bdb_get_hash_by_index returns a hash entry from a BDB using an index.
bdb_get_hash is also renamed to bdb_get_hash_by_type. bdb_get_hash
is deprecated. Callers are expected to call bdb_get_hash_by_index(buf, 0)
instead.

This patch adds code which dervies secrets from BDS. It's supposed to be
done by SP-RO, hence the code is mostly useful for testing (or emulation).
vba_extend_secrets_ro takes a function pointer to a hash extend
function. It'll be used to try different sha256 extend algorithms.

by AP-RW to update a BUC.

This patch converts TEST_* functions to macros, which print file name
and line # of the check. This will allow us to locate a failed test
quickly.
New TEST_* macros also automatically generate a test name if
testname == NULL. This will save us time to think of a name for
every single check we write in a test.

vba_bdb_init initializes the vboot context and decides what to do next
based on the vboot register content. Possible actions are:
1. proceed to verify the current slot
2. reset to try the other slot
3. reset to recovery mode
bdb_sprw_test demonstrates these actions.
