05909d1cfa daemon: add a ClientCount dbus property 
Introduce a new "ClientCount" dbus property that can be queried and
also watched to see if gamemode is currently active (or not).

6d921617f9 daemon: make context_num_clients a public method 
So it can be used from outside daemon/gamemode.c, to e.g. implement
an ClientCount property.

d12ab6830f No old-style function definitions. 
Specify void as argument type for functions that don't take args.

9ade4481c3 Change AMD overclocking to simply be setting the power_dpm_force_performance_level file for now 
This covers the MVP for now, and simply allows pinning the power level to "high"

	Full overclocking set up is somewhat more complicated, and it'll be better to implement that at the same time as the same for Nvidia, where we're currently only really setting the top end power level

1430c0b831 Implement supervisor features using new config variables

	require_supervisor can also be used to allow a supervisor to take direct control of gamemode on the system (perhaps a GUI, or game launcher)

worried users show up.

fd4166279b gamemode: Convert game_mode_context_has_client() to return the client 
Returning a bool is not useful if we want to create some log information
from this. It now returns NULL or a client pointer which is compatible
with all of the current users.

When dereferencing the returned pointer, a read lock must be acquired
around using the returned result as the client may be deallocated from
heap otherwise.

8214f93630 gamemode: Optimize detection of dupe registers 
GameMode can do a pretty expensive lookup function now for the exe.
Let's spare some CPU cycles by detecting a duplicate PID early. Nothing

2a0c6e7098 gamemode: Never add NULL to the client list 
When running wine games, there's good chance the executable is already
gone when GameMode decided to add it to the list. Let's silently bail
out here. It probably grabs a non-matching PID anyway in this moment.
