[PATCH] Remove two initialization functions

[Tom Tromey <tom@tromey.com>]

I noticed a couple of initialization functions that aren't really
needed, and that currently require explicit calls in gdb_init.  This
patch removes these functions, simplifying gdb a little.

Regression tested on x86-64 Fedora 34.
