Subject: [PATCH 1/2] Fix for hang when sending large request with SSL enabled

When using SSL, we must use SSL_pending() in addition to/instead of select() to determine whether there is SSL data to be read.
This update makes the SSL_pending() function available and uses is to check for data if select() indicates there is no data.
