Adds a minimalistic API for managing the subscription object. The
subscribe functionality will be brought in once we re-organize a bit
weston-debug-stream and split it properly. It extends the logging
context with a linked list of potential subscription and adds a linked
list of subscriptions in the log scope.
This patch represents the start of a logging framework for weston. It's
being built around weston-debug, with the intent to superseded it, and
make weston-debug a client of the framework. Further more the logging
framework should replace current logging handler and allow other types
of streams to be used.
Currently present in libweston under weston-debug we have log scopes, debug
streams and a logging context.
With this patch, two (internal) objects are being added: the concept of
a subscriber and the concept of subscription. The subscription object
is a ephemeral object, implicitly managed which is created each time one
would want to a subscribe to a scope. The scope will maintain a list of
subscriptions and will continue to be explicitly managed.
The streams will use the subscriber object as a base class to extend
upon. By doing so it allows to customize the stream with specific
functions that manipulate the underlaying storage. The subscriber object
will require a subscribe function and specific stream functions and like
the scope, will be explicitly managed.

This fixes warnings for weston-debug, input, compositor, log and
linux-explicit-sync. Warnings range from swapping '[in]', '[out]' with
the function arguments to wrong parameter names.

This is no longer needed. Also assert if the context passed is NULL and
compositor log context is already set.

As we transition towards a more generic API for weston loggging
framework rename weston_debug_compositor to weston_log_context to show
the fact that this is not really debug but a logging context.

This patch allows initialization of weston-debug/log framework much earlier
than weston_compositor, which in turn will provide the option start
logging before weston_compositor has been created.

The main idea is to make libweston users use the form
#include <libweston/libweston.h>
instead of the plain
#include <compositor.h>
which is prone to name conflicts. This is reflected both in the installed
files, and the internal header search paths so that Weston would use the exact
same form as an external project using libweston would.
The public headers are moved under a new top-level directory include/ to make
them clearly stand out as special (public API).

weston_debug is both a libweston API for relaying debugging messages,
and the compositor-debug wayland protocol implementation for accessing those
debug messages from a Wayland client.
weston_debug_compositor_{create,destroy}() are private API, hence not
exported.
