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.

If key digest matching is not required (i.e. verify-bdb-key efuse
flag is not set), bdb_verify skips digest matching. This change makes
bdb_verify accept null pointer for the key digest parameter.

Defining these symbols weakly causes the output executable to hit
segmentation fault because ld chooses *UND* symbols over the definition
when they appear in *.a archive:
$ objdump -t build/libvboot_utilbdb.a
bdb.o:
0000000000000000 w *UND* 0000000000000000 bdb_rsa4096_verify
...
rsa.o
000000000000061f w F .text 0000000000000111 bdb_rsa4096_verify
...
This happens regardless whether the symbol is referenced or not;
or whether the object defining the symbol appears earlier than the
reference or not.

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.
