All test scripts to be executed are now named as T\d\d\d-name.sh,
numers in increments of 10.
This eases adding new tests and developers to see which are test scripts
that are executed by test suite and in which order.
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.
Tester may have set LD_LIBRARY_PATH to find libraries required
by notmuch. Therefore add $TEST_DIRECTORY/../lib to the beginning
of current list of library paths in $LD_LIBRARY_PATH before running
symbol-test.
If symbol-test is built in symbol-hiding with hardcoded g++ invokation,
it's not so easy to pass $(srcdir) which is required to find notmuch.h
when srcdir and builddir are separate directories.
Change add_email_corpus, emacs_deliver_message and tests to use
$TEST_DIRECTORY instead of '..'.
This improves the behavior of the usage of --root=<dir>, as the
assumption of what '..' means will usually be incorrect.
Document -root option in README and update valgrind to work with
-root.
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.
