With the eviction flushing stuff we'll want to allow for different
states, but still work basically the same way that
priority_reclaim_metadata_space works currently. Refactor this to take
the flushing states and size as an argument so we can use the same logic
for limit flushing and eviction flushing.

We're going to make this logic a little more complicated for evict, so
factor the ticket flushing/waiting code out of __reserve_metadata_bytes.
This has no functional change.

Currently we handle the cleanup of errored out tickets in both the
priority flush path and the normal flushing path. This is the same code
in both places, so just refactor so we don't duplicate the cleanup work.

Delayed iputs could very well free up enough space without needing to
commit the transaction, so make this step it's own step. This will
allow us to skip the step for evictions in a later patch.

This is prep work for moving all of the block group cache code into its
own file.

We don't need an if-else-if chain where we can use a simple OR since
both conditions are performing the same action. The short-circuit for OR
will ensure that if the first condition is true, can_overcommit() is not
called.

Now that we've moved all of the users to space-info.c, unexport it and
name it back to can_overcommit.

We'll need this exported so we can use it in all the various was we need
to use it. This is prep work to move reserve_metadata_bytes.

These are the basic init and lookup functions and some helper functions,
fairly straightforward before the bad stuff starts.
