* xdg_surface.c (AckConfigure): Improve debug code.
(Commit): Clear that flag.
(NoteBounds): If that flag is set, return.
(HandleFreeze): Assume a configure event will arrive after a
sync request; set flags accordingly.
(XLGetXdgSurface): Add HandleFreeze.
(XLXdgRoleSendConfigure): Clear some flags and add new state
flag `StateWaitingForAckCommit'. Set it. It means that no
commit has yet happened after ack_configure.
(XLXdgRoleNoteRejectedConfigure): New function. Clear flags if
the configure event following _NET_WM_SYNC_REQUEST was rejected.
* xdg_toplevel.c (struct _XdgToplevel): New state flags
StatePendingResize, StateConfigureSize,
StatePendingConfigureStates. New field `configuration_timer'.
(batch_state_changes): New flag.
(DestroyBacking): Clear configuration timer.
(NoteConfigureTime): New function; apply queued state changes.
(HandleWmStateChange, HandleConfigureEvent): By default, queue
state changes and configure events so they can be applied in one
go.
(Unmap): Clear delayed configuration timer.
(Commit, CommitInsideFrame, PostResize): Improve movement delta
adjustment for min_width and min_height, and queue pending
motion for after ack_configure.
(XLInitXdgToplevels): Set `batch_state_changes' depending on the
DIRECT_STATE_CHANGES' environment variable.
* 12to11.c (XLMain): Initialize primary selections. Transfer
between X and Wayland programs is still incomplete.

allocation failures.
* mime1.awk: Update generated code for changes in target entry
structures.
* seat.c (SetFocusSurface): Handle focus change for primary
selections as well.
(FindSurfaceUnder): Cut off fractional portion instead of
rounding the given coordinates, so the correct surface is found
when the cursor is moved just inside the rightmost pixel.
* surface.c (XLSurfaceRunFrameCallbacks): Handle timestamp
overflow.
* xdata.c (struct _TargetMapping): Rename atom to atom_flag, and
use it to store flags.
(MappingAtom, MappingFlag, MappingIsNextDuplicate, MappingSetFlag)
(MappingUnsetFlag, MappingIs): New macros.
(struct _TargetMappingTable): New structure.
(Duplicate): New definition.
(direct_transfer): Update duplicate types.

table to look up targets instead.
(CheckDuplicate): New function.
(SendOffers): Call CheckDuplicates.
(XLInitXData): Set up duplicate relationship between UTF8_STRING
and is conversion entry, and the targets mapping table.
