2.11: Add basic support for abi rules to the tools
Add basic "understand and keep" support for abi rules, where
"understand" means to not error out when seeing an abi rule, and "keep"
simply means to keep the original abi rule when serializing a profile.
On the long term, abi rules should be parsed (similar to include rules),
but for now, this patch is the smallest possible changeset and easy to
backport.
Note that the only added test is via cleanprof_test.* which is used by
minitools_test.py - and does not run if you do a 'make check'.
Oh, and of course the simple_tests/abi/ files also get parsed by
test-parser-simple-tests.py.
BTW: Even serialize_profile_from_old_profile() can handle abi rules ;-)
This is a backport of 072d3e04 / !202 (merged) to
2.11 (with some adjustments because that commit didn't appy cleanly)
I propose this patch for 2.10 and 2.11.
