* Fix the maximum number of sockets allowed in the session to 2048,
instead of making it relative to sizeof(wsa_event).
The original choice of 2048 was in order to fit the wsa_events array
in the .cygwin_dll_common shared section, but there is still enough
room to grow there to have 2048 sockets on 64-bit as well.
* Return an error and set errno=ENOBUF if a socket can't be created
due to this limit being reached.
