Support a new boolean property `cors` which - if set to true - causes the
dispatcher to positively answer CORS OPTIONS requests after authentication
without actually running the dispatching target.

Decode the HTTP message bodies of any request carrying a Content-Length
header, not just those in POST requests.
This allows handling parameters in other methods, OPTIONS in particular.

Restore the old luci.http behaviour of converting repeated POST params into
single tables holding all values instead of letting each repeated parameter
overwrite the value of the preceeding one.
Fixes, among other things, the handling of CBI dynamic list values.

Introduce luci.model.uci.set_session_id() and luci.model.uci.get_session_id()
to set and get the effective session ID respectively.
When a session ID is set, it is sent as `ubus_rpc_session` attribute to rpcd,
causing it to use per-session change directories, isolating LuCI changes from
the global system uci state.

Also adjust the dependencies of components depending on these classes and

Signed-off-by: Jo-Philipp Wich <jo@mein.io>
With only the decoder routines remaining in luci.http.protocol, it makes no
sense to keep the low level protocol class around, so fold the remaining code
into the central luci.http class.
Also adjust the few direct users of luci.http.protocol accordingly.

Use the liblucihttp provided multipart and x-www-urlencoded body parsers
and drop the old Lua parsing code.
The C based data parsers are way faster than their old Lua counterparts
while producing less string garbage and more correct results.
While refactoring the luci.http.protocol code, also drop unused functions
and dead code, heavily reducing the module size.

This 404 error template rendering has been broken for a long time due to bad
function environment level in luci.template when invoking the rendering from
the toplevel dispatcher context.
Fix this issue by adding a local function indirection, essentially adding an
additional stack frame.

Instead of attempting to access the request environment directly (which does
not work anyway using the CGI SGI), use the already sanitized
dispatcher.context.request property to print out the not found url.
Signed-off-by: Jo-Philipp Wich <jo@mein.io>
It is possible to inject unescaped markup using a double encoded null byte
via PATH_INFO on certain leaf nodes.
Since there is no legitimate reason to handle null bytes in any part of the
requested url, simply skip over such bytes when parsing the PATH_INFO value.

Introduce a get_state() function which can be used to access legacy
uci state variables. This is usually not needed anymore but some

The lookup function takes multiple, possibly malformed path fragments,
splits them on slashes, constructs a temporary path and looks up the
result in the dispatch tree.
If a matching node has been found, the function will return both the
node reference and the canonical url to it.
If no corresponding node is found, the function returns nil.

Due to the fact that luci.model.cbi reacts on any "cbi.submit" value while

Introduce a new template property FULL_REQUEST_URI which returns the full
canonicalized request URL built from SCRIPT_NAME, PATH_INFO and QUERY_STRING.
This new property is safer to use compared to using the raw REQUEST_URI CGI
environment variable directly as this value is essentially untrusted user
input which may contain embedded escaped slashes, double forward slashes and
other oddities allowing XSS exploitation or request redirection.

The /etc/ethers file may contain any number of white space characters
