When using http/1.1+ keepalive and mounts, the relationship between
a connection and a protocol becomes dynamic. The same connection might
visit different bits of the url space served by different mounts using
different protocols.
This patch ensures protocols can cleanly manage their per-connection
allocations by using the following callbacks when the protocol changes
LWS_CALLBACK_HTTP_BIND_PROTOCOL
LWS_CALLBACK_HTTP_DROP_PROTOCOL
For example if the pss wants to malloc stuff at runtime, it should do it
in LWS_CALLBACK_HTTP_BIND_PROTOCOL or later, and clean it up in
...DROP_PROTOCOL.

This gives protocols a way to talk to each other via per-vhost callbacks,
one per protocol (including the sender).

This adds
- simple lws_urlencode()
- simple lws_urldecode()
- simple lws_sql_purify
Those expect the data to all be there and process it up until
the first '\0'.
There is also a larger opaque apis for handling POST_BODY urldecode. To
enable these, you need to give cmake -DLWS_WITH_STATEFUL_URLDECODE=1 (or
arrange any larger feature that relies on it sets that in CMakeLists.txt)
- stateful urldecode with parameter array
These have create / process / destroy semantics on a struct that maintains
decode state.
Stateful urldecode is capable of dealing with large POST data in multiple
POST_BODY callbacks cleanly, eg, file transfer by POST.
Stateful urldecode with parameter array wraps the above with a canned
callback that stores the urldecoded data and indexes them in a pointer
array matching an array of parameter names.
You may also pass it an optional callback when creating it, that will recieve
uploaded file content.
The test html is updated to support both urlencoded and multipart forms,
with some javascript to do clientside validation of an arbitrary 100KB
file size limit (there is no file size limit in the apis).

The latest Android SDK updates deprecate the shell script
used to create a standalone toolchain. This patch updates the Makefile for
the Android test-client to use the new Python script to create the standalone
toolchains.
Server ipv6 support disable is now controlled by vhost->options rather
than context->options, allowing it to be set per-vhost.

Adds a convenient way to directly get the value of a URL
argument like ...?x=y&v=1, regardless of position in the
parameter list.

Otherwise lwsws started at boot on a system without an RTC
may feel it was started in 1970, and when the clock is set
by ntpd a little later, has been up for 16,000 days...

This makes it easy for user code to choose the size of the per-thread
buffer used by various things in lws, including file transfer chunking.
Previously it was 4096, if you leave info.pt_serv_buf_size as zero that
is still the default.
With some caveats, you can increase transfer efficiency by increasing it
to, eg, 128KiB, if that makes sense for your memory situation.
