To use, you need to both
- cmake ---> -DLWS_USE_LIBEV=1
- info->options must have LWS_SERVER_OPTION_LIBEV set when creating the context
this is so a single library can be built for distros to support apps that use
normal polling and apps that use libev polling.
Also change from looking at wsi->truncated_send_malloc to see if we are in the middle of
dealing with a truncated send to looking for nonzero wsi->truncated_send_len

Add a special implementation with CreateFile(), ReadFile() and CloseFile()
for serving HTTP file request to allow compilation on all Windows platforms.
Add a new function to get the current time in microseconds, since gettimeofday() does not exist on Windows.
Keep the current implementation for the test applications.
C89 which Microsofts compiler only support does not allow variable
declarations anywhere but at the start of a scope.
Also, only try to copy the test-server files if they actually exists. For
instance the OpenSSL cert generation fails if you run cmake under the git
bash shell on Windows (won't work with the unix method either) so that
file will be missing... This would result in a compilation error when
tests where turned on.
To enable this code you need to force LWS_HAS_PPOLL to de defined.
#defining it at the top of libwebsockets.c is enough.

This provides a single place for pollfd event changing,
external locking for that and extpoll management.
It saves about 85 lines of duplication and simplifies the callers.

This adds two new callbacks in protocols[0] that are optional for allowing limited thread
access to libwebsockets, LWS_CALLBACK_LOCK_POLL and LWS_CALLBACK_UNLOCK_POLL.
If you use them, they protect internal and external poll list changes, but if you want to use
external thread access to libwebsocket_callback_on_writable() you have to implement your
locking here even if you don't use external poll support.
If you will use another thread for this, take a lot of care about managing your list of
live wsi by doing it from ESTABLISHED and CLOSED callbacks (with your own locking).

If enabled one listening socket will accept both SSL and plain HTTP connections.
Do not enable if you regard SSL handshake as some kind of security, eg, use
client-side certs to restrict access.
AG: changed flag names, added extra comments, changelog, add -a in test server

This patch deploys the truncated send work to buffer output in case
either send() or the SSL send return a temporary "unable to send"
condition even though they signalled as writeable.
I added a by-default #if 0 test jig which enforces only half of what
you want to send is sendable, this is working when enabled.
One subtle change is that the pipe reports choked if there is any
pending remaining truncated send. Otherwise it should be transparent.
Hopefully...
