Log message:
Fix uploads using chunked transfer-encoding
The current code is broken so rework server_read_httpchunks() to properly
implement chunked transfer-encoding. Chunked uploads only matter for
fastcgi handlers, so adjust them to operate with chunked uploads.
The problem is that the CGI spec mandates that CONTENT_LENGTH is set
but for chunked transfers the content-length header is actually not
allowed. Both fastcgi and cgi don't really need CONTENT_LENGTH since the
data is passed via FCGI_STDIN messages or a pipe and in both cases EOF
can be signaled just fine. Still some cgi/fastcgi handlers depend on the
presence of CONTENT_LENGTH and so those fail to process such chunked
uploads. For this reason add a config option to opt-in for chunked
uploads but by default any upload with transfer-encoding chunked will
result in a HTTP 400 error.
