[bitbake-devel] [PATCH] persist_data: Return str instead of unicode for sqlite3 text queries

Python 2's sqlite3 module defaults to returning Unicode strings for SQL
text queries, which could trickle down to other parts of bitbake code and
cause unexpected Unicode conversions. Using byte strings avoids this issue.
For example, the git fetcher's AUTOREV support caches HEAD SHA1's using
bb.persist_data, so sometimes the git command strings passed to fetch2's
runfetchcmd() were unicode, potentially causing UnicodeDecodeErrors when
it appended the values of environment variables containing non-ASCII chars.
