[CFARM] Script for automatic checking of patches


Here is a script that is automating the build and test of a gcc tree.
The interface uses a directory in which are scheduled patches to be
tested.  The tester goes to sleep for a minute if there is nothing in
that directory.  Otherwise it moves one of the patches to a testing
directory, updates the trunk, patches, and goes for a bootstrap and
test cycle.  In a patch to test, one can insert comments that are
processed by the checker: for example, here are the lines that I
included in one of my patches for bootstrap and test on gcc13:

configure: --disable-multilib
make: -j4

These keywords should be at the beginning of a new line, and can be
inserted anywhere in the patch file.

For the moment it is not possible to send emails from the compile
farm, but the functionality should work if a sendmail is set up.  My
intent is to allow other users of the cfarm to scp their patches to
this auto-tester patches directory.

I'm still quite annoyed by the fact that when new fails are inserted
in trunk, there is no way to filter out these new fails from the fails
due to the tested patch.  One possible solution is to schedule every
now and then a bootstrap of a pristine tree to reset the set of
passing tests, but this can be done outside the tester.

I also would like to include this script in gcc/contrib. Okay for trunk?
