Add 'all' option to vidcap --list-formats(-ext) option to use
V4L2_FMTDESC_FLAG_ENUM_ALL if supported by the driver.
Update functions prototype to provide an additional parameter.
Signed-off-by: Benjamin Gaignard <benjamin.gaignard@xxxxxxxxxxxxx>

changes in version 3:
- Add 'all' suboption to --list-formats(-ext) options
