tdb2: test: convert (non-invasive) run tests to api tests.
This reduces compilation time, since these are merely linked with the
pre-built module, rather than recompiling it into the test (which
allows for fancy things like failtest).
This reduces the test compile time down from about 62 seconds to 45
seconds. Since ccanlint compiles tests three times (once normally,
once with coverage, and once with reduced config.h) this makes a
difference: we go from 780 seconds to 729 seconds.

tdb2: test: fix run-57-die-during-transaction.c to be more efficient.
We track malloc and free, but we didn't catch the free() inside
external_agent, which means that our list of allocations keeps
growing. Particularly under valgrind, which re-uses memory less than
the glibc allocator.

tdb2: don't continue if tdb1_find fails.
The TDB1 code's tdb1_find() returns 0 on error; the callers should
not assume that the error means that the entry wasn't found, but use
last_error to determine it.
This was found by looking at how long the failure path testing for
test/run-10-simple-store.c was taking under valgrind, ie:
valgrind -q ./run-10-simple-store --show-slowest
This change dropped the time for that test from 53 seconds to 19
seconds.

tdb2: test: try (almost) all tests with TDB_VERSION1 flag.
There are some minor changes required, in particular:
1) Make sure lockcheck understands tdb1 allrecord lock upgrades.
2) Handle tdb1 sequence number jumps: various operations increment the
sequence number twice, especually tdb_append.
3) Don't test fail on unlock, since it gets triggered with traversal on the
tdb1 backend (we didn't actually ever test this case for tdb2).
4) Move clear_if_first to offset 4, to match tdb1.

We're always allowed to unlock after a fork; by setting the count to 0

It's actually quite a good fit; we use compare_wrong_bucket for dead

tdb2: catch errors in tdb1_needs_recovery()
The tdb1 backend simply returns "true" if there's an error determining
if a tdb needs recovery. But this leads failtest down a rabbit hole;
it's better to return the error at this case (and makes for better for
diagnostics, since they will come from the first fault, not later in
tdb1_transaction_recover().
