in the rest for completeness while I was in the
area.
I did not force an initdb for this, since the system will still run
without the new pg_proc/pg_operator entries. Possibly I should've.

Fix bugs in NUMERIC ceil() and floor() functions. ceil(0) returned 1,

numeric_in accepts exponents; numeric to int4 rounds; float4/8 to numeric

is considerably more robust and accurate than it used to be.
Also, get rid of numeric's private allocation freelist, which is no longer
a win since Jan rewrote palloc.

Use sprintf() to convert float8 to a string during conversion to numeric.

Original code used float8out(), but the resulting exponential notation
was not handled (e.g. '3E9' was decoded as '3').
