Update NSS libSSL to NSS_3_15_BETA2.

  * This file essentially replicates NSPR's source for the functions that
  * map system-specific error codes to NSPR error codes.  We would use 
  * NSPR's functions, instead of duplicating them, but they're private.
  * As long as SSL's server session cache code must do platform native I/O
  * to accomplish its job, and NSPR's error mapping functions remain private,
  * this code will continue to need to be replicated.
