Log Message:
Obliterate the global var herefd

For the past several years (since Nov 2021) the global var "herefd"
has led a rather meaningless existence.

It gets statically init'd to -1 (at compile time), and several
times its value is carefully saved, set to -1, then restored later.
(Lots of copying around of -1 going on there!)

The only use of its value was removed in the immediately previous update
to memalloc.c, where it was tested, and if its value were >= 0 ...
(no point mentioning what would happen, since its value is always -1,
since Nov 2021).

Bye bye herefd, it was nice knowing you.   May we never meet again.
