[yocto] [opkg-utils][PATCH 00/22] Partially prepare for python3 and fix old Packages file reuse

[Martin Jansa]

First 5 patches are taken from oe-core.

Then there are some cleanups and fixes for issues I've found while looking 
for cause of very long package-index calls.

Some patches uses compatible changes from 2to3 (tested with python2.7), but
python3 support is not 100% complete, but were closer.

And in the end I've found the cause.. printing long fields (e. g. description)
with opkg.py was producing empty lines in Packages file (which are Packages entry 
separators) so only first entries till first empty line were processed from old
Packages file and the rest was always extracted from control files in packaged .ipk.

And this also fixes Packages.filelist generation.

I don't use python very much, so please review.

And the speedup? Almost 60 times :)
