Map instance
Given an existing file descriptor pointing to an eBPF map, obtain its information and return a MapRef instance pointing to that map (but creating a duplicate descriptor).
Note: If parameters is passed, it will be used as
a fallback to build the MapRef for kernels older than 4.13.
Make sure it's correct. If not passed, the call will fail
for older kernels.
If transfer is true, the passed FD itself is used
(taking ownership of it) instead of creating a new FD first.
Do this only if the FD isn't being used anywhere else.
If the file descriptor is invalid, the function throws without taking ownership. Note that there is no way to check whether the FD actually points to an eBPF map, the caller is responsible to check first.
