More specific checks on contents of array lists. Each module using
lists now does better checking on the types of values in the list
(strings, integers, arrays/lists)
This helps prevent misconfiguration of things like cgi.assign,
fastcgi.server, and scgi.server, where source code might be
served as static files if parenthesis are misplaced.

It is still not a good idea for backend to send Transfer-Encoding unless
backend is mod_proxy, and mod_proxy should not currently receive chunked
response since mod_proxy sends HTTP/1.0 request.
If mod_proxy is changed to sent HTTP/1.1 request, then lighttpd would
need to check if client is HTTP/1.0 and would need to de-chunk and
remove any other transfer-codings if not supported by next-hop.

The (misnamed) connection_reset hook is always called after a request,
whether request completes or is aborted, and whether keep-alive or not,
so no needed to repeat the same function in the handle_connection_close
hook.
[mod_deflate] skip deflate if 1 min loadavg too high
deflate.max-loadavg = "3.50" # express value as string of float num
[mod_compress] skip compression if 1 min loadavg too high
compress.max-loadavg = "3.50" # express value as string of float num
Feature available on BSD-like systems which have getloadavg() in libc
Note: load average calculations are different on different operating
systems and different types of system loads, so there is no value that
can be recommended for one-size-fits-all.

mod_deflate and mod_compress now provide data for mod_accesslog
"%{ratio}n%%" log format to log compression ratio
Implementation detail: compression ratio is stored in con->environment
since lighttpd does not currently have concept of module notes, which is
from where %{VARNAME}n originates. In the future, this might change in
lighttpd, so be sure to use %{ratio}n%% and not %{...}e for this info.

mod_deflate performs prefix match of deflate.mimetypes against the
response Content-Type. Therefore "text/" will make all text/*
mimetypes. This commit permits admin to specify "text/*" in
deflate.mimetypes = ("text/*")
and mod_deflate will treat it as "text/". This is done only when the
'*' is the last char in the mimetype.
fix potential NULL pointer dereference in mod_deflate.c
remove logically dead code in connection-glue.c
add coverity annotations to see if some issues will be reclassified
lots of fixes and improvements
limitations: see comments at top of mod_deflate.c
missing functionality: encode streaming response
(module currently requires response be collected before being sent)
potential functionality: addition of compressed file cache would
allow mod_deflate to fully supplant mod_compress in lighttpd 1.4.x
