We have a strict separation between enum TpmType and be_drivers[]:
* TpmType may have any number of members. It just happens to have one.
* tpm_register_driver() uses the first empty slot in be_drivers[].
If you register more than tpm_models[] has space,
tpm_register_driver() fails. Its caller silently ignores the
failure.
If you register more than one with a given TpmType,
tpm_display_backend_drivers() will shows all of them, but
tpm_driver_find_by_type() and tpm_get_backend_driver() will find
only the one one that registered first.
Since we only ever register one driver, and be_drivers[] has space for
just that one, this contraption even works.
Turn be_drivers[] into a straight map from enum TpmType to driver.
Much simpler, and has a decent chance to actually work should we ever
acquire additional drivers.
While there, use qapi_enum_parse() in tpm_get_backend_driver().

Section "1.18 Miscellanea" is still too big: it documents 134 symbols.
Section "1.7.1 Block core (VM unrelated)" is also rather big: 128
symbols. All the others are of reasonable size.

A command is a query if it has no side effect and yields a result.
Such commands are typically named query-FOO, but there are exceptions.
The basic idea is to find candidates with query-qmp-schema, filter out
the ones that aren't queries with an explicit blacklist, and test the
remaining ones against a QEMU with no special arguments.
The current blacklist is just add-fd.
The test can't do queries with arguments, because it knows nothing
about the arguments. No coverage for query-cpu-model-baseline,
query-cpu-model-comparison, query-cpu-model-expansion, query-rocker,
query-rocker-ports, query-rocker-of-dpa-flows, and
query-rocker-of-dpa-groups.
Most tested commands are expected to succeed. The test does not check
the return value then.
query-balloon and query-vm-generation-id are expected to fail because
they need a virtio-balloon / vmgenid device to succeed, and this test
is too dumb to set one up. Could be addressed later.
query-acpi-ospm-status and query-hotpluggable-cpus are expected to
fail because they require features provided only by special machine
types, and this test is too dumb to set that up. Could also be
addressed later.
Several commands may either be functional or stubs that always fail,
depending on build configuration. Ideally, the stubs shouldn't be in
query-qmp-schema, but that requires QAPI schema compile-time
configuration, which we don't have, yet. Until we do, we need to
figure out whether a command is a stub. When we have a suitable
CONFIG_FOO preprocessor symbol is available, use that. Else,
simply blacklist the command for now.
We get basic test coverage for the following commands, except as
noted:
qom-list-types
query-acpi-ospm-status (expected to fail)
query-balloon (expected to fail)
query-block
query-block-jobs
query-blockstats
