In de9eef30, the error number assigned to WSAENOTSOCK was EFAULT, but
zmq.cpp:919 expects an ENOTSOCK in this case.

Code cleanup

Exclude test_abstract_ipc from non-Linux builds

Corrected installer source path for VS pdb debug symbols file.  Removed ...

Refresh VS 2010/2012 projects and NuGet templ for recent VS2013 updates.

handle WSAEADDRINUSE in tcp_connecter_t::connect

(accidentially used my preferred style)

As mentioned on the mailing list, Windows may return WSAEADDRINUSE when binding
(reconnecting) to a port. Added this to the handled error codes as Pieter
suggested.

Remove copy of platform.hpp for MSVC VS2013 builds

Restore unpathed references to platform.hpp for cmake builds

Exclude MSVC temp files regardless of where they are in builds/msvc

VS set switch /Z7 in debug static (DebugLIB/DebugLTCG) base props.

Extend zmq::wsa_error_to_errno()

The list of error codes is taken from zmq::wsa_error_no(). Most of the
new WSA error codes result in EFAULT, but some return a more specific
value (even EAGAIN).

Fixes #1071

Update VS import props to allow delinking, reset PDB out path change.
