patch.bbclass: Merge patch enhancements from OE by Chris Larson

Chris made some interesting changes to the patch handling in OE. Firstly the
patch and pnum parameters have been renamed, to better reflect their function,
to apply and striplevel. The apply parameter now takes either yes or no as its
value.

Therefore a patch line would be changed from:
file://some.patch;patch=1;pnum=2
to:
file://some.patch;apply=yes;striplevel=2

Secondly the apply parameter is inferred if not defined. Entries in SRC_URI
with diff or patch filename extensions will be automatically applied as patches
if the apply parameter is not set to no (or an unknown value).

Note: We have disabled the warnings when using the old style parameters for now
