[PATCH v2 0/3] Use ui-out tables in a few spots

[Tom Tromey <tom@tromey.com>]

This series changes a few spots to use ui-out tables rather than
hand-aligned printf-based ones.  I think ui-out tables should
generally be preferred:

* They are more flexible and easier to use

* They sometimes provide automatic styling (like addresses in this
  series)

* They allow the possibility of structured reuse via MI

There are still a few such tables left in gdb after this series, but
they are all in code I can't readily test: fbsd-tdep.c,
darwin-nat-info.c, and netbsd-tdep.c.

Regression tested on x86-64 Fedora 38.
