Subject: [PATCH 01/10] Use most recent Ubuntu when running tests

The combination of gcc 9.4 and gdb 9.2 in Ubuntu 20.04 have a few
minor test issues that seem to be bugs in gdb that have been since
fixed.

Subject: [PATCH 02/10] Make first line of C method consistent

The tests were relying on specific number of executable lines
in a function. However on some gdb/gcc combinations stopping
at a function stops at the line with the `{` and some
on the first line witin that function. Much of the tests
here assumed that latter. By using line tags we don't need
to worry about exact number of executable lines between entry
and area of interest. And by placing first line of code on
the same line as the opening `{` of the function, we can
have consistent stop locations when stepping into a function.

Subject: [PATCH 03/10] Fix undefined behaviour in C code problem

Without the return, this code would core dump, depending
on compiler version. The compiler was generating a warning
too about the missing return.

Subject: [PATCH 04/10] Update tests for GDB >= 12 for change in formatted
 values

From GDB news:

print
  Printing of floating-point values with base-modifying formats like
  /x has been changed to display the underlying bytes of the value in
  the desired base.  This was GDB's documented behavior, but was never
  implemented correctly.

This commit updates the tests to accomodate GDB's change.

Fixes #210

Subject: [PATCH 05/10] Run the loop fewer times

This test sometimes hangs when run a lot. As best as I can tell this
is a Ubuntu problem, rather than a gdb problem as it only fails on
Ubuntu 24.04, but I am not sure. I cannot reproduce the problem
when using the UI.

"script" field of a breakpoint used to be output as a tuple (<= GDB 12),
though it is a list. There are cases of flags that can be applied to
get old or new behaviour too.
This code handles both cases transparently.

Subject: [PATCH 07/10] Explicitly start gdb with mi2

We should explicitly set the version of mi to use. Until recently
mi == mi2, but with the recent introduction of mi3 as the default
we need to be explicit.

The other place that specifies interpreter is explicit about version
and includes an important comment on the subject

Subject: [PATCH 09/10] Allow a little more time for tests to run

The DSF-GDB tests themselves can take an hour or so.

Subject: [PATCH 10/10] Try automatically re-running failed tests

This will try to rerun failed tests up to three times.
The side effect is that a very broken test run will take much
longer to complete, but it is hoped for those few
https://github.com/eclipse-cdt/cdt/labels/flakytests in the system
this will resolve the issue.

Note this is applied only to the GitHub actions run, not to Jenkins
run where we build releases from. Ideally we don't want to do that
there.

In a future commit we can consider removing flakyTest from -DexcludedGroups
too.

See [surefire docs](https://maven.apache.org/surefire/maven-surefire-plugin/examples/rerun-failing-tests.html)
for details.
