Malformed encoding in chunked resposes

[errno]

I was writing a CGI function which generates quite big responses (>2k). So it utilizes consecutive httpdSend() calls and HTTPD_CGI_MORE return code.
At some point I've stumbled upon corrupted responses. curl says Malformed encoding found in chunked-encoding.

Further digging revealed that I managed to fill conn->priv.sendBuff to the brim (exactly 2048 bytes) before returning from the function with HTTPD_CGI_MORE. That, in turn, caused a problem in httpdFlushSendBuffer(), because there is no room for closing a chunk with \r\n, and chunk length is calculated incorrectly.

I'm going to try to fix this issue myself. If I succeed I'll open a pull request.

That was relatively easy. I hope my approach is acceptable. And my changes didn't break other stuff :)

Merged (better late than never right?). Thanks.
BTW, maybe #93 is related to this issue. I'll test that again now that this is merged.

Hurray! It's just the right time.
I've returned to working on the project in which I discovered this issue a few days ago, so now I can switch back from my fork :)
