ffmpeg | branch: master | Zhong Li <zhong.li at intel.com> | Wed May 23 18:01:32 2018 +0800| [35ed7f93dbc72d733e454ae464b1324f38af62a0] | committer: Luca Barbato

qsvenc: Add an option to disable MFE mode

Provide proper aliases to enable/disable MFE.

The numeric values are ambiguous and misleading (e.g: user may misunderstand
setting mfmode to 1 is to enable MFE but actually it is to disable MFE, and
set it to be 5 or above is meaningless).

MFX_MF_MANUAL hasn't been exposed since it is to be implemented.
