2049a3c874 TLS: Use os_memcmp_const() for hash/password comparisons
This makes the implementation less likely to provide useful timing
information to potential attackers from comparisons of information
received from a remote device and private material known only by the
authorized devices.

54ac6ff8c4 PKCS 1: Add function for checking v1.5 RSA signature
This could be used as a step towards replacing more specific functions
used in X.509 and TLS processing.

6c5be116dd PKCS #1: Enforce minimum padding for decryption in internal TLS
Follow the PKCS #1 v1.5, 8.1 constraint of at least eight octets long PS
for the case where the internal TLS implementation decrypts PKCS #1
formatted data. Similar limit was already in place for signature
validation, but not for this decryption routine.

e6d83cc7ba PKCS #1: Allow only BT=01 for signature in internal TLS
Based on PKCS #1, v1.5, 10.1.3, the block type shall be 01 for a
signature. This avoids a potential attack vector for internal TLS/X.509
implementation.

f1739bac4f Move PKCS# {1,5,8} functionality into separate files
This functionality fits better with src/tls (i.e., internal TLS
implementation), so move it there to make crypto_internal.c more
of a wrapper like other crypto_*.c files.
