Subject: [PATCH v4] QEMU samba daemon: additional command line options

The smbd daemon takes additional command line options
from environment variable SMBDOPTIONS.
Set the environment variable SMBDOPTIONS before executing qemu.

Example:

export SMBDOPTIONS="--option='server min protocol=CORE' -d 4"
