Subject: [PATCH] Monkey-patch .decode() method to our strings as a temporary
compat crutch
As a temporary crutch to support faster deployment of the sane
string behavior on python3, monkey-patch a decode method into all
strings we return. This seems to be enough to fix practically all
API users who have already adapted to the long-standing broken API
on Python 3. API users compatible with both Python 2 and 3 never needed
this anyway. Issue a warning with pointer to the relevant bug when the
fake decode() method is used to alert users to the issue.
This is certainly an evil thing to do and will be removed as soon as
the critical users have been fixed to work with the new, corrected
behavior.

Subject: [PATCH] Add read-only support for sqlite
Based on latest upstream sqlite backend version, chainsaw write support
out and adjust for the infra differences (which there are more than a
few) and add an error message instead.

Add quoting to literal curly brackets
These curly brackets are already treated as literals by the shell, so
let's make that explicit for clarity, and silence a ShellCheck warning
at the same time.

Subject: [PATCH 2/7] Always free the arg list passed to rpmGlob()
Even though the actual implementation of rpmGlob() does not allocate the
passed arg list (av) if the return code (rc) is non-zero or arg count
(ac) is 0, it's the responsibility of the caller (rpmInstall() here) to
free that memory, so make sure we do that irrespectively of the above
conditions.

it part of the public API) so it's basically a no-op... Still, rather
