V4L2 kernel drivers allow configuration of the hardware settings via a
mechanism called controls. These can be referred to by name such as
"Brightness" and "White Balance Temperature". The user-space command line
client for setting these controls (v4l2-ctl) normalises these names such
that they only contain lower case alphanumeric characters and the
underscore '_'. e.g:
Kernel v4l2-ctl
----------------------------------------------------
Brightness brightness
White Balance Temperature white_balance_temperature
Focus (absolute) focus_absolute
GStreamer seems to want to follow this pattern but failed for controls with
more than one consecutive non-alphanum character. e.g. GStreamer would
produce "focus__absolute_" rather than "focus_absolute".
This commit fixes that issue. Backwards compatibility is preserved by
normalising all control names before comparison.
