Xavier Roche bfc4a016ab Replace single-letter -# self-tests with a named -#test=NAME registry (#427)
The hidden engine self-tests had accreted into a grab-bag of arbitrary
single-letter/-digit -# arms (-#0, -#A, -#W, ...) buried in the htscoremain.c
option switch, with no mnemonics and stale --help text. Collapse them into one
registry: -#test lists every test with a usage hint and one-line description,
and -#test=NAME [args] runs one.

The handlers and the two helpers they used (basic_selftests,
string_safety_selftests) move to a new htsselftest.c keyed by a
{name, args, desc, fn} table; htscoremain.c keeps only a small dispatch that
runs ahead of the no-URL usage gate, so a bare -#test (or an arg-less test like
copyopt/dns/cookies) no longer needs a dummy URL token to be reached. The
genuine debug knobs (-#L, -#C, -#R, -#h, ...) stay as letters in the switch;
only the unit self-tests, whose sole callers are tests/01_engine-*.test, are
renamed, so this is internal-only with no compatibility surface. Behavior is
preserved: each test prints the same result line and exit code, which the
existing assertions pin. Three now-unused includes (htscache_selftest.h,
htsdns_selftest.h, htsencoding.h) drop out of htscoremain.c.

Tests: the engine tests move to -#test=NAME; 01_engine-hashtable now asserts its
success line (not just exit code) so a misrouted registry row can't pass, and a
new 01_engine-selftest-dispatch covers the bare-list and unknown-name paths.

The --help/man "guru options" list now points at -#test instead of enumerating
a stale subset. The lone vestigial alias --debug-testfilters still resolves to
the removed -#0 (it was already non-functional: param1 supplies one argument,
-#0 required two); it is left untouched because editing that array forces
clang-format to reflow the whole untouched table.
