Simon Ser e035f2b9c4 Fix invalid uses of wl_array_for_each
[1] and [2] have introduced new wl_array usage in wlroots, but
contains a mistake: wl_array_for_each iterates over pointers to
the wl_array entries, not over entries themselves.

Fix all wl_array_for_each call sites. Name the variables "ptr"
to avoid confusion.

Justus Rossmeier b9e9e0e133 tablet_v2: Fix implicit grab end detection
Store the previously focused surface in `state->focused` as well as in
`state->original` when starting an implicit grab. That way at the end
of an implicit grab, the detection whether the grab started and ended
on the same surface works as intended, even if the original surface was
never left at all.

Tudor Brindus 7693fdb8a7 tablet: expose wlr_tablet_tool_v2_has_implicit_grab function
This is necessary so that sway can determine when to start emulating
pointer events -- it shouldn't start doing so during an implicit grab,
even if the pen is over a surface that doesn't bind tablet input.

Simon Ser 5cde35923c Simplify globals implementation by removing destructors
Some globals are static and it doesn't make sense to destroy them before
the wl_display. For instance, wl_compositor should be created before the
display is started and shouldn't be destroyed.

For these globals, we can simplify the code by removing the destructor
and stop keeping track of wl_resources (these will be destroyed with the
wl_display by libwayland).

Simon Ser ca45f4490c Remove all wayland-server.h includes
The documentation for wayland-server.h says:

> Use of this header file is discouraged. Prefer including
> wayland-server-core.h instead, which does not include the server protocol
> header and as such only defines the library PI, excluding the deprecated API
> below.

Replacing wayland-server.h with wayland-server-core.h allows us to drop the
WL_HIDE_DEPRECATED declaration.

Markus Ongyerth 09b2833dcd send proximity_out in proximity in for tablet_v2
When the proximity_in event is sent for tablet_v2 and there's already a
surface that currently has tablet (tool) focus, it should be told that
this is no longer the case, so we need to send the proximity_out event.

random human 8589ae19de Fix bugs listed by clang's static analyzer
A few pedantic changes and unused variables (1-4), and genuine bugs (5,
6).

The reports with the corresponding files and lines numbers are as
follows.

1. backend/libinput/tablet_pad.c@31,44,57
"Allocator sizeof operand mismatch"
"Result of 'calloc' is converted to a pointer of type 'unsigned int',
which is incompatible with sizeof operand type 'int'"

2. types/tablet_v2/wlr_tablet_v2_pad.c@371
"Allocator sizeof operand mismatch"
"Result of 'calloc' is converted to a pointer of type 'uint32_t', which
is incompatible with sizeof operand type 'int'"

3. types/wlr_cursor.c@335
"Dead initialization"
"Value stored to 'dx'/'dy' during its initialization is never read"

4. rootston/xdg_shell.c@510
"Dead initialization"
"Value stored to 'desktop' during its initialization is never read"

5. types/tablet_v2/wlr_tablet_v2_pad.c@475
"Dereference of null pointer"
"Access to field 'strips' results in a dereference of a null pointer
(loaded from field 'current_client')"

The boolean logic was incorrect (c.f. the check in the following
function).

6. examples/idle.c@163,174,182
"Uninitialized argument value"
"1st function call argument is an uninitialized value"

If close_timeout != 0, but simulate_activity_timeout >= close_timeout,
the program would segfault at pthread_cancel(t1).

Markus Ongyerth f64962ace8 tablet-v2 tool: Implement implicit grab
Implement the tablet-v2 tablet tool's implicit grab semantics for
buttons and tip.

This avoids losing focus (to other [sub]surfaces) when a button is held,
or the tip is down.
This should help when the device is used close to a surface's border and
would otherwise have to be very precise.

Markus Ongyerth 9a6f77fc2c tablet-v2: fix merge commits and test again
There were a few issues after rebase, that the merge algorithm didn't
throw at my face:

wlr_output did a check on the actual role, not a string anymore, so that
had to go to allow tablet-v2 to set cursor surfaces.
A few L_DEBUG/L_ERRORs were still around
There was a user-after-free in tablet-group free()ing, probably after
insufficient testing from a previous feedback pass

Markus Ongyerth d9e978e1b3 rename wlr_tablet_tool to wlr_tablet
The previous naming was based on the input-device capability names from
libinput.
With code that uses the libinput_tablet_tool and mapping into tablet-v2,
this is confusing, so the name is changed to follow the names used in
the protocol.
