Changes from 25/7/2014.

Changelog:
2014.07.25:
- Fixed an obscure bug in "RTPInterface::sendPacket()" when sending a packet over TCP.
  (Thanks to "ChaSeop Im" for reporting this.)
- Added "-DXLOCALE_NOT_USED" to the "COMPILE_OPTS" line in the "config.solaris*" configuration
  files, because someone claimed that this was necessary in order to build the code for Solaris.
