Anything that moves hundreds of lines out of vl.c can't be all bad.

error_report() terminates the message with a newline. Strip it it
from its arguments.
This fixes a few error messages lacking a newline:
net_handle_fd_param()'s "No file descriptor named %s found", and
tap_open()'s "vnet_hdr=1 requested, but no kernel support for
IFF_VNET_HDR available" (all three versions).
There's one place that passes arguments without newlines
intentionally: load_vmstate(). Fix it up.
Add READ_16 + friends to scsi-defs.h, scsi_command_name() and the
request parsing helper functions.
Use them in scsi-disk.c too.
