GetZero
Always returns u32 0.
GetProcessesWithFlag4
Returns an array of pids of all processes that have mask 4 set in process flags.
StartProcess
Takes a pid. Process state must be 0 or 1. Then it uses svcStartProcess(process_handle, u8, u8, u32) with args coming from ldr:pm GetProgramInfo.
After that, it sets process state to 2.

FinalizeDeadProcess
Takes a pid as input. If the process with pid has the state "dead", it unregisters the pid in fsp:pr, sm:m, and ldr:pm.
Then it removes the process from PMs internal linked-list of active processes.
ClearProcessCrashedFlag
Takes a pid as input. Clears 0x10 from process flags.
NotifyBootFinished
Launches a process with hardcoded boot2 title-id.
GetCrashingProcessPid
Loops through the internal linked-list of processes, looks for mask 0x40 set in process flags. Returns pid of first such entry.
