stat("C:") seems to fail.

Old filesystem handler was global and did not have any application-specific callback handle.

Only complete blocks can be decrypted. Block is always exactly 32 packets.
Reset encryption indicator in header while checking sync bytes.

In _mmc_read_auth() MMC commands are used to retrieve MKB from the
drive to display a warning if a host certificate is
revoked. Unfortunately, reading MKB using MMC is very slow (up to 10
seconds) and it bypasses OS cache so it takes the same amount of time
every time. _mmc_read_auth() is called several times (VID retrieval,
PMSN retrieval, read data key retrieval), which can cause up to 30
second delay when trying to play a disc (VID is cached, but PMSN is
not and BD-J code tends to try to retrieve it even when there is no
PMSN on the disc).

Fix this by removing MKB retrieval in _mmc_read_auth(). This only
causes a warning not to be displayed, however there still will be an
information if the host certificate is revoked (drive will simply
reject it).

There seems to be a slight change in S-expressions (fortunately
backward compatible). There is also additional flag needed in rather
strange place (data section instead of key section), most probably a
bug in gcrypt.

Decrypting a 350MB file with gcrypt 1.5 takes around 4 seconds on Core
Quad Q9450 2.66GHz while with gcrypt 1.6 around 2.8s (the processor
does not support AES-NI).

f888ebf5 caused first title entry from KEYDB.cfg to be ignored as it is
trying to add entries to uninitialized list, and just prints following
warning:
Error: No title list passed as parameter.
Fix it by moving initialization to proper place.
