This will be useful for keying specific executables to steamids.
This is sadly required because a bunch of games end up naming themselves
"game.exe" so we can't safely enable thunks for all things shipping a
generic name.
This is a relatively invasive change since multiple things needed to
happen at once.
* Socket based logging is removed
* Logging has been replaced to only support stdout, stderr, and server
* Server is now default and replaces what FEXLogServer did
* Server logging now uses a pipe instead of a socket
* Can be faster than stderr and stdout since the application doesn't
need to wait on terminal output
* FEXMountDaemon has been removed
* Functionality has been merged in to FEXServer
* FEXServer is always executed on FEX initialization time
* Similar in behaviour to Wine's wineserver
* Can explicitly start this before using FEX for logging purposes
* Stays around until all instances of FEX exit
* Will stick around for a short amount of time in case of spurious
execution
* FEXServer will soon be extended to do more than logging and squashfs
mounting
* FEX rootfs scripts will need to be updated to support this path
* Just means rbinding the /tmp folder and forcing a FEXServer instance
to be alive
* Pressure-vessel works fine in this case since FEXServer will already
be running
* It already rbinds the host /tmp folder which is why this works
This solves a problem where sometimes FEX would spin up a new process
while FEXMountDaemon was in the process of shutting down. Breaking
things on both sides.
Now the race conditions are squashed that I could see.
Also fixes one race where FEX is starting up and FEXMountDaemon is
spinning up. This case is where FEX managed to pull the lock file just
before it got deleted. Then sent the FEXMountDaemon a request to be
observed. With DGRAM sockets we would fire and forget. Use a STREAM with
a ack result so we know we can return.
This isn't quite a 100% clean sweep of IWYU.
There are some false positives where clang fails.
Additionally there are still a few missed in the frontend side of things
that I didn't get to
Puts the visibility of the main layer, application layers, and
environment in to FEXCore instead of FEX.
These layers aren't specific to FEX/FEXLoader and should live in
FEXCore.
Only the EmptyMapper remains in FEX, which should eventually move over
to FEXConfig since that is the only user.
