do not check if a layer surface has monitor on commit

We do not allow creating them w/o monitor and they are destroyed when
destroying their monitor

send wl_surface.enter before initial commit

It's not necessary but it'll help clients to render a perfect first frame

destroy the layer-suface's scene tree for popups

use wlr_box_equal() instead of memcmp

simplify settings popups scene tree parent

simplify check for wlr_layer_surface.output

use sizeof(*pointer) instead of sizeof(struct)

add new 'unreleased' section

make sure to unlink Monitor.request_state listener

Change github links to codeberg links in README.md

include CHANGELOG.md in the tarball

Fixes: 24576f1fdf56bc8879203bb2d7e7cd116d4bba42

bump version to 0.5

add CHANGELOG.md

Merge branch 'wlroots-next'

try to apply gamma LUT in updatemons

this in the case the output was re-enabled

ignore wl_surface.commit for xwayland clients

This is no longer needed

Do not send repeated xdg_toplevel.configure_bounds

Fixes: 32e66f45827cc8016ca2cef65ba61840f43fcc85

createkeyboard: do not segfault if xkb_keymap_new_from_names returns NULL

Passing NULL to wlr_keyboard_set_keymap results in a segfault.
Example:

  Thread 1 "dwl" received signal SIGSEGV, Segmentation fault.
