Alexander Neumann 24b14e21cc Remove pools for nodes and IDs 
This removes the allocation pools for nodes and IDs. I feel they aren't
really needed. Benchmarks:

The variable DEBUG_BREAK can be used to set a breakpoint (implemented
using SIGSTOP):

    DEBUG_BREAK=Archiver.Snapshot ./restic backup foo
