With the introduction of subscription forwarding, the first message sent
on a PUB socket using a unidirectional transport (e.g. PGM) is always
lost due to the "subscribe to all" being done asynchronously.

This patch fixes the problem and also refactors the code to have a single
point where the "subscribe to all" is performed.

This patch fixes the problem described in LIBZMQ-205. The assertion itself
is probably caused by previously queued POLLIN events arriving after POLLIN
has been disabled on the socket.

The following additional bugs have been fixed as part of debugging this
problem:

- pgm_receiver_t does not flush messages written to the session in all
  cases which can lead to a stalled reader. Add calls to session->flush ()
  in the appropriate places.

- ensure to restart polling when a pending message is flushed in
  activate_in ().

Opening any PGM socket gives this assertion. The problem is in
pgm_sender_t::plug() which is incorrectly testing the return value from
session::write().

When (X)SUB socket is being shut down there may be pending
outbound subscription commands in the pipes. In such case
we want to close the socket immediately instead of waiting
for the commands to be sent.

When polling on XREP socket in incoming message part was prefetched,
but not the identity of sender. The problem is fixed by this patch.

These include configurations for both Win32 and x64 platforms. All project
settings have been normalised in property sheets (the ".props" files under
builds/msvc/properties) to simplify maintenance. Build artefacts are all
generated in platform-specific subfolders of bin, lib and obj directories.

Also enables the use of precompiled headers with MSVC10.

This significantly reduces the time required to compile libzmq with Visual
Studio on Windows. It should have no impact on other platforms.

This patch fixes the bug, and also an identical problem in tcp_connecter
which has not hit people since TCP connect() usually completes via the
asynchronous code path (poll, out_event).

Mercurial does not have built-in support for converting line-endings. This is a
settings file for hg eol (http://mercurial.selenic.com/wiki/EolExtension), an
extension that replicates the behaviour of git with core.autocrlf=true.

Mercurial uses Python regex syntax by default in its .hgignore files. Adding
this line to .gitignore overrides that setting, so hg-git users can just create
a hardlink to it (e.g "mklink /H .hgignore .gitignore" on Windows) to use it.
