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

Since struct lws (wsi) now has his own context pointer,
we were able to remove the need for passing context
almost everywhere in the apis.
In turn, that means there's no real use for context being
passed to every callback; in the rare cases context is
needed user code can get it with lws_get_ctx(wsi)

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 adds a public API variant of the header copy api that lets you
choose which fragment you want copied.
Normally you want the existing one that aggregates the fragments.
But it can be useful to get each part in turn (that corresponds to
the content provided by each duplicated header normally).

Now we bit the bullet and gave each wsi an lws_context *, many
internal apis that take both a context and wsi parameter only
need the wsi.
Also simplify parser code by making a temp var for
allocated_headers * instead of the longwinded
dereference chain everywhere.

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.

Between changing to lws_ a few years ago and the previous two
patches migrating the public apis, there are only a few
internal functions left using libwebsocket_*.
Change those to also use lws_ without regard to compatibility
since they were never visible outside the library.

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.

This is a squashed commit from https://github.com/andrew-canaday/libwebsockets,
dev/http_keepalive branch (strategies changed a few times, so the commit
history is clutteread). This branch is submitted for clarity, but the other
can be used as a reference or alternative.
* added **enum http_version** to track HTTP/1.0 vs HTTP/1.1 requests
* added **enum http_connection_type** to track keep-alive vs close
* replaced content_length_seen and body_index with **content_remain**
* removed **post_buffer** (see handshake.c modifications)
* removed post_buffer free
* switch state to WSI_TOKEN_SKIPPING after URI is complete to store version
* delete *spill* label (unused)
* add vars to track HTTP version and connection type
* HTTP version defaults to 1.0
* connection type defaults to 'close' for 1.0, keep-alive for 1.1
* additional checks in **cleanup:** label:
* if HTTP version string is present and valid, set enum val appropriately
* override connection default with the "Connection:" header, if present
* set state to WSI_STATE_HTTP_BODY if content_length > 0
* return 0 on HTTP requests, unless LWS_CALLBACK_HTTP indicates otherwise
* add vars to track remaining content_length and body chunk size
* re-arrange switch case order to facilitate creation of jump-table
* added new labels:
* **read_ok**: normal location reach on break from switch; just return 0
* **http_complete**: check for keep-alive + init state, mode, hdr table
* **http_new**: jump location for keep-alive when http_complete sees len>0
* after libwebsocket_parse, jump to one of those labels based on state
* POST body handling:
* don't bother iterating over input byte-by-byte or using memcpy
* just pass the relevant portion of the context->service_buffer to callback
- added options to minilex.c
- regenerated lextable.h
- added WSI_TOKEN_OPTIONS_URI to libwebsockets.h
- tweaked parsers.c to accommodate OPTIONS token
- tweaked server.c to set uri_ptr and uri_len for HTTP callback on OPTIONS as well
