Check if client half-closed TCP connection if POLLHUP is received.
This more robustly handles if client called shutdown(fd, SHUT_WR).
This patch reverts commit:ab05eb7c which should now be handled properly.
(Time will tell.)

Set server.stream-response-body = 1 or server.stream-response-body = 2
to have lighttpd stream response body to client as it arrives from the
backend (CGI, FastCGI, SCGI, proxy).
default: buffer entire response body before sending response to client.
(This preserves existing behavior for now, but may in the future be
changed to stream response to client, which is the behavior more
commonly expected.)

to detect client disconnect. Do so even when waiting on backend,
and not polling for POLLRD or POLLWR on client connection.
This reduces unnecessary load on backends when backends are slow
to respond and client has given up waiting.

FastCGI performance on high load
These should all be non critical:
* memory leaks on startup in error cases (which lead to
immediate shutdowns anyway)
* http_auth/ldap: passing uninitialized "ret" to ldap_err2string
* sizeof(T) not matching the target pointer in malloc/calloc calls;
those cases were either:
* T being the wrong pointer type - shouldn't matter as long as all
pointers have same size
* T being larger than the type needed
* mod_accesslog: direct use after free in cleanup (server shutdown);
could crash before "clean" shutdown
* some false positives (mod_compress, mod_expire)
* assert(srv->config_context->used > 0); - this is always the case,
as there is always a global config block

The proper way to declare a function taking no parameters isn't:
foo bar();
But this instead:
foo bar(void);

i hope it helps with merging stuff back to 1.5
