54b34ccbc5 uhttpd: added uhttpd.docroot 
Passes the document-root to the Lua handler by placing it in uhttpd.docroot.

It could alternatively be placed in env.DOCUMENT_ROOT which would more closely
resemble the CGI protocol; but would mean that it is not available at the time
when the handler-chunk is loaded but rather not until the handler is called,
without any code savings.

bcd8d530d1 Fixed: [PATCH 2/3] uhttpd URL-codec enhancements. 
My apologies, the 2nd of those patches had a syntax error -- that's what
I get for making a last-minute edit, even to the comments, without
testing! :-p

Here is the corrected patch.

Subject: [PATCH] uhttpd URL-codec enhancements.

* uh_urlencode() and uh_urldecode() now return an error condition for
  buffer-overflow and malformed-encoding rather than normal return with corrupt
  or truncated data.  As HTTP request processing is currently implemented, this
  causes a 404 HTTP status returned to the client, while 400 is more
  appropriate.

* Exposed urlencode() to Lua.

* Lua's uhttpd.urlencode() and .urldecode() now raise an error condition for
  buffer-overflow and malformed-encoding rather than normal return with
  incorrect data.

2bfb1e012a uhttpd URL-codec bug fixes. 
* Fixed output-buffer-overflow bug in uh_urlencode() and uh_urldecode() [tested
  input-buffer index against output-buffer length].  In reality, this would not
  typically cause an overflow on decode, where the output string would be
  expected to be shorter than the input string; and uh_urlencode() seems to have
  been unreferenced in the source.

* Fixed bug: uh_urlencode() and uh_urldecode() both read one extra byte from the
  input-string.  While this could manifest in C code, the result was most
  egregious when called from Lua, where it caused an extra null byte to be
  embedded at the end of the output string.

* uh_urlencode() cleanup: removed redundant bitwise-and.
