In ProcXkbGetKbdByName, mrep.firstVModMapKey, .nVModMapKeys and
.totalVModMapKeys were not initialized, contained random values and caused
accesses to unallocated and later modified memory, causing
XkbSizeVirtualModMap and XkbWriteVirtualModMap to see different number of
nonzero values, resulting in writes past the end of an array in XkbSendMap.
This patch initializes those values sensibly and reverts commits 5c0a2088 and
6dd4fc46, which have been plain non-sense.

Reproducible:
Configure a server that uses the keyboard driver with an invalid ruleset,
e.g. (Option "XkbRules" "foobar"). Ensure that Option "AllowEmptyInput" is
"off" in the ServerFlags or ServerLayout section. Start the server.
After failing to init the keymap, the server will try to clean up after the
device, double-freeing some xkb structs that have not been reset properly.

I really don't know what the purpose of this variable is or was, aside from
potentially clobbering up our key state since there's a path where it may be
used uninitialised.
Also, this means that xkbi->prev_state is now accessible from the DIX with
meaningful data.

We only have one root window and writing the rules used to the same property
for each device is quite pointless if you don't have the same RMLVO on all
devices. So let's be sensible and write the same property to the device too,
so at least we know which device got loaded with which RMLVO.
XkbGetRulesDftls may get a copy of what will later be freed when passed into
XkbSetRulesDftls.
On the second run of XkbGet/SetRulesDflts:
XkbGetRulesDflts(rmlvo)
rmlvo->rules = current-rules
XkbSetRulesDflts(rmlvo)
free(current-rules)
current-rules = strdup(rmlvo->rules)
Leaving us with garbage in current-rules.
This patch requires callers of XkbGetRulesDflts to free the associated memory.

Don't pass xEvent* and count through to processing, pass a single
InternalEvent.
Custom handlers are disabled for the time being. And for extra fun,
XKB's pointer motion emulation is disabled. But stick an error in there so
that we get reminded should we forget about it.

EnqueueEvent is a somewhat half-baked solution, we immediately drop back into

Don't let the dcce be random data.
Before dropping down into the DIX, convert back into XI events. This is a
temporary solution only, until the DIX is capable of handling InternalEvents
anyway.

Instead of always keeping two copies of the keymap, only generate the
core keymap from the XKB keymap when we really need to, and use the XKB
keymap as the canonical keymap.

Keyboard map notifications are always generated from within XKB code,
which also takes care of copying the keysyms, etc. If you need to
mangle the keymap yourself, generate a new core keymap/modmap, and pass
it to XkbApplyMappingChange.
SendMappingNotify is renamed to SendPointerMappingNotify (and ditto its
Device variants), which still only _sends_ the notifications, as opposed
to also doing the copying a la XkbApplyMappingChange.
Also have the modmap change code traverse the device hierachy, rather
than just going off the core keyboard.
