- Got rid of ifdef _WIN32 stuff adn moved to plat_ files instead.
- Also, check all calls to lws_zalloc, was potential failure on WIN32
- Made context destory enable to destroy a half inited context as well. This way I got get rid of some of the error handling complexity in libwebsocket_create_context
- Added TODOs for some potential problems I see where things might be leaking and such
At least some win32 uses an opaque pointer for fd that is not
an ordinal like it is in unix.
Resurrect the old hashtable management for that platform to use
instead, and introduce a helper to get the wsi from the fd "somehow".

This replaces gethostbyname in libwebsockets_get_peer_addresses and
in the client handshake path.
There's one left in lws-plat-win but that can be done another time.
Let's see how much damage that did to the cross-platform and option
builds...

If the remote HTTP client closes the connection before serving commences, the
only notification client code receives is LWS_CALLBACK_WSI_DESTROY. This commit
gives LWS_CALLBACK_CLOSED_HTTP as well, as would happen if HTTP serving had
already commenced.
This adds npn / alpn support if your openssl can handle it.
Then, browsers that understand alpn will by default
negotiate http/1.1 and work as normal.
Clients that understand http2.0 can negotiate h2-14 and
use the basic but working http2.0 support automatically

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
This gets rid of all the platform-dependent #ifdef stuff and
migrates it into the new lws-plat-xxx.c files.
These are then included in a one-time test in libwebsockets.c
according basically to Windows or not.
The idea is from now on, all Windows-specific code should go in
lws-plat-win.c, where any kind of Windows perversion like DWORD
is fine.
Any new functions going in there should be named lws_plat_...
and be defined in all the lws-plat-xxx.c file (currently just
win32 and unix platforms are supported).
