Introduce metadata style
This introduces a new "metadata" style and changes many places in gdb
to use it. The idea here is to let the user distinguish gdb output
from output that (conceptually at least) comes directly from the
inferior. The newly-styled category includes text that gdb
traditionally surrounds in "<...>", like "<unavailable>".
I only added a single test for this. In many cases this output is
difficult to test. Also, while developing this errors in the
implementation of the new printf formats showed up as regressions.
