RetroShare/libretroshare/src/tests/pqi/net_test.cc
drbob 648e15bcf7 Found cause of OSX network resets / lost connections: inet_ntoa is not thread-safe.
* Added thread-safe rs_inet_ntoa function (util/rsnet.cc)
 * Switched all calls to this function (most of the changes)
 * Modified getLocalInterfaces() and getPreferredInterface() to avoid string conversions.
   - NB: Modified windows functions too, but unable to test (hope it compiles!)

Also:
 * Added  EVP_CIPHER_CTX_rand_key() replacement function for old versions of SSL (pre 0.9.8)  (for OSX 10.5)
   - NB: This code should be reworked to remove these calls anyway.
 * Updated tests/pqi to handle above changes.
