mdoc: remove superfluous paragraph macros.
Provide APIs to directly get 'lowmem' and 'highmem' size directly.

Previously the sizes were inferred indirectly based on the size of the mappings
at 0 and 4GB respectively. This works fine as long as size of the allocation is
identical to the size of the mapping in the guest's address space. However, if
the mapping is disjoint then this assumption falls apart (e.g., due to the
legacy BIOS hole between 640KB and 1MB).
Fix ifname normalization.  ifconfig_IF_alias{es,N} did not work if ifname has
any of [.-/+].

Put the aesni_cipher_setup() and aesni_cipher_process() functions into
the file which is compiled with SSE disabled.  The functions set up
the FPU context for kernel, and compiler optimizations which could
lead to use of XMM registers before the fpu_kern_enter(9) is called or
after fpu_kern_leave(9), panic the machine.

Catch up with many years of changes:

o Document PF_LOCAL as being an alias for PF_UNIX
o Document POSIX standardization of this interface using AF_*
  constants rather than PF_* constants, and note the three particular
  families which POSIX standardizes.
o Note anticipated POSIX standardization of SOCK_CLOEXEC.
o Delete from listing protocol families that FreeBSD doesn't support
  (in some cases, like PF_PUP, has never supported).
o Add to listing some current protocol families that have been
  introduced in the last decade or so.
o Document the correspondence of PF_* and AF_* constants.

We should probably change the documentation to make the AF_* constants
primary, but this commit does not do so.
