  I wrote this patch series to fix PR cli/30934.

The 1st patch is an unrelated optimization, which I added to this series
because it touches the same code.

The 2nd patch factors out a function.

The 3rd patch adds a means to keep track of styling failures in the
source cache, as suggested here (
https://sourceware.org/pipermail/gdb-patches/2023-October/203164.html ).

The 4th patch fixes the PR cli/30934.

This is v2.  Changes since v1:
- fixed a build problem with --disable-source-highlight, reported by the linaro
  CI.
- temporarily installs the default_quit_handler to be able to use QUIT
- added a question whether to interrupt highlighting or not
  (in the RFC, I had a warning, in v1 I dropped it)
- added "gdb_assert (target_terminal::is_ours ())"

Adding the question was inspired by the v3 patch "gdb/debuginfod: Ctrl-C ask
to cancel further downloads" (
https://sourceware.org/pipermail/gdb-patches/2023-March/197679.html ).
