This implements clean client and server close for mux child connections,
and deals with accounting for parent child lists.
The mux link can then survive constant connection bringup and teardown
found in the new test client.

This is initial x-google-mux support. It's disabled by default
since it's very pre-alpha.
1) To enable it, reconfigure with --enable-x-google-mux
2) It conflicts with deflate-stream, use the -u switch on
the test client to disable deflate-stream
3) It deviates from the google standard by sending full
headers in the addchannel subcommand rather than just
changed ones from original connect
4) Quota is not implemented yet
5) Close of subchannel is not really implemented yet
6) Google opcode 0xf is changed to 0x7 to account for
v7 protocol changes to opcode layout
However despite those caveats, in fact it can run the
test client reliably over one socket (both dumb-increment
and lws-mirror-protocol), you can open a browser on the
same test server too and see the circles, etc.

you have your makefiles set up to treat warnings as errors, and my gcc
4.4.5 (64 bit) compiler generates 3 warnings that need fixing:
(that sprintf() one is a real bug.. if ext_name contains formatting
characters you are looking at a potential segv).

This goes through the extentsions the client requested, selects the ones
that we support at the server, and then further calls back to the appropriate
protocol callback in user code to check it's OK to actually use that
extension in this context. If it is (callback unhandled == it is) then
it's added to the list of extensions sent back to the client.
Accepted extensions are also added to the connection's active extension
list and the private "user" memory allocation for the extension context is
done and bound to the connection.

This adds win32 build compatability to libwebsockets.
The patch is from Peter Hinz, Andy Green has cleaned it up a bit and
possibly broken win32 compatability since I can't test it, so there
may be followup patches. It compiles fine under Linux after this
patch anyway.
Much of the patch is changing a reserved keyword for Visual C compiler
"this" to "context", but there is no real C99 support in the MSFT
compiler even though it is 2011 so C99 style array declarations
have been mangled back into "ancient C" style.
Some windows-isms are also added like closesocket() but these are
quite localized. Win32 random is just using C library random() call
at the moment vs Linux /dev/urandom. canonical hostname detection is
broken in win32 at the moment.

This adds 05 support, and -v switches on test-client and test-ping
to allow setting their ietf protocol version to 4 or 5.
It also optimizes the masking to us a function pointer, which
takes some conditionals out of the fast path.
