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.

The only remaining X-functions used in server are XNF*, the rest is converted to
plain alloc/calloc/realloc/free/strdup.
X* functions are still exported from server and x* macros are still defined in
header file, so both ABI and API are not affected by this change.
