lib: Add threadpool manager

This adds a threadpool manager component in the library that is used
in the IRMd and IPCPs. The threadpool manager now doesn't detach
threads but does a join when they exit. This solves a data race in the
previous implementation where some threads were not completely finished
upon release of some resources.
