async-dns has to keep a listener on udp:53, but its tag doesn't really give
a clue what it is
[1534033|wsisrv|0|adopted]
this patch improves it and moves the decision about putting the server wsi
in SERVER or MUX group to the caller instead of guessing from the desc
name.

When the client goes away, on some platforms all we get is POLLIN revent
stuck on... we have to read it to find out a zero length result and
understand it's gone.
Add SSE mode's DOING_TRANSACTION to the list of states we will read for.
Added the ability to get additional form parameters with unknown names in the form parameters parser lws_spa. The example of using the form parameters parser has been updated. Fixed bug of double freeing memory in the example.
The FREERTOS plat has its own h2 SETTINGS, but although they are used, they
get overridden with the lws default SETTINGS during pt init.
Let's not do that if someone else has already touched the context set.
If there's ssl pending and stuff in the buflist, it was observed we can
spin if the buflist is not cleared due to wsi state.
Add a sanity check for the number of times we will try to deal with that
before dropping the conn.
Add -Wextra (with -Wno-unused-parameter) to unix builds in addition to
-Wall -Werror.
This can successfully build everything in Sai without warnings / errors.
On some platforms AF_INET and AF_INET6 must be listened for on separate
sockets. Adapt the vhost server creation code to use the new support for
multiple listen sockets per vhost to create up to two listen sockets for
AF_INET and AF_INET6.
It refactors how the decision about the AF is made and propagated so
there's only one place for it.
Some platforms need two sockets with AF_INET and AF_INET6 to listen to both
protocols.
This patch changes the single listen socket each vhost could previously
handle to become an lws_dll2 and adapts the related code to handle them as
a linked-list rather than as a singleton.
The next patch adapts the listen / server code to create multiple listen
wsi for vhosts listening on multiple ip protocols.
Until now although we can follow redirects, and they can promote the
protocol from h1->h2, we couldn't handle h2 wsi reuse since there are many
states in the wsi affected by being h2.
This wipes the related states in lws_wsi_reset() and follows the generic
wsi close flow before deviating into the redirect really close to the end,
ensuring we cleaned out evidence of our previous life properly.
h2->h2 redirects work properly after this.
The max number of redirects is increased from 3 -> 4 since this was seen in
the wild with www and then geographic-based redirects.
