[PATCH v2 0/6] bsd-user upstreaming: read, write and exit

[Warner Losh]

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.

       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.

V2: Use g_try_new0 and simplify based on not needing to initialize things
to zero that are already zero. Only affects the 'lock_iovec' hunk.

V2: Remove inline tags from do_bsd_* routines.

V2: Clean up logging a little

Now all the patches, except the last one, need to be reviewed.
