a15abf82dd dix: always allocate and set the grab's sync.event
Allocate the memory at device creation time and always store the event, even
if we're not frozen. This way we know which event triggered the grab.
Since the event was never freed anyway except on device shutdown, this
doesn't really change things much.

47734b2ba2 dix: move delivery stop condition out of event mask
Previously, this was only called if there was a mask match, so even if we
had a no-propagate flag set or a stopAt window specified, if no mask
triggered on the window we would recurse up to the root window and
eventually deliver.
Move this, so that the stopAt and do-not-propagate mask is honoured.

86c3137c81 Xi: split updating button count and state into helper functions
Functional change: for a button mapped to 0, the motionHintWindow is not
updated to the NullWindow anymore. Before it got updated unconditionally to
the button mapping. I have no idea what the practical effect of this is, but
I guess it's closer to the correct behaviour: pressing a button that's
logically disabled now does not disrupt the motion hint delivery.

41dd7cf673 _XkbFilterDeviceBtn: move variable declarations to match usage scope
The main body of this function is an if { } else if { } pair of blocks.
Previously there was int button at the top level scope which is used
only in the first block, and a redeclaration of int button inside the
second block.   Since there's no overlap in the code paths for the
two uses of button, move the one from the outer block into the first
block to help the programmer more quickly determine they are unrelated
usages, and to silence the gcc warning of:

xkbActions.c: In function '_XkbFilterDeviceBtn':
xkbActions.c:999:6: warning: declaration of 'button' shadows a previous local
xkbActions.c:955:6: warning: shadowed declaration is here

d8eb9b5faa XkbFindSrvLedInfo: remove extraneous name-clashing sli variable
Variable is already defined outside the outer if statement, and
there's no need to redefine inside the if statement.

No point in setting sli before if (dev->kbdfeed->xkb_sli==NULL)
check - if check is true, we immediately set it, if check is false,
we immediately return without further reference or use of it.

The one thing we do with it inside the inner if statement is store
an allocation in it for a brief moment before writing to the final
destination, which is immediately returned to the caller.

In short, there's no benefit to the variable at all in this block,
it just gives the optimizer more code to figure out how to omit.

50b1097643 Constify the reason string throughout the authorization check framework
Almost all of the places the string is assigned point to a literal
string constant, so use const char * for those, and const char **
for function calls that return it via an argument.   Fortunately
the top level function, ClientAuthorized, which returns the string
as its return value is called from only one place, ProcEstablishConnection.

ProcEstablishConnection stores either that return value or a string literal
in char *reason.  It only uses reason as an argument to SendConnSetup.
SendConnSetup passes the reason argument to strlen & WriteToClient,
both of which already have const qualifiers on their args.
Thus added const to the reason variable in ProcEstablishConnection
and the reason argument to SendConnSetup.

9999819601 Constify string for authorization protocol names
gcc was warning from storing string constants in a char *name field:
auth.c:64:1: warning: initialization discards qualifiers from pointer target type
auth.c:72:1: warning: initialization discards qualifiers from pointer target type
auth.c:81:1: warning: initialization discards qualifiers from pointer target type

Making the field const requires changing AuthorizationFromID to take
a const char ** pointer for the name argument which it sets to point
to the matching name entry.

Changing that argument requires changing its sole caller in the security
extension to pass the address of a const char * variable to it, which it
can do, since the only thing it does with the returned name is to pass
it back to the RemoveAuthorization function that already expects a const
char *name.

01834e99e4 os/access.c: replace acmp & acopy macros with memcmp & memcpy calls
No need to cast to char * now that all supported platforms use C89-standard
void * argument types, so just drop the casts from acmp & acopy macros,
which clears the gcc warnings for places const pointers were cast non-const:

access.c: In function 'DefineSelf':
access.c:786:3: warning: cast discards qualifiers from pointer target type
access.c:795:6: warning: cast discards qualifiers from pointer target type
access.c: In function 'NewHost':
access.c:1293:9: warning: cast discards qualifiers from pointer target type
access.c:1298:6: warning: cast discards qualifiers from pointer target type
access.c:1309:5: warning: cast discards qualifiers from pointer target type

Without the casts, acmp & acopy are just a funny way to write memcmp
& memmove, so drop the macros and inline the calls, taking care to
swap the first two arguments to memmove since it had swapped them.

Since all the calls to memmove end up being to non-overlapping memory
(mostly copying from an existing pointer to a newly allocated one),
replace those with memcpy.

And finally, don't actually call memcpy to copy 0 bytes from one place
to another, since that's just a waste of a perfectly good function call.

2ddae8f0bd constify strings in resource name registry
LookupResourceName already returned a const char *, so just needed
to change the variable we're storing the list in to be a const char **
and then add const to the name argument to RegisterResourceName
(which just stores name in the array) and CreateNewResourceType
(which just passes name to RegisterResourceName).

Clears a bunch of gcc warnings of the form:
registry.c:319:5: warning: passing argument 2 of 'RegisterResourceName' discards qualifiers from pointer target type
registry.c:200:1: note: expected 'char *' but argument is of type 'const char *'

and from all the extensions:
damageext.c: In function 'DamageExtensionInit':
damageext.c:490:5: warning: passing argument 2 of 'CreateNewResourceType' discards qualifiers from pointer target type
