4b341a8b33 clients: Fix build without Cairo/GLES2
If we're building with EGL support generally, but without Cairo/GLESv2,
building the clients fail, because window.c defines the EGL native
types, however platform.h also brings these in.

3b7c207d06 window: Check for NULL surface in keyboard_handle_enter
This can happen if you right-click in weston-terminal a few times very quickly.
The pointer_handle_enter callback already checks for NULL, so let's do that in
keyboard_handle_enter, too.

894b3ecc63 clients: Add XKB compose key support
This adds single-symbol compose support using libxkbcommon's compose
functionality.  E.g., assuming you have the right alt key defined as
your compose key, typing <RAlt>+i+' will produce í, and <RAlt>+y+= will
produce ¥.  This makes compose key work for weston-editor,
weston-terminal, weston-eventdemo, and any other clients that use
Weston's window.* routines for accepting and managing keyboard input.

Compose sequences are loaded from the system's standard tables.  As
well, libxkbcommon will transparently load custom sequences from the
user's ~/.XCompose file.

Note that due to limitations in toytoolkit's key handler interface, only
compose sequences resulting in single symbols are supported.  While
libxkbcommon supports multi-symbol compose strings, support for passing
text buffers to Weston clients is left as future work.

This largely obviates the need for the weston-simple-im input method
client, which had provided a very limited compose functionality that was
only available in clients implementing the zwp_input_method protocol,
and with no mechanism to load system or user-specified compose keys.

9c93179023 data-device: Implement DnD actions
The policy in weston in order to determine the chosen DnD action is
deliberately simple, and is probably the minimals that any compositor
should be doing here.

Besides honoring the set_actions requests on both wl_data_source and
wl_data_offer, weston now will emit the newly added "action" events
notifying both source and dest of the chosen action.

The "dnd" client has been updated too (although minimally), so it
notifies the compositor of a "move" action on both sides.

Changes since v8:
  - Add back wl_data_offer.source_actions emission, gone during last
    code shuffling. Fix nits found in review.

Changes since v7:
  - Fixes spotted during review. Add client-side version checks.
    Implement .action emission as specified in protocol patch v11.

Changes since v6:
  - Emit errors as defined in DnD actions patch v10.

Changes since v5:
  - Use enum types and values for not-a-bitfield stored values.
    handle errors when finding unexpected dnd_actions values.

Changes since v4:
  - Added compositor-side version checks. Spaces vs tabs fixes.
    Fixed resource versioning. Initialized new weston_data_source/offer
    fields.

Changes since v3:
  - Put data_source.action to use in the dnd client, now updates
    the dnd surface like data_source.target events do.

Changes since v2:
  - Split from DnD progress notification changes.

Changes since v1:
  - Updated to v2 of DnD actions protocol changes, implement
    wl_data_offer.source_actions.
  - Fixed coding style issues.

Weston now sends wl_data_source.dnd_drop_performed and .dnd_finished in
order to notify about the different phases of DnD.

wl_data_source.cancelled is also used as mentioned in the docs, being
emitted also on DnD when the operation is meant to fail (eg. source
and dest didn't agree on a mimetype).

The dnd demo is also fixed so the struct dnd_drag isn't leaked.

https://bugs.freedesktop.org/show_bug.cgi?id=91943
https://bugs.freedesktop.org/show_bug.cgi?id=91944

Changes since v6:

Changes since v5:
  - Dissociate source and offer after cancel. Updated to
    apply on top of c9f8f8a7f.

Changes since v4:
  - Make wl_data_offer.finish with the wrong state an error.

Changes since v3:
  - Fixed wl_data_source.dnd_finished vs cancelled emission on
    when interoperating with version < 3 drag destinations.

Changes since v2:
  - Handle wl_data_offer.finish. Fixed commit log inconsistencies.
    Added version checks. Spaces vs tabs fixes. Fixed resource
    versioning.

  - Updated to protocol v2.

da9d8fa3e4 clients: Simplify memory allocation with xzalloc()
It is redundant to check x*alloc's return value for null pointers, since
they are guaranteed to either return non-NULL or terminate the program.

In cases where we memset the malloc'd memory to 0, we can more
efficiently use the xzalloc() routine.  zalloc looks for opportunities
to return memory chunks that have already been zero'd out, so it can
provide better performance.

This patch addresses this warning, reported by Denis Denisov:

  [clients/window.c:1164] -> [clients/window.c:1166]: (warning) Possible
  null pointer dereference: surface - otherwise it is redundant to check
  it against null.

6c71aaeec5 Pass config file from compositor to everything
We have the Weston command line option '--no-config' which is meant to
prevent loading weston.ini at all. It works for Weston itself, but it
does not work for any clients that also want to read weston.ini.

To fix that, introduce a new environment variable WESTON_CONFIG_FILE.
Weston will set it to the absolute path of the config file it loads.
Clients will load the config file pointed to by WESTON_CONFIG_FILE. If
the environment variable is set but empty, no config file will be
loaded. If the variable is unset, things fall back to the default
"weston.ini".

Note, that Weston will only set WESTON_CONFIG_FILE, it never reads it.
The ability to specify a custom config file to load will be another patch.

All programs that loaded "weston.ini" are modified to honour
WESTON_CONFIG_FILE.

a519d06a53 window: use roundtrip instead of dispatch after get_registry
wl_display_dispatch() just dispatches events that are in
default and display queues and if there are no events,
then it will wait for them. But only dispatching
the events doesn't guarantee that we got all the global announcements,
we need to do sync too. Therefore use wl_display_roundtrip() instead
of wl_display_dispatch().
