**2010-11-06 - Header and POST parsing**

Line differences: [http://wiki.tcl.tk/_/diff?N=27377&V=4&D=0&W=0]; word differences: [http://wiki.tcl.tk/_/diff?N=27377&V=4&D=0&W=1].

[AMG]: I've been holding on to these changes for far too long, and I'm glad to finally publish them.

   * Added separator comments delimiting major sections of the code.
   * Changed usage of [[[dict with] request]] to cut down on indenting.
   * Added many conversion routines:
   ** [[enhtml]]: Encode for HTML.
   ** [[enattr]]: Encode for HTML tag attribute.
   ** [[enpre]]: Encode for HTML <pre>.
   ** [[enquery]]: Encode a query string.
   ** [[dequery]]: Decode a query string into a list.
   ** [[enhex]]: Encode most non-alphanumerics with hexadecimal codes.
   ** [[dehex]]: Decode hexadecimal encoding.
   ** [[enurl]]: Encode for URLs.
   ** [[deurl]]: Decode URL encoding.
   ** [[delist]]: Decode header list encoding.
   ** [[dequote]]: Decode header quoting.
   ** [[deheader]]: Decode HTTP headers.  (!!!)
   * Actually, [[dehex]] already existed, named [[unhex]].  Renamed because [[enhex]] and [[unhex]] are too similar.
   * Modified zone handlers to use new conversion routines, e.g. [[enhtml]].
   * Replaced <td><b> with <th> in [[vars]].
   * Simplified the way [[dirlist]] adds .. to the directory listing.
   * Changed [[applytemplate]] to [[compiletemplate]], which returns the script instead of running it.
   * Made [[template]] cache the result of [[compiletemplate]].
   * Simplified [append]'s arguments in [[compiletemplate]].
   * Added [channel] closure detection to [[getline]] and [[getblock]].
   * Reverted second-chance [[[chan gets]]] in [[getline]], since I'm not convinced it's necessary (see [http://wiki.tcl.tk/27382#pagetoc3c65f636]).
   * Changed the way [[nexthandler]] and [[sendresponse]] pass control back to [[getresponse]].
   * Added accept, post, and rawpost to the request dictionary.
   * Added Accept*: header handling.
   * Added POST handling.
   * [Unset] request dictionary after sending the response to avoid stale data.
   * Correct error report charset.
   * Incorporated [APN]'s [[accept]] fix (see [http://wiki.tcl.tk/27382#pagetoc8c99f371]).

The channel closure detection makes it possible to close connections due to timeouts.  This isn't implemented yet, but it would be nice to harden Wibble against basic [DoS] attacks.
