[ANNOUNCE] libei 1.0.0

[Peter Hutterer]

libei 1.0.0 is now available.


libei is a library to send Emulated Input (EI) to a matching Emulated Input
Server (EIS) which can receive those events with libeis, also part of this
project.

libei uses GitLab releases, for tarballs please see:
https://gitlab.freedesktop.org/libinput/libei/-/releases/1.0.0

# Changes:

Note that there is one minor protocol change (`ei_connection.sync`) and
one ABI (not API) change in libeis since the RC2 despite previous
statements that the protocol and API are stable. In both cases it was
better to do it now while every user of libei(s) is still in draft than
having to special-case those instances for the next 10 years.
An rebuild will take care of of the ABI change, making sure libei and
libeis are both on 1.0.0 will take care of the protocol change.

Notable changes since RC2:

- meson requirements dropped back to 0.56 to allow for building on older distros
- Protocol
  - ei_connection.sync now takes a version argument to allow for
    future updates of the ei_callback interface. This is a protocol
    change.
  - the ei-scanner now exposes interface_arg + interface_arg_for
    and version_arg + version_arg_for to allow for better handling
    of arguments that refer to interfaces or versions, respectively
- Library:
  - The enum eis_event_type was synced with libei so identical events
    (e.g. EI_EVENT_FRAME and EIS_EVENT_FRAME) have the same enum
    value in both libraries. This fixes commit e6954b76d. This is an ABI
    break, a rebuild will take care of it.
  - sending an ei_device_scroll_discrete event with value 1 now logs a
    bug. This typically indicates a bug in the caller and the value
    should be a fraction or multiple of 120 instead.
  - a few missing functions are now public: eis_region_contains(),
    eis_region_get_physical_scale(), eis_device_get_context(),
    eis_seat_get_context(), eis_device_get_width() and
    eis_device_get_height()
  - libeis *for now* sends all negotiated interface versions back to the
    client during the initial handshake. This isn't required by the
    protocol but it ensures those parts of any new client are working
    correctly.
