New minor version.

Now at 1.4.0.

It seems mutter-48 needs the updated libei. Unfortunately fd.o is under maintenance now.

The package builds without issue with the current instructions.

I will hold off updating this package until the freedesktop site is back up.

freedesktop.org is back up.

libei 1.4 has a few new APIs:

ei_disconnect() is now public and thus can be invoked by the caller. Previously 
the only way to disconnect was to release the last ref to the ei context (which
would then ei_disconnect() internally). This made cleanup code more difficult
than it needed to be. Callers can now ei_disconnect() and unref when they're
finished with the cleanup.

libei now provides an ei_ping() call with a corresponding EI_EVENT_PONG event. 
Calling that function allows a caller to order events correctly, e.g. issuing a 
request followed by ei_ping() guarantees that any effects of the request will
have been processed by the time the EI_EVENT_PONG arrives (and thus any events
after that the event are caused by other reasons).

libeis now provides an eis_ping() call and EIS_EVENT_PONG event that works 
effectively just like the libei one.

This functionaliy has been part of the protocol already but was not previously 
exposed.

The documentation has been updated that the modifiers event 
(eis_device_keyboard_send_xkb_modifiers()) should be generated fro any state
change. This makes proper tracking of the XKB state in the client more reliable
(well, possible). Note that for proper tacking the client will require the use
of ei_ping() so it can associate any key events with the correct modifier state
at the time.

• test: keep the announced interface as local variable
• test: switch a bool([...]) to any()
• test: ignore a ConnectionResetError during our dispatch
• test: ignore a failure to send a pong
• test: fix a spuriously failing timeout
• tools/debug-events: add missing linebreaks to the modifier event
• ei: indentation fix
• proto: add two missing comments for consistency
• test: drop the use of attr
• test: rename a variable to shut up ruff with default args
• CI: force all auto features to enabled
• doc: unwinding state before stop_emulating is the caller's responsibility
• protocol: fix the description summary for the touch events
• Add the ei_touchscreen.cancel event and ei_touch_cancel()
• doc: fix some linewrapping issues
• tools/demo-server: note that aborting on unknown events is bad
• doc: specifically mention that unknown events must be unref'd
• ei: revamp the internal sync callback
• eis: revamp the internal sync callback
• ei: add ei_ping() and the matching EI_EVENT_PONG
• eis: add eis_ping() and the matching EIS_EVENT_PONG
