This adds support for multithreaded service to lws without adding any
threading or locking code in the library.
At context creation time you can request split the service part of the
context into n service domains, which are load-balanced so that the most
idle one gets the next listen socket accept.
There's a single listen socket on one port still.
User code may then spawn n threads doing n service loops / poll()s
simultaneously. Locking is only required (I think) in the existing
FD lock callbacks already handled by the pthreads server example,
and that locking takes place in user code. So the library remains
completely agnostic about the threading / locking scheme.
And by default, it's completely compatible with one service thread
so no changes are required by people uninterested in multithreaded
service.
However for people interested in extremely lightweight mass http[s]/
ws[s] service with minimum provisioning, the library can now do
everything out of the box.
To test it, just try
$ libwebsockets-test-server-pthreads -j 8
where -j controls the number of service threads

- Mainly symbol length reduction
- Whitespace clean
- Code refactor for linear flow
- Audit @Context for API docs vs changes

Extend the cleanout caused by wsi having a context pointer
into the public api.
There's no point keeping the 1.5 compatibility work,
we have changed the api in several places and
rebuilt wasn't going to be enough a while ago.

This makes the URI argument processing split each parameter into
a "fragment". Processing header content as fragments already exists
in lws, because it's legal to deliver header content by repeating
the header.
Now there's an api to access individual fragments, also add the
code to the test server to print each URI argument separately.
Adapt attack.sh to parse the fragments.

This nukes all the oldstyle prefixes except in the compatibility code.
struct libwebsockets becomes struct lws too.
The api docs are updated accordingly as are the READMEs that mention
those apis.

Change all internal uses of rationalized public apis to reflect the
new names.
Theer are a few things that got changed as side effect of search/replace
matches, but these are almost all internal. I added a compatibility define
for the public enum that got renamed.
Theoretically existing code should not notice the difference from these
two patches. And new code will find the new names.
