Fix builds/msvc/Makefile.am to include all properties files in the build

I attempted to fix up the properties files manifests in the Makefile,
but neglected the end-of-line escape characters.  It was good enough
to pass whatever make dist on Linux did, but I had no Windows build
env to test in.  The broken change was in commit de4a442.

Add support for POLLPRI flag.

This commit adds a ZMQ_POLLPRI flag that maps to poll()'s POLLPRI
flag.
This flags does nothing for OMQ sockets. It's only useful for raw
file descriptor (be it socket or file).
This flag does nothing if poll() is not the underlying polling
function. So it is Linux only.
