Re: pre extending hash? - need speed

Restore the 5.003 gv_fullname() and gv_efullname() functions.
Provide new 3-arg forms gv_fullname3() and gv_efullname3().

The patch below (which is relative to perl5.001l) implements
"keys %hash = 50_000;" (or other integer-evaluable sizes) for
pre-sizing hashes.  I've only moved the patch forward from
when I first did it.  I'm sure the code in hv_ksplit could be
improved.
