Enrico Weigelt, metux IT consult ead7cd4369 dix: use calloc() in _dixAllocateScreenObjectWithPrivates()
We're clearing the whole object size anyways, so we can directly
use calloc() instead of malloc() plus memset().

Enrico Weigelt, metux IT consult 9903f2bf40 damage: fix resource access flag on destroy
When destroying a resource, the lookup needs to be done with
DixDestroyAccess (instead of DixWriteAccess) flag - otherwise
xace hooks can't properly differenciate what's happening.

Enrico Weigelt, metux IT consult 86cf2c5ce3 Xi: use fixed define for extenion base opcode
Several places outside Xi (eg. dix, security hooks, ...) need to know the
actual XI base opcode. This formerly had been done by a global variable,
which is filled on XI init. This has some drawbacks, eg. requires that
XI really is initialized before anybody else attempting to access this
variable - changes in extension init order could be dangerous.

Since extension opcodes are now (compile-time) fixed for all known
extensions (including XI), this isn't needed anymore. We can really
rely on the XI extension always having the same opcode base. So we
can drop that variable entirely and use the corresponding define instead.

Enrico Weigelt, metux IT consult c6eaca88cd dix: reserve fixed extension opcodes for known extensions
Assign fixed opcodes for known (in-tree) extensions and add
defines for them. Other places (eg. security extensions) that
need to know those opcodes now can directly use those defines
not having to look them up at runtime.

Enrico Weigelt, metux IT consult 4560d9a3fe dix: add support for reserved extension slots
In order to allow extensions being registered at fixed opcodes,
there need to be a reserved slot range. Thus `NumExtensions` needs
to start out with the upper ceiling of the reserved slot space.
Thus it cannot tell whether the array already had been allocated,
and some slots now may be NULL, so we need some extra checks.
