Fix corner case in NTLM authentication (trac #172)
The problem is located in the file proxy.c within
"establish_http_proxy_passthru": To keep buffers small long
base64-encoded NTLM-Strings are truncated.
But the truncating is done on a wrong place: base 64 strings can be
cut every 4 chars. the buffer is 128 bytes - including the terminating
\0, so the usable data is only 127 bytes. And decoding a 127 char
base64 string fails... this is why the ntlm authentication fails in
certain cases (long strings)...
