libmemif: introduce 'memif_per_thread_' namespace
APIs in 'memif_per_thread_' namespace are used to split the global
database into separate databases, to improve multi-thread use cases.
Using 'memif_per_thread_init' client can create separate libmemif
databases (libmemif_main_t). Client will reference these databases
using memif_per_thread_handle_t. Each database requires unique socket.
Created interface will be stored in the same database as the socket
passed in connection arguments.
Example code: extras/libmemif/examples/icmp_responder_3-1/main.c
Type: feature
