[PATCH 0/6] bsd-user upstreaming: read, write and exit

[Warner Losh <imp@bsdimp.com>]

This series of patches continues the effort to get system calls working
upstream. This series was cleaved off a prior series to give me time to rework
based on the feedback from the first time I posted these.

These still need review based on comments from  Richard Henderson

       o bsd-user/freebsd/os-syscall.c: lock_iovec
I rewored to use g_try_new, as well as fixing bugs in the 'after a FAULT
handling code' Created a common routine to cleanup after errors that can
be used for the unlock_iovec.

       o bsd-user/freebsd/os-syscall.c: unlock_iovec
Fixed the error handling to be consistent with a normal unlock_iovec.

       o bsd-user/freebsd/os-syscall.c: Tracing and error boilerplate
Created the wrapper function as suggested in prior reviews.

The others were reviewed before, and haven't changed in any real way, but more
eyes likely won't hurt.
