affb3d70cb improve fortuna_import() 
This makes fortuna_import() kinda compliant to the "Update seed file"
behavior of the original paper.
It differs from the original behavior in that it allows to import
seed files which are larger	than 64 bytes.

144839a8db ltc: ctr: update pt and ct after acceleration 
Problem occurs in the condition of the following case:

1st decryption:
Decrypt a ciphertext whose length is a multiple of the block size (16B)
(len = n * block_size)
2nd decryption:
Decrypt the continuing ciphertext whose length is not a multiple of the
block size
(len = m * block_size + l)

In this case accel_ctr_encrypt() is firstly used at the 2nd decryption.
If pt and ct are not updated, the top (l = len % block_size) bytes of
decryption result are sometimes destroyed.

f9e90f5b1c revert the change of MAXBLOCKSIZE 
Currently this only plays a role in HMAC which still uses dynamic
allocation depending on the real blocksize defined by the hash
algorithm.

6da2211ee9 Update rsa_import.c 
Bug-fix: MAX_RSA_SIZE is the maximum RSA key size in *bits* (as commented in tomcrypt_custom.h), so the proper conversion to bytes (as the argument value to XCALLOC) would be to divide by 8 (bits per byte), not multiply by 8. This excessive allocation (32 Kbytes instead of 512 bytes) is readily apparent in memory-constrained environments.
