Previously, we cleaned the downloaded performance corpus and the
cached indexes on 'make clean'. This seems heavy-handed, since these
take a long time to download, unpack, and index. They also aren't
make targets to begin with. Move cleaning these to 'make distclean'.
This isn't exactly the right meaning of "distclean", but it's closer.

test: initial performance testing infrastructure
Fix the build breakage.
Out-of-tree 'make test' has been broken since earlier than the above,
and remains broken, as does out-of-tree perf test, but at least the
build now works.
The idea is run some code under valgrind --leak-check=full and report
a summary, leaving the user to peruse the log file if they want.
We go to some lengths to preserve the log files from accidental
overwriting; the full corpus takes about 3 hours to run under valgrind
on my machine.
The naming of the log directories may be slightly controversial; in
the unlikely event of two runs in less than a second, the log will be
overwritten. A previous version with mktemp+timestamp was dismissed as
overkill; just mktemp alone does not sort nicely.
One new test is included, to check notmuch new for memory leaks.
This is almost entirely renaming files, except for updating a few
references to those file names, and changing the makefile target.
A new set of memory tests will be run separately because they take
much longer.
This is not near as fancy as as the unit tests, on the theory that
the code should typically be crashing when performance tuning.
Nonetheless, there is plenty of room for improvement. Several more of
the pieces of the test infrastructure (e.g. the option parsing) could
be factored out into test/test-lib-common.sh
