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.

Previously, it was looping through sizeof(ev->valuators.mask) * 8
valuators, where valuators.mask is defined as an array of
(MAX_VALUATORS + 7) / 8 entries. Since MAX_VALUATORS is defined as 36,
this made it actually loop through 40 entries. The last 4 bits in this
array should never be set, so we should never access memory outside the
bounds of the arrays defined to be exactly MAX_VALUATORS in length, but
we can make the static analyzer happier and not waste time checking bits
that should never be set.
Found by Oracle Parfait 13.3 static analyzer:

The XI2 protocol supports per-axis modes, but the server so far does
not. This change adds support in the server.
A complication is the fact that XI1 does not support per-axis modes.
The solution provided here is to set a per-device mode that defines the
mode of at least the first two valuators (X and Y). Note that initializing
the first two axes to a different mode than the device mode will fail.
For XI1 events, any axes following the first two that have the same mode
will be sent to clients, up to the first axis that has a different mode.
Thus, if a device has relative, then absolute, then relative mode axes,
only the first block of relative axes will be sent over XI1.
Since the XI2 protocol supports per-axis modes, all axes are sent to the
client.

Devices that send motion events with valuators other than x/y get core
