add osmo_use_count API
Provide a common implementation of use counting that supports naming each user
as well as counting more than just one use per user, depending on the rules the
caller implies.
In osmo-msc, we were originally using a simple int counter to see whether a
connection is still in use or should be discarded. For clarity, we later added
names to each user in the form of a bitmask of flags, to figure out exactly
which users are still active: for logging and to debug double get / double put
bugs. This however is still not adequate, since there may be more than one CM
Service Request pending. Also, it is a specialized implementation that is not
re-usable.
With this generalized implementation, we can:
- fix the problem of inadequate counting of multiple concurrent CM Service
Requests (more than one use count per user category),
- directly use arbitrary names for uses like __func__ or "foo" (no need to
define enums and value_string[]s),
- re-use the same code for e.g. vlr_subscr and get fairly detailed VLR
susbscriber usage logging for free.
