linux(4): Get rid of Linuxulator kernel build options.

Stop confusing people, retire COMPAT_LINUX and COMPAT_LINUX32 kernel
build options. Since we have 32 and 64 bit Linux emulators, we can't build both
emulators together into the kernel. I don't think it matters, Linux emulation
depends on loadable modules (via rc).

Cut LINPROCFS and LINSYSFS for consistency.

x86: consolidate hw watchpoint logic into new file

This is a prerequisite to using these functions outside of ddb, but also
provides some cleanup and minor refactoring. This code is almost
entirely duplicated between the two implementations, the only
significant difference being the lack of dbreg synchronization on i386.

Cleanups are:
- demote some internal functions to static
- use the constant NDBREGS instead of a '4' literal
- remove K&R definitions
- some added comments

Add a kernel crypto driver using assembly routines from OpenSSL.

Currently, this supports SHA1 and SHA2-{224,256,384,512} both as plain
hashes and in HMAC mode on both amd64 and i386. It uses the SHA
intrinsics when present similar to aesni(4), but uses SSE/AVX
instructions when they are not.

Note that some files from OpenSSL that normally wrap the assembly
routines have been adapted to export methods usable by 'struct
auth_xform' as is used by existing software crypto routines.
