...
print_package_info is already able to deal with stale data and we
better not deadlock other threads or processes there.

This is a complete rewrite of the PackageInstallAction class, due to
potentially state data collected on setup() that should be rather
collected with the lock held for the whole install transaction.

[entropy.client.package.actions] fetch: avoid potential deadlocks
...
Holding shared locks on other downloadable files while holding an
exclusive lock on the file to be downloaded is looking for a disaster.
Try not to hold locks on other potentially downloadable files while
holding one already.

[entropy.db.sqlite] drop support for locking based on rwsem for memory repositories
...
Firstly, rwsem is semantically different from flock (but this was known) and
this may confuse the API consumer. Secondly, the locking infrastructure is
purely meant for inter-process synchronization, threads synchronization is
not a current use case.
