b5a019d575 build: simplify Meson subproject fallbacks
All of these projects use meson.override_dependency() so we can
stop referencing their internal variable name to grab the
depndencies we need.

72ee196efa backend/session: use DRM_PRIMARY_MINOR_NAME
Instead of hardcoding the string "card", use DRM_PRIMARY_MINOR_NAME.
Some systems may use another prefix, e.g. OpenBSD uses "drm" instead.

7f09085461 backend/session: Remove session_impl
libseat provides all session functionality, so there is no longer need
for a session backend abstraction. The libseat device ID, seat handle
and event loop handle are moved to the main wlr_session and wlr_device
structs.

e8d56ca415 backend/session: allow wlr_session_find_gpus to return an error
Sometimes wlr_session_find_gpus will encounter an error. This is
different from finding zero GPUs.

On error, wlr_session_find_gpus already returns -1. However, this is
casted to size_t, so callers uncorrectly assume this is a success.

Instead, make wlr_session_find_gpus return a ssize_t and allow callers
to handle the error accordingly.

fbf11a41e1 backend/session: wait for DRM device if none found
Wait for a DRM device if none is found in wlr_session_find_gpus. This
can happen if the compositor is loaded before the display kernel driver.

This supersedes the logind CanGraphical property.

To test, e.g. with i915 and sway:

    rmmod -f i915
    sway &
    modprobe i915

768fbaad54 backend/session: filter udev events by sysname
We're only interested in card devices. The loop over wlr_session.devices
would take care of ignoring non-card events, but a future patch will
listen to udev "add" events as well.

44a4792fd8 backend/session: operate on wlr_device
Instead of operating on FDs in {open,close}_device, operate on
wlr_devices. This avoids the device lookup in wlr_session and allows
callers to have access to wlr_device fields.

For now, we use it to remove wlr_session_signal_add and replace it with
a more idiomatic wlr_session.events.change field. In the future, other
events will be added.

fa05d3cde6 session: Don't refuse unprivileged creation of "direct" backend
When starting a compositor that's using the "direct" session backend,
wlroots needs to handle calls to `drmSetMaster()` and `drmDropMaster()`.
As both calls used to require `CAP_SYS_ADMIN`, wlroots thus simply
refused starting in case the process doesn't enjoy evelated privileges.

Permission rules have changed since linux.git commit 45bc3d26c95a (drm:
rework SET_MASTER and DROP_MASTER perm handling, 2020-03-19). As a
result, starting with Linux v5.8, both ioctls will now also succeed if
the process is currently or has been the DRM master. And as the first
process to open render nodes will become the DRM master automatically,
this effectively means that process elevation is not strictly required
in all setups anymore.

So let's drop the `geteuid() != 0` permission check to allow those new
rules to do their magic.

906c0766df Remove libcap support
This is simply a false sense of security, and is worse than just using
setuid. CAP_SYS_ADMIN is an extremely serious capability that is
effectively as powerful as root.

It also required users to be in the input group, which allows any
process to keylog the entire system.

30308e35fa build: Add 'auto' to logind-provider combo option
The logind provider defaulted to systemd and in order to use elogind,
-Dlogin-provider=elogind was required. This adds 'auto' as a choice
for the login-provider option and sets it as default. Using 'auto',
the build will check for systemd first and if it's not found, try
to find and use elogind automatically.

cff1c2f740 meson: Various improvements
Bumps minimum version to 0.51.0

- Remove all intermediate static libraries.
  They serve no purpose and are just add a bunch of boilerplate for
  managing dependencies and options. It's now managed as a list of
  files which are compiled into libwlroots directly.

- Use install_subdir instead of installing headers individually.
  I've changed my mind since I did that. Listing them out is annoying as
  hell, and it's easy to forget to do it.

- Add not_found_message for all of our optional dependencies that have a
  meson option. It gives some hints about what option to pass and what
  the optional dependency is for.

- Move all backend subdirectories into their own meson.build. This
keeps some of the backend-specific build logic (especially rdp and
session) more neatly separated off.

- Don't overlink example clients with code they're not using.
  This was done by merging the protocol dictionaries and setting some
  variables containing the code and client header file.
  Example clients now explicitly mention what extension protocols they
  want to link to.

- Split compositor example logic from client example logic.

- Minor formatting changes

fc6c0ca12e backend/session/freebsd: Fix the way to get TTY path
Previously, the path of TTY is generated using snprintf with %d format.
It works with TTY 1 to 10, but fails with TTY with greater number
because the number used in the name is in base 32 instead of base 10.
Since there is no standard function to convert a number to a string with
a custom base, this commit adds a function to do it.
