Add *-dbg packages to build
Fix USER.CREATE's shadow entry creation

- sp_lastchg should be set (days since Jan 1 1970)
- sp_pwmin, sp_inact and sp_expire should be -1 (empty string)
- sp_flag should be ~0UL (also the empty string)
Fix missing -S option
Implement clockd -t/--test

It was in the man page, so it must be true, right?
Fix "Success" errno = 0 message under --test
Valgrind memcheck for Pendulum Usage

- New t/memcheck/*.t tests run various helper programs under Valgrind's
  memcheck tool and look for _any_ leakage whatsoever
- Numerous fixes to the Pendulum VM implementation to avoid leaks
Fix subtle memory leak in aug_find caller

Previously, we weren't freeing memory if we didn't get exactly one
result from our find, because of the bail-early-on-failure logic.
Merge branch 'cfm-60.shadow'
Fix pathing for VPATH builds
Fix memory leaks in policy code and tests

The tests mostly just weren't calling free() on the cw_hash_t that they
dynamically allocated; but it was throwing off t/memcheck/22-units.t,
which runs all unit tests (executable files in t)
Fix memory leaks in PDU handling

For the most part this was just missing calls to cw_pdu_destroy(pdu).
However, testing did uncover one particularly nasty leak with
cw_pdu_recv; NULL addressing frames were being silently leaked, because
they are ignored by pdu->src and not appended to the list of payload
frames (for good reason).  Solution was simple, and we now have tests to
guard against future such leaks.
Bail early in t/memcheck/22-units.t

Otherwise, `make test` in environments without valgrind fails.

Fix Memory Leaks in clockd and associated code
Fix Memory Leak in Pendulum Code

Successive calls to &USERDB.OPEN would leak the memory held by objects
from the previous open/parse.
