This tells the OS to reserve a TX buffer at least the size of the biggest RX frame
expected, for both server and client connections.
In Linux, the OS reserves 2 x the requested amount.
This is aimed at reducing the partial large atomic frame send problem to the point
it's only coming at large atomic frames the OS balks at reserving the size for.
If you have a lot of data to send, it is better to split it into multiple writes,
and use the FIN / CONTINUATION websocket stuff to manage it.
See the "fraggle" test app for example code of how to do that.

It is awfully limiting when you have to set the resource path at compile time.
Instead also allow setting it via the --resource_path command line option.
Also get rid of m4/ and COPYING, it's a copy of LGPL2.1 but without the
exceptions we added in LICENSE.

This should get rid of a valgrind uninitialized report when using extpoll,
and gives a new way to share the poll loop with external sockets.
If a pollfd says it has something, you can just pass it to
libwebsocket_serice_fd() whether it is a socket handled by lws or not.
If it sees it is a lws socket, the traffic will be handled and
pollfd->revents will be zeroed now.
If the socket is foreign to lws, it leaves revents alone. So you can see
if you should service by checking the pollfd revents after letting
lws try to service it.

close() from javascript api in Chrome and Firefox doesn't do the
right thing. It's because the payload is zero-length (with a frame
key...) This fixes it.

here are the problems that I found while compiling libwebsockets with
CMake using as a generator MinGW Makefiles.
1. In http://git.warmcat.com/cgi-bin/cgit/libwebsockets/plain/win32port/win32helpers/gettimeofday.c
Remove spaces around time.h, otherwise it looks for " time.h " and
fails with "No such file ..."
I also needed to comment out
struct timezone
{
int tz_minuteswest; /* minutes W of Greenwich */
int tz_dsttime; /* type of dst correction */
};
It is already declared in mingw's time.h

As discussed here, there's a semi-standardized way to inform
cmake that the install target wants its libs in .../lib64

this patch adds the necessary fiddling

under load, writing packet sizes to the socket that are normally fine
can do partial writes, eg asking to write 4096 may only take 2800 of
it and return 2800 from the actual send.
Until now lws assumed that if it was safe to send, it could take any
size buffer, that's not the case under load.
This patch changes lws_write to return the amount actually taken...
that and the meaning of it becomes tricky when dealing with
compressed links, the amount taken and the amount sent differ. Also
there is no way to recover at the moment from a protocol-encoded
frame only being partially accepted... however for http file send
content it can and does recover now.
Small frames don't have to take any care about it but large atomic
sends (> 2K) have been seen to fail under load.
