This is needed for doxygen to generate output for macro definitions, such
as wl_container_of, that are contained by this file. Classes like
wl_list would be documented regardless.
This commit adds support for server-side languages bindings. This is done
in two ways:
1. Adding a wl_resource_set_dispatcher function that corresponds to
wl_resource_set_interface. The only difference between the two functions
is that the new version takes a dispatcher along with the implementation,
data, and destructor. This allows for runtime calling of native language
functions for callbacks instead of having to generate function pointers.
2. Adding versions of wl_resource_post_event and wl_resource_queue_event
that take an array of wl_argument instead of a variable argument list.
This allows for easier run-time argument conversion and removes the need
for libffi-based calling of variadic functions.

With the work to add wl_resource accessors and port weston to use them,
we're ready to make wl_resource and wl_object opaque structs. We keep
wl_buffer in the header for EGL stacks to use, but don't expose it by
default. In time we'll remove it completely, but for now it provides a
transition paths for code that still uses wl_buffer.

The _* namespace and identifiers with double underscore are reserved
by the C standard. That makes __wl_container_of is double plus bad,
so lets just call it wl_container_of.
Exporting unprefixed symbols is a pretty bad idea so don't do that.
Instea of redefining it WL_ARRAY_LENGTH, we just move the define to
our private header. The scanner generates code that uses ARRAY_LENGTH,
but we can just make it count the number elements and emit an integer
constant instead.
We might have to perform memory allocations in wl_array_copy(), so catch
out-of-memory errors in wl_array_add() and return -1 before changing any
state.

The core libwayland libraries should not handle logging, only passing
the error messages to subscribed functions.
An application linked to libwayland-server or libwayland-client
will be able to set own functions (one per library) to handle error
messages.
Change in this series: make the wl_log return int, because
of compatibility with printf. It will return the number of bytes logged.
'fixed' is a signed decimal type which offers a sign bit, 23 bits of
integer precision, and 8 bits of decimal precision. This is exposed as
an opaque struct with conversion helpers to and from double and int on
the C API side.

We need to make sure the client doesn't reuse an object ID until the
server has seen the destroy request. When a client destroys an ID
the server will now respond with the display.delete_id event, which lets
the client block reuse until it receives the event.
