649293f6b6 xkb: always fill the symsPerKey array, regardless of client flags (#30527)
Even if a client does not modify the symbols, symsPerKey and mapWidths must
be filled from the current configuration. Both arrays are then passed into
other functions (pending the right flag), thus they must contain valid
values regardless of the XkbKeySymsMask flag in req->present.

9ac8e206ff xkb: use GetMaster instead of dev->u.master.
Devices that are both pointers and keyboards are not affected by keyboard
changes as their master device is a master pointer, not a master keyboard.
Use GetMaster() instead to ensure devices that are attached to the paired
master pointer device will still be update.

This avoids NULL from being passed to memcpy() later in the code. While
that wasn't an issue before - that value being NULL implied 'size == 0'
so memcpy() wouldn't try to dereference it - it made the code harder
to read and also confused clang.

This request is used to get the current keyboard group and is called from

b12d302df8 Input: rename DeviceIntRec->isMaster to ->type.
isMaster is not enough as long as we differ between master pointers and
keyboard. With flexible device classes, the usual checks for whether a
master device is a pointer (currently check for ->button, ->valuators or
->key) do not work as an SD may post an event through a master and mess this
check up.

Example, a device with valuators but no buttons would remove the button
class from the VCP and thus result in the
IsPointerDevice(inputInfo.pointer) == FALSE.

This will become worse in the future when new device classes are introduced
that aren't provided in the current system (e.g. a switch class).

This patch replaces isMaster with "type", one of SLAVE, MASTER_POINTER and
MASTER_KEYBOARD. All checks for dev->isMaster are replaced with an
IsMaster(dev).

When ProcXkbSetNamedIndicator is called on a core device, and we
walk the slaves to set the LED's on each of them, ignore any slaves
that do not have either a KbdFeedbackCtrl or LedCtrl structure.

(This is much more critical in xserver-1.5-branch, where we walk
 *all* devices, not just the slaves of the specified master, and
 thus return failure when setting an LED on the Core Keyboard and
 hit a xf86-input-mouse device with no LED's to set.)

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.

"The consumer was in past versions of the headers now located

all the event definitions were only available if NEED_EVENTS were
defined, and all the reply definitions required NEED_REPLIES.

Looks like Xproto.h dropped them by X11R6.3, which didn't have

49f77fff14 Rework symbol visibility for easier maintenance
Save in a few special cases, _X_EXPORT should not be used in C source
files. Instead, it should be used in headers, and the proper C source
include that header. Some special cases are symbols that need to be
shared between modules, but not expected to be used by external drivers,
and symbols that are accessible via LoaderSymbol/dlopen.

  This patch also adds conditionally some new sdk header files, depending
on extensions enabled. These files were added to match pattern for
other extensions/modules, that is, have the headers "deciding" symbol
visibility in the sdk. These headers are:
o Xext/panoramiXsrv.h, Xext/panoramiX.h
o fbpict.h (unconditionally)
o vidmodeproc.h
o mioverlay.h (unconditionally, used only by xaa)
o xfixes.h (unconditionally, symbols required by dri2)

  LoaderSymbol and similar functions now don't have different prototypes,
in loaderProcs.h and xf86Module.h, so that both headers can be included,
without the need of defining IN_LOADER.

  xf86NewInputDevice() device prototype readded to xf86Xinput.h, but
not exported (and with a comment about it).

d6cbd4511e Export symbols defined in the sdk.
This is the biggest "visibility" patch. Instead of doing a "export"
symbol on demand, export everything in the sdk, so that if some module
fails due to an unresolved symbol, it is because it is using a symbol
not in the sdk.

  Most exported symbols shouldn't really be made visible, neither
advertised in the sdk, as they are only used by a single shared object.
