623a98dab0 unionize mutually exclusive wsi members
Large chunks of struct libwebsocket members actually have a mutually
exclusive lifecycle, eg, once the http headers are finished they sit
there unused until the instance is destroyed.

This makes a big improvement in memory efficiency by making four
categories of member: always needed, needed for header processing,
needed for http processing, and needed for ws processing.  The last
three are mutually exclusive and bound into a union inside the wsi.

Care needs taking now at "union transitions", although we zeroed down
the struct at init, the other union siblings have been writing the
same memory by the time later member siblings start to use it.  So
it must be cleared down appropriately when we cross from one
mutually-exclusive use to another.

5738c0e838 remove all support for pre v13 protocols
Since v13 was defined as the released ietf version the older versions
are deprecated.  This patch strips out everything to do with the older
versions and gets rid of the option to send stuff unmasked.

The in-tree md5 implementation is then also deleted as nothing needs
it any more, 1280 loc are shed in all
