499af4c7bb Prevent platform profile error on unsupported systems
If a system does not support setting the platform profile (i.e., does
not have the file /sys/firmware/acpi/platform_profile), then everything
that interacts with it is skipped to prevent errors. This situation is
more common than I expected.[1]

d84c5ded1c Extract split lock mitigation into common file
This reduces duplication of the split lock mitigation path.
Additionally, it allows extending the functionality of procsysctl into
also getting the split lock mitigation state.

e75f2c3942 Support setting the platform profile
The platform profile lives in /sys/firmware/acpi/platform_profile. The
desiredprof and defaultprof options correspond to the values for the
platform profile set when gamescope begins and ends, respectively.

HACK: The platform profile may restrict what values the governor can
take, so we choose to set the governor before the platform profile in
order to store the correct default governor, and restore the platform
profile before the governor. This is done to maximize correctness after
restoration, but it can cause issues if the previous platform profile
restricts the governor.

TODO: Save all the state we care about before any of it is changed. In
thsi case, we should set (and restore) the platform profile before the
governor.

485a7f920a Move includes to the file that actually uses them
This was spotted thanks to clang-format reordering the includes.
Even with the new config, it will include the header file for the
current source file first. Nevertheless, it is best to always include
header files where they are needed.

126e67fb6b Run executables from PATH instead of /usr/bin
Not all distributions install non-system binaries into /usr/bin. For
example, NixOS installs packages to /nix/store using a unique hash
generated from the inputs used to build it:

/nix/store/jld7jh3ilvbg91zvn1bdyawfc55b9jk8-polkit-0.118-bin/bin/pkexec

3fcff0d75f Align open_fdinfo_dir with pidfds_to_pids
The function `pidfds_to_pids` expected `-1` if `open_fdinfo_dir` failed but the latter returned `errno` which is hard to distinguish from a valid file handle.  Correct that by making `open_fdinfo_dir` a wrapper around `open`.

5398dd1d19 common: add pidfd related methods
Add functions to open pidfds, i.e. file descriptors representing
processes, for process ids and vice versa. Both functions work
an array of fds/pids, stop on error and return the number of
successfully handled items.

4b59818fd4 common: add autofree helper
Much like the auto-closing helper for file descriptors, add a new
auto-free helper that is meant to be used with dynamically allocated
memory, a la:
  autofree char *data = NULL;
  ...
  data = malloc(size);
When data goes out of scope, cleanup_free will be called with &data,
i.e. cleanup_free(&data), which in turn will call free(3) data. In
order to work with all types, e.g. 'char *' (resulting in char **
being passed to cleanup_free) or 'int *' (resulting in int ** being
passed to cleanup_free), cleanup_free is defined to work with void *,
hence the odd-looking cast: void *target = *(void **) ptr.
