new generic in aes.vhd: ovl_enable (boolean); copy of aes_pkg.vhd to
integrate ovl functions; copy of tb_aes.vhd to integrate ovl function

move all rtl *.vhd files into the new vhdl directory in the rtl
directory

- OVL now in own library 'accellera_ovl_vhdl
- OVL now default setting
- definition of control OVL configuration record 'ovl_proj_controls' in
package file 'aes_pkg.vhd'

- new variable OVL_ENABLE to enable OVL compile
- new variables OVL_LOC & OVL_SRC which point to the OVL library files
- new GHDL analyze of the OVL library

Initial release of TDES according to FIPS 46-3 specification

Initial release of TDES according to FIPS 46-3 specification

corrected some bugs which were found while testing cbc ability

integrated all decryption tests of NIST 800-17 publication except the
modes-tests

integrated all encryption tests of NIST 800-17 publication except the
modes-tests

cbcdes.vhd and tb_cbcdes.vhd are still incomplete, maybe they contain
some bugs

now with all ecb tests of NIST 800-16 publication except the modes-tests

integrated more tests of NIST 800-16 publication
