wangjianyu3 f95b53d15b examples/camera: add -m option for horizontal mirror preview 
Add -m command line option to enable horizontal mirror on the
camera sensor via VIDIOC_S_CTRL + V4L2_CID_HFLIP.  This uses
the sensor hardware mirror (e.g. GC0308 register 0x14 bit[0])
with zero CPU overhead.

Also refactor parse_arguments to use a loop-based parser so
options can appear in any order.

Usage: camera 0 -m    (mirror preview)
       camera -jpg -m (mirror still capture)
