session: add infra for safe pool reallocs
This is not to be used lightly.
The idea is to forces pool reallocs to be done only on main thread with
a barrier to make sure pools are always reallocated without
peekers/readers. If rpcs are delayed and the pool runs out of elements,
workers will block waiting for barrier and force the realloc.
Consumers of this api should be session layer and transports.
