Subv 3165466b66 Kernel/Thread: Allow specifying which process a thread belongs to when creating it. 
Don't automatically assume that Thread::Create will only be called when the parent process is currently scheduled. This assumption will be broken when applets or system modules are loaded.

Yuri Kunde Schlesner 64ecf81a3c Kernel: Move WaitObject to a separate file 
Now that HandleTable doesn't directly depend on WaitObject anymore, this
can be separated from the main kernel.h header.

Don't yield execution in SleepThread(0) if there are no available threads to run

Subv fc2266130b Kernel: Don't attempt to yield execution in SleepThread(0) if there are no available threads to run. 
With this we avoid an useless temporary deschedule of the current thread.

Subv cef5f45de2 Kernel: Use different thread statuses when a thread calls WaitSynchronization1 and WaitSynchronizationN with wait_all = true. 
This commit removes the overly general THREADSTATUS_WAIT_SYNCH and replaces it with two more granular statuses:

THREADSTATUS_WAIT_SYNCH_ANY when a thread waits on objects via WaitSynchronization1 or WaitSynchronizationN with wait_all = false.

THREADSTATUS_WAIT_SYNCH_ALL when a thread waits on objects via WaitSynchronizationN with wait_all = true.

Subv 17b29d8865 WaitSynch: Removed unused variables and reduced SharedPtr copies. 
Define a variable with the value of the sync timeout error code.

Use a boost::flat_map instead of an unordered_map to hold the equivalence of objects and wait indices in a WaitSynchN call.

Subv bdad00c73f Threading: Added some utility functions and const correctness. 9 years ago
Subv 8634b8cb83 Threading: Reworked the way our scheduler works. 
Threads will now be awakened when the objects they're waiting on are signaled, instead of repeating the WaitSynchronization call every now and then.

The scheduler is now called once after every SVC call, and once after a thread is awakened from sleep by its timeout callback.

This new implementation is based off reverse-engineering of the real kernel.

See https://gist.github.com/Subv/02f29bd9f1e5deb7aceea1e8f019c8f4 for a more detailed description of how the real kernel handles rescheduling.

Emmanuel Gil Peyrot ebdae19fd2 Remove empty newlines in #include blocks. 
This makes clang-format useful on those.

Also add a bunch of forgotten transitive includes, which otherwise
prevented compilation.

Subv d192fb066d Kernel/Threads: Dynamically allocate the TLS region for threads in the BASE region of the linear heap. 
Each thread gets a 0x200-byte area from the 0x1000-sized page, when all 8 thread slots in a single page are used up, the kernel allocates a new page to hold another 8 entries.

This is consistent with what the real kernel does.

the address space accoording to the kernel and allocating memory.

Kevin Hartman 5fcbfc06eb Scheduler refactor Pt. 1 
* Simplifies scheduling logic, specifically regarding thread status. It should be much clearer which statuses are valid
for a thread at any given point in the system.
* Removes dead code from thread.cpp.
* Moves the implementation of resetting a ThreadContext to the corresponding core's implementation.

Other changes:
* Fixed comments in arm interfaces.
* Updated comments in thread.cpp
* Removed confusing, useless, functions like MakeReady() and ChangeStatus() from thread.cpp.
* Removed stack_size from Thread. In the CTR kernel, the thread's stack would be allocated before thread creation.

Yuri Kunde Schlesner 52f58e64ef Kernel: Make WaitObjects share ownership of Threads waiting on them 
During normal operation, a thread waiting on an WaitObject and the
object hold mutual references to each other for the duration of the
wait.

If a process is forcefully terminated (The CTR kernel has a SVC to do
this, TerminateProcess, though no equivalent exists for threads.) its
threads would also be stopped and destroyed, leaving dangling pointers
in the WaitObjects.

The solution is to simply have the Thread remove itself from WaitObjects
when it is stopped. The vector of Threads in WaitObject has also been
changed to hold SharedPtrs, just in case. (Better to have a reference
cycle than a crash.)

Yuri Kunde Schlesner 7725256f64 Explicitly instantiate constructors/destructors for Kernel objects 
This should speed up compile times a bit, as well as enable more liberal
use of forward declarations. (Due to SharedPtr not trying to emit the
destructor anymore.)
