[PATCH v2 23/48] bsd-user: introduce host_os.h for bsd-specific code and defaults

[imp]

From: Warner Losh <imp@bsdimp.com>

Introduce host_os.h for frebsd, netbsd and openbsd. This sets the default bsd
being implemented today. In the future it will have code that is per-BSD
specific. Abstracted from a larger c93465b6208c4c95cc0a394ffef4180ba6ccf27a in
the qemu-bsd-user repo.
