Unroll Salsa20 fully for a little more speed (non-SSE now almost as fast as SSE)

Little bit of reorg in Salsa20 which seems to speed things up very slightly.

Add build def ZT_NO_TYPE_PUNNING, which when defined disables type punning code that might cause unaligned access errors on architectures that care (e.g. Android/ARM)

Revert slow non-SSE Salsa20 modification since it did not fix Android/ARM issue. Also update Salsa20 comments and clean up a bit.

For @glimberg -- a *possible* fix to the alignment headaches on Android/ARM. If this works we should find a define that can be used to enable it there since it will slow things down on non-x86 other architectures.

Get rid of __align stuff in Salsa20 -- not portable, does not seem to help much on newer chips.

Salsa20 SSE Windows build fix -- turns out you can't be as loose with SSE intrinsics in Visual Studio

Make Salsa20 variable-round, allowing for Salsa20/12 to be used for Packet encrypt and decrypt. Profiling analysis found that Salsa20 encrypt was accounting for a nontrivial percentage of CPU time, so it makes sense to cut this load fundamentally. There are no published attacks against Salsa20/12, and DJB believes 20 rounds to be overkill. This should be more than enough for our needs. Obviously incorporating ASM Salsa20 is among the next steps for performance.
