HS 2.0R2: Clean up debug from libcurl

Browse Source 
Do not truncate CURLINFO entries on first linefeed to get full IN/OUT
headers and data into debug log. Use wpa_hexdump_ascii() if any
non-displayable characters are included. Remove the separate header/data
debug dumps since all that information is now available from the debug
callback.
