184bc45f68 Unified - adapt the generation of aes assembler to use GENERATE 
This gets rid of the BEGINRAW..ENDRAW sections in crypto/aes/build.info.

This also moves the assembler generating perl scripts to take the
output file name as last command line argument, where necessary.

053fa39af6 Conversion to UTF-8 where needed 
This leaves behind files with names ending with '.iso-8859-1'.  These
should be safe to remove.  If something went wrong when re-encoding,
there will be some files with names ending with '.utf8' left behind.

256 byte S-box. AES_cbc_encrypt needs further work as it should also use
slow routines when processing smaller amount of data.

af8c1d81a3 Reimplement outer rounds as "compact" in x86 assembler. This has rather 
strong impact on decrypt performance, 20-25%. One probably should consider
switching between slower and faster routines depending on how much data
we were asked to process.

9598fa8759 Mitigate the hazard of cache-collision timing attack on last round. Well, 
prefetch could have been moved closer to Td4 references. Something for
later consideration...

c8d5c71af5 Mitigate cache-timing attack in CBC mode. This is done by implementing 
compressed tables (2x compression factor) and by pre-fetching them into
processor cache prior every CBC en-/decryption pass. One can argue why
just CBC? Well, it's commonly used mode in real-life applications and
API allows us to amortize the prefetch costs for larger data chunks...
