FreeBSD has a MI ucontext structure that contains the MD mcontext machine state and other things that are machine independent. Create an include file for all the ucontext stuff. It needs to be included in the arch specific files after target_mcontext is defined. This is largely copied from sys/_ucontext.h with the comments about layout removed because we don't support ancient FreeBSD binaries.
