Stop using a pool of threads for database operations

Now that squee cooperates with suspendable ports, this is unnecessary. Use a
connection pool to still support running queries in parallel using multiple
connections.

Partition the package_derivations_by_guix_revision_range table
...
And create a proper git_branches table in the process.
I'm hoping this will help with slow deletions from the
package_derivations_by_guix_revision_range table in the case where there are
lots of branches, since it'll separate the data for one branch from another.
These migrations will remove the existing data, so
rebuild-package-derivations-table will currently need manually running to
regenerate it.

I've see this error [1] which may relate to the derivation-output-details-id
not being a number, so this check should confirm if there is a issue.

Previously the package_derivations table wasn't considered, which would mean
derivations would still be referenced. This commit fixes that, along with also
deleting unreferenced entries in some linter related tables.

Some revisions have got disassociated from branches, probably because they
were associated with multiple branches in the first place. This should allow
deleting them.

Rework the shortlived PostgreSQL specific connection channel
...
In to a generic thing more like (ice-9 futures). Including copying some bits
from the (ice-9 threads) module and adapting them to work with this fibers
approach, rather than futures. The advantage being that using fibers channels
doesn't block the threads being used by fibers, whereas futures would.

then looking at each to see if it can be deleted, do some imperfect but not
too slow checks in the initial query.

of the information related to a revision.
