Solver algorithms:
------------------
- the solver allows arch changes from/to noarch without complaining.
good or bad?
- vendow changes are allowed from unknown to known. libzypp doesn't
allow that. Feature?
- should prune_best_version_arch consider the arch or the vendor this
is about an installed package?
- repo priorities should influence the order in which package rules
are fulfilled.
- prune_best_version_arch has a n^2 loop when looking at obsoletes.
Should we create an obsoletes index to speed that up?
Code cleanup:
-------------
- move whatprovides/whatprovidesdata from pool to solver?
good: can implement installed(), though I don't know if we need
it.
bad: need to allocate solver if we just want to look up a provides.
can't re-use whatprovides for multiple solver runs with different
solvers.
- implement unified idarray in pool, so that repos don't have to
come with their own idarrays? Would need memory for hash, but
unification would be a nice thing. Would also fix solver memory
leak with learned rules. Needs some hard numbers abour memory usage.
- make bitmap macros inline functions?
- rename ID Macros to ID_, e.g. ARCH_NOARCH to ID_ARCH_NOARCH?
- support different streams than FILE in repo_ functions? Is it
enough that glibc supports FILE overloading, see the undocumented
fopencookie()?
