Update lighttpd to 1.4.20.

This contains security fix: http://trac.lighttpd.net/trac/ticket/1774


- 1.4.20 -

  * Fix mod_compress to compile with old gcc version (#1592)
  * Fix mod_extforward to compile with old gcc version (#1591)
  * Update documentation for #1587
  * Fix #285 again: read error after SSL_shutdown (thx marton.illes@balabit.com) and clear the error queue before some other calls (CVE-2008-1531)
  * Fix mod_magnet: enable "request.method" and "request.protocol" in lighty.env (#1308)
  * Fix segfault for appending matched parts if there was no regex matching (just give empty strings) (#1601)
  * Use data_response_init in mod_fastcgi x-sendfile handling for response.headers, fix a small "memleak" (#1628)
  * Don't send empty Server headers (#1620)
  * Fix conditional interpretation of core options
  * Enable escaping of % and $ in redirect/rewrite; only two cases changed their behaviour: "%%" => "%", "$$" => "$"
  * Fix accesslog port (should be port from the connection, not the "server.port") (#1618)
  * Fix mod_fastcgi prefix matching: match the prefix always against url, not the absolute filepath (regardless of check-local)
  * Overwrite Content-Type header in mod_dirlisting instead of inserting (#1614), patch by Henrik Holst
  * Handle EINTR in mod_cgi during write() (#1640)
  * Allow all http status codes by default; disable body only for 204,205 and 304; generate error pages for 4xx and 5xx (#1639)
  * Fix mod_magnet to set con->mode = p->id if it generates content, so returning 4xx/5xx doesn't append an error page
  * Remove lighttpd.spec* from source, fixing all problems with it ;-)
  * Do not rely on PATH_MAX (POSIX does not require it) (#580)
  * Disable logging to access.log if filename is an empty string
  * Implement a clean way to open /dev/null and use it to close stdin/out/err in the needed places (#624)
  * merge spawn-fcgi changes from trunk (from @2191)
  * let spawn-fcgi propagate exit code from spawned fcgi application
  * close connection after redirect in trigger_b4_dl (thx icy)
  * close connection in mod_magnet if returned status code
  * fix bug with IPv6 in mod_evasive (#1579)
  * fix scgi HTTP/1.* status parsing (#1638), found by met@uberstats.com
  * [tests] fixed system, use foreground daemons and waitpid
  * [tests] removed pidfile from test system
  * [tests] fixed tests needing php running (if not running on port 1026, search php in env[PHP] or /usr/bin/php-cgi)
  * fixed typo in mod_accesslog (#1699)
  * replaced buffer_{append,copy}_string with the _len variant where possible (#1732) (thx crypt)
  * case insensitive match for secdownload md5 token (#1710)
  * Handle only HEAD, GET and POST in mod_dirlisting (same as in staticfile) (#1687)
  * fixed mod_secdownload problem with unsigned time_t (#1688)
  * handle EAGAIN and EINTR for freebsd sendfile (#1675)
  * Use filedescriptor 0 for mod_scgi spawn socket, redirect STDERR to /dev/null (#1716)
  * fixed round-robin balancing in mod_proxy (#1715)
  * fixed EINTR handling for waitpid in mod_fastcgi
  * mod_{fast,s}cgi: overwrite environment variables (#1722)
  * inserted many con->mode checks; they should prevent two modules to handle the same request if they shouldn't (#631)
  * fixed url encoding to encode more characters (#266)
  * allow digits in [s]cgi env vars (#1712)
  * fixed dropping last character of evhost pattern (#161)
  * print helpful error message on conditionals in global block (#1550)
  * decode url before matching in mod_rewrite (#1720)
  * fixed conditional patching of ldap filter (#1564)
  * Match headers case insensitive in response (removing of X-{Sendfile,LIGHTTPD-*}, catching Date/Server)
  * fixed bug with case-insensitive filenames in mod_userdir (#1589), spotted by "anders1"
  * fixed format string bugs in mod_accesslog for SYSLOG
  * replaced fprintf with log_error_write in fastcgi debug
  * fixed mem leak in ssi expression parser (#1753), thx Take5k
  * hide some ssl errors per default, enable them with debug.log-ssl-noise (#397)
  * do not send content-encoding for 304 (#1754), thx yzlai
  * fix segfault for stat_cache(fam) calls with relative path (without '/', can be triggered by x-sendfile) (#1750)
  * fix splitting of auth-ldap filter
  * workaround ldap connection leak if a ldap connection failed (restarting ldap)
  * fix auth.backend.ldap.bind-dn/pw problems (only read from global context for temporary ldap reconnects, thx ruskie)
  * fix memleak in request header parsing (#1774, thx qhy)
  * fix mod_rewrite memleak/endless loop detection (#1775, thx phy - again!)
  * use decoded url for matching in mod_redirect (#1720)
