[PATCH v5 0/2] Make sure autoload happens before notifying Python side in new_objfile event

[Simon Marchi]

This is a new version of Michael Weghorn's patchset here:

https://sourceware.org/pipermail/gdb-patches/2021-April/178069.html

I rebased it after merging my "set debug observer" changes.

In addition to just rebasing, I made many style fixes here and there.  I
also did some changes in the test to use some more recent GDB testsuite
idioms (that you would miss if you copied an older test, and that I
wouldn't expect a new-ish contributor to know).

I also changed the test to make it work for the native-gdbserver board.
Previously, the test checked the output of the "run" command.  This
doesn't work for native-gdbserver, because GDB is connected using the
"remote" protocol, which doesn't support running.  Instead, I made the
new_objfile handler set a global variable if everything looks good.  We
then check the global variable value in the test.

Michael, can you please take a look and check it is still ok with you?
