[R-sig-hpc] increasing max number of socket connections

[Ei-ji Nakama]

Hi,

The value of NCONNECTIONS in src/main/connections.c is the socket
maximum value.

----8<----8<----8<----8<----8<----8<----8<----8<----8<----8<----8<----8<----

#define NCONNECTIONS 128 /* snow needs one per slave node */

----8<----8<----8<----8<----8<----8<----8<----8<----8<----8<----8<----8<----
