Subject: [CRYPTO] salsa20_i586: Salsa20 stream cipher algorithm (i586 version)

This patch contains the salsa20-i586 implementation. The original
assembly code came from
<http://cr.yp.to/snuffle/salsa20/x86-pm/salsa20.s>. I have reformatted
it (added indents) so that it matches the other algorithms in
arch/x86/crypto.
