overhaul of the thread support. Many things are now probably broken,
but at least with --tool=none, simple and not-so-simple threaded and
non-thread programs work.

table/cache management. Two main changes. (1) Translation areas are
recorded using VexGuestExtents, so that Vex is now properly supported
and code deletion works correctly. (2) Low overhead BB profiling,
enabled by the --profile-flags=<XXXXXXXX> option. This finds the top
N bbs at exit and shows them, so as to give a basis from which to do
performane tuning.
To support this, the way tt/tc work is changed. It is still a
sectored arrangement, but now each sector has its own hash table.
This simplifies a lot of things.

--logfile-fd --> --log-fd
--logfile --> --log-file
--logsocket --> --log-socket
to be consistent with each other and other options (esp. --input-fd). Also
renamed some related variables. The old names still work, for backwards
compatibility, but they're not documented.

- If no tool is specified, V now gives a short message and a list of
available tools. This was meant to happen previously, but a bug prevented
it from working properly; it gave the usage message instead.
- If a bad option is given, V now gives a short message rather than the full
--help. This make V consistent with all other programs I looked at.
- Now returning 0 when you do 'valgrind --help' and 'valgrind --version'
as other programs do.
- Removed VG_(startup_logging)() and VG_(shutdown_logging)() as they were
empty and have been for a long time (always?).
- Added various tests for these scenarios. Had to change the regtest
script slightly to allow for malformed command lines.
This addresses bug (wishlist) #82999.
