The public documentation included descriptions of wl_log_stderr_handler,
wl_log_func_t wl_log_handler, wl_log and wl_abort. These are not accessible
via the public API.
Move the doxygen \endcond command to wrap these definitions, removing them
from publication.

Move the wl_interface_equal prototype to the top of wayland-private, where
it is not buried in the middle of map, connection and closure functions.
Move the implementation out of connection and into util. This is a utility
function, not specific to connections, and has call sites within connection,
wayland-client and wayland-server.

On many places in the code we use wl_log + abort or wl_log + assert(0).
Replace these with one call to wl_abort, so that we don't mix abort(),
assert(0) and we'll save few lines

I got a little over-eager with my sanity checks and didn't realize that the
client uses wl_map_insert_at to mark objects as zombies when they come from
the server-side.

In order to use the second-lowest bit of each pointer in wl_map for the
WL_MAP_ENTRY_LEGACY flag, every pointer has to be a multiple of 4. This
was a good assumption, except with WL_ZOMBIE_OBJECT. This commit creates
an actual static variable to which WL_ZOMBIE_OBJECT now points. Since
things are only every compared to WL_ZOMBIE_OBJECT with "==" or "!=", the
only thing that matters is that it is unique.

The implementation in this commit allows for one bit worth of flags. If
more flags are desired at a future date, then the wl_map implementation
will have to change but the wl_map API will not.

The original wl_map implementation did no checking to ensures that ids fell
on the correct side of the WL_SERVER_ID_START line. This meant that a
client could send the server a server ID and it would happily try to use
it. Also, there was no distinction between server-side and client-side in
wl_map_remove. Because wl_map_remove added the entry to the free list
regardless of which side it came from, the following set of actions would
break the map:
1. Client creates a bunch of objects
2. Client deletes one or more of those objects
3. Client does something that causes the server to create an object
Because of the problem in wl_map_remove, the server would take an old
client-side id, apply the WL_SERVER_ID_START offset, and try to use it as a
server-side id regardless of whether or not it was valid.

If we cannot increase the array for new entries, we now return 0 instead
of accessing invalid memory.
krh: Edited to return 0 on failure instead. In the initialization path,
we call wl_map_insert_new() to insert NULL at index 0, which also returns
0 but not as an error. Since we do that up front, every other case of
returning 0 is an unambiguous error.

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.
Set the next and prev pointers of the removed list element to NULL. This
will catch programming errors that would use invalid list pointers,
double-remove for instance.
It also helps debugging, making it easy to see in gdb if an object is
not in a list.

We set aside a range of the object ID space for use by the server. This
allows the server to bind an object to an ID for a client and pass that
object to the client. The client can use the object immediately and the
server can emit events to the object immdiately.
