* [fix] Several fixings applied to allow compiling noPoll on Windows (Windows 7 64 tested).
Renamed parameters using "interface" keyword. Removed conditionally binding interface
code so it is not available on windows (until we have support for it). Added header
definitions for nopoll_config_win32/win64.h to include headers for SSL/TLS includes.
Fixed compilation errors in regression tests.
* [fix] Added some additional nopoll_base64_encode cleanups to ensure
all resources are released under error. Checked call to flush internal BIO.
* [fix] Fixed compilation warning at nopoll_conn.c (due to unused variable when
SHOW_DEBUG_LOG isn't defined).
* [fix] Updated regression code to detect some cases where listener is not
able to send at a particular moment.
