tests: add a test for symbol hiding side effects The worry here is that a binary linking with libnotmuch might lose access to Xapian::Error symbols because libnotmuch hides them. We are careful here to create ./fakedb/.notmuch in order to trigger a Xapian exception, and not just a missing file check. Thanks to jrollins and amddragon for suggestions. (cherry picked from commit 66f37f5f6864a988f94ddb893e3a176af57f6c8e)

# This test tests whether hiding Xapian::Error symbols in libnotmuch
# also hides them for other users of libxapian. This is motivated by
# the discussion in http://gcc.gnu.org/wiki/Visibility'

test: whitespace-cleanup for most test/* files Used emacs (whitespace-cleanup) function to "cleanup blank problems" in test files where that could be done without breaking tests; test/emacs was partially, and test/multipart was fully reverted.

test_begin_subtest 'comparing existing to exported symbols'
test: simplify T360-symbol-hiding, use nm instead of objdump After yet another variation in objdump output caused this test to fail (on a Debian port, no less), I decided whatever putative benefit we get from looking at the object files instead of the library isn't worth the maintenence headache. This version uses nm -P. nm -P should be portable, and fixed format. It purposely doesn't use the -D argument, since that is non-POSIX and nm on GNU/Linux seems do the right thing without it. It still won't work out of the box on e.g. Mac OS/X. I think the right thing to do there is to move some more configuration information into sh.config.
