Enable -Wcompat=error in the testsuite
Enabling -Werror=compat in the testsuite allows us to easily see the impact that a new warning has on code. It also means that in the period between adding the warning and making the actual breaking change, all new test cases that are being added to the testsuite will be forwards-compatible. This is good because it will make the actual breaking change contain less irrelevant testsuite updates. Things that -Wcompat warns about are things that are going to break in the future, so we can be proactive and keep our testsuite forwards-compatible. This patch consists of two main changes: * Add `TEST_HC_OPTS += -Werror=compat` to the testsuite configuration. * Fix all broken test cases.
