This is important since this stuff is in publicly included headers
and even though the usage of the WSAPoll API is a runtime decision
the public headers may be used in code that needs to build with
_WIN32_WINNT=0x0501 to support WinXP.
When building a project using libwebsockets with that define set
to 0x0501 winsock.h will not define the WSAPOLLFD struct causing that
project to fail to compile.
This adds win32 build compatability to libwebsockets.
The patch is from Peter Hinz, Andy Green has cleaned it up a bit and
possibly broken win32 compatability since I can't test it, so there
may be followup patches. It compiles fine under Linux after this
patch anyway.
Much of the patch is changing a reserved keyword for Visual C compiler
"this" to "context", but there is no real C99 support in the MSFT
compiler even though it is 2011 so C99 style array declarations
have been mangled back into "ancient C" style.
Some windows-isms are also added like closesocket() but these are
quite localized. Win32 random is just using C library random() call
at the moment vs Linux /dev/urandom. canonical hostname detection is
broken in win32 at the moment.
