[v3] minor cleanups

[Phil Edwards]

These three minor changes don't affect exiting code, but were tested on
x86/linux nonetheless, with no regressions.

With the configury creating a testsuite/Makefile, we no longer need
to check for the existence of a testsuite directory when using mkcheck.
The __sink_unused_warning<> code hasn't been used on the trunk for a long,
long time; Benjamin said it could be removed way back when, but I never got
'round to it.  And with the testsuite_hooks.h.in file being renamed and
moved so that it's no longer generated, we don't need testsuite_flags'
INCLUDES to search the build directory anymore.

All three have been applied to the trunk.  The Makefile.am change has also
been applied to the branch with a suitably modified log entry.  (The other
two changes do not apply to the branch.)  Also, I took the opportunity to
clean up some formatting errors in the trunk&branch ChangeLogs themselves
(mostly leading spaces and other twiddly no-nos).
