Subject: [PATCH] SSL: Disable support for SSLv2 and SSLv3.

Subject: [PATCH] Enable usage of ancient OpenSSL.

Yes people should be upgrading their OpenSSL, but there are still old versions without Heartbleed out there being used...

Subject: [PATCH] BUGFIX: Failed to get proper output dir for test-server

When creating the directory where to put the files needed by the test-server CMake would fail because it tried to create the directory /../share/libwebsockets-test-server, which is not possible. This happens since the TARGET_FILE_DIR for the test-server is not fetched properly.

Be sure to invoke *lws_free_header_table*:

 * Just prior to freeing a session

Reset hdr_parsing_completed for WSI_STATE_HTTP:

This fixes a bug where a client issues two GET requests on the same connection
(keep-alive). If the second request is split into two reads, the
hdr_parsing_complete flag gets us into trouble by ending the request read two
early and giving us bogus data.

Fix TCP keepalive use in UNIX systems

Keep-alive: disable timeout and let TCP ka kill.

This is required for streaming HTTP connections.
Not sure if there's a more graceful way to handle this
(maybe resetting the timeout in the 'send'-side code?

Make sure headers are parsed before proceeding.

Only check for '?' URI args during URI path parse

handle client protocol lists properly

We fail to deal with lists of protocols sent by the client
by picking one from the list properly.  This fixes that and

Don't need 'content_remain' in libwebsocket_read

HTTP Version, Keep-alive support, No-copy POST

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
