Remove AES

[codereport]

I am pretty sure the following files:

/jsrc/aes-arm.c
/jsrc/aes-arm_table.h
/jsrc/aes-c.c
/jsrc/aes-c.h
/jsrc/aes-ni.c
/jsrc/xaes.c

can be removed with a little bit of work. From what I can tell, it is support for Advanced Encryption Standard which doesn't seem essential.
