cursor: Fix heap overflows when parsing malicious files.

It is possible to trigger heap overflows due to an integer overflow
while parsing images.

The integer overflow occurs because the chosen limit 0x10000 for
dimensions is too large for 32 bit systems, because each pixel takes
4 bytes. Properly chosen values allow an overflow which in turn will
lead to less allocated memory than needed for subsequent reads.

protocol: Suggest get_registry not be called frequently

I've heard some complaints that wl_display.get_registry "leaks"
server memory because wl_registry has no destructor.  While this isn't
strictly true - all those resources are freed when the client
disconnects - it's a bit of a gotcha for neophytes.

Since wl_registry's version is not requested in any way through
wl_display.get_registry, we can't add a destructor request without
breaking ABI.  So let's be a little more clear about the result
of getting too many wl_registry objects.

wayland-server: Add API to control globals visibility

Add a new API to let compositor decide whether or not a wl_global
should be advertised to the clients via wl_registry_bind() or
display_get_registry()

By using its own filter, the compositor can decide which wl_global would
be listed to clients.

Compositors can use this mechanism to hide their own private interfaces
that regular clients should not use.

- Hiding interfaces that expose compositor implementation details
  makes it harder for clients to identify the compositor. Therefore
  clients are a little less likely to develop compositor-specific
  workarounds instead of reporting problems upstream.

- Hiding can be used to diminish the problems from missing namespacing:
  if two compositors happen to use the same named global with
  different interfaces for their special-purpose clients, the client
  expecting the different interface would probably never see it
  advertised.

tests: add scanner tests

Add tests that ensure that wayland-scanner output for a given input does
not change unexpectedly. This makes it very easy to review
wayland-scanner patches.

Before, when patches were proposed for wayland-scanner, I had to
build wayland without the patches, save the generated files into a
temporary directory, apply the patches, build again, and diff the old
vs. new generated file.

No more. Now whenever someone makes intentional changes to
wayland-scanner's output, he will also have to patch the example output
files to match. That means that reviewers see the diff of the generated
files straight from the patch itself. Verifying the diff is true is as
easy as 'make check'.

The tests use separate example XML files instead of wayland.xml
directly, so that wayland.xml can be updated without fixing scanner
tests, avoiding the churn.

example.xml starts as a copy of wayland.xml. If wayland.xml starts using
new wayland-scanner features, they should be copied into example.xml
again to be covered by the tests.

This patch relies on the previous patch to actually add all the data
files for input and reference output.

The scanner output is fed through sed to remove parts that are allowed

wayland-client: Require base 10 for WAYLAND_SOCKET, explicitly

The third arg to strtol() specifies the base to assume for the number.
When 0 is passed, as is currently done in wayland-client.c, hexadecimal
and octal numbers are permitted and automatically detected and
converted.

I can find no indication that we would ever expect use of hexadecimal or
octal for socket fd's.  So be explicit about what base we're assuming
here and avoid any potential surprises.

Although wl_fixed_t can be thought of as an opaque struct, it is a typedef. As

leaves the typedef documentation blank in the documentation for wayland-util,
and does not provide a link to the documentation for wl_fixed_t. Hence, this
