The connect_async() calls would never terminated when an application side
proxy was being used. Note we also skip over TLS handshake in this case,
as the application may have to do some proxy handshake before.
The proxy address was not cleared between each attempt. That would lead
to leak or worse, trying to do the proxy handshake on the final
destination address. To make all this safer, I have regroup all the cleanup
where the iterations starts.

Include the hostname (or proxy hostname if it was the connection to
the proxy server that failed) in the GError message when
g_socket_client_connect* fail.

This adds an extension point for TLS connections to gio, with a
gnutls-based implementation in glib-networking.
Full TLS support is still a work in progress; the current API is
missing some features, and parts of it may still be changed before
2.28.

GProxyConnection is a class that was added for proxy support;
g_socket_client_connect() returns a GSocketConnection, but in some
cases (eg, encrypted SOCKS), GProxy might return a GIOStream that is
not a GSocketConnection. In that case, GSocketClient would wrap the
stream up in a GProxyConnection, which is a subclass of
GSocketConnection but uses the input/output streams of the wrapped
connection.
GTlsConnection is not a GSocketConnection, so it has the same problem,
so it will need the same treatment. Rename the class to
GTcpWrapperStream, and make it public, so people can extract the base
stream from it when necessary.
(This is not ideal and GSocketClient will need to be revisited as an
API at some point...)

This allow application to take control over certain proxy protocol
handling. When a proxy protocol must be used and is found in the
application proxies, GSocketClient will simply TCP connect to the proxy
server and return the connection.

Using this rather than g_socket_client_connect() or
g_socket_client_connect_to_host() allows #GSocketClient to
determine when to use application-specific proxy protocols.

This functionnallity can be disabled using property enable-proxy. It
enumerates addresses using GSocketConnectable::proxy_enumerate() instead of
enumerate(). When the returned address is of type GProxyAddress (a type
based on GInetSocketAddress), it gets the proxy protocol handler using
g_proxy_get_default_for_protocol() and call connect() on it.

g_socket_client_connect_async() was always leaking its GCancellable,
and would also leak any GSocket that eventually failed to connect
after returning G_IO_ERROR_PENDING.
GSocket has a timeout flag now, but when using GSocketClient there was
no way to set the timeout until after connecting (or failing). Fix
that by adding a timeout property to GSocketClient.
GFile allows for the possibility that external implementations may not
support thread-default contexts yet, via
g_file_supports_thread_contexts(). GVolumeMonitor is not yet
thread-default-context aware.
Add a test program to verify that basic gio async ops work correctly
in non-default contexts.

Currently, to implement cancellability correctly, all synchronous
calls to GSocket must be preceded by a g_socket_condition_wait() call,
(even though GSocket does this internally as well) and all
asynchronous calls must do occasional manual
g_cancellable_is_cancelled() checks. Since it's trivial to do these
checks inside GSocket instead, and we don't particularly want to
encourage people to use the APIs non-cancellably, move the
cancellation support into GSocket and simplify the existing callers.

The whole protocol name thing is pretty weird. The getprotobyname functions
seem to only specify one mapping for name <-> ids, so all families/types
must use the same values. Plus the values used for the protocols are
standardized by IANA, so are always the same.
So, we drop using names for protocols, intead introducing an enum with
a few commonly availible and used protocols.
