[Qemu-devel] [PATCH 11/17] Introduce OS specific cmdline argument handling and move SMB arg to os-posix.c

[Jes.Sorensen@redhat.com]

From: Jes Sorensen <Jes.Sorensen@redhat.com>

Introduce OS specific cmdline argument handling by calling
os_parse_cmd_args() at the end of switch() statement. Move option
enum to qemu-options.h and have it included from os-posix.c and
os-win32.c in addition to vl.c.

In addition move SMB argument to os-posix.c
