Yuri Kunde Schlesner 7ada357b2d Memmap: Re-organize memory function in two files 
memory.cpp/h contains definitions related to acessing memory and
configuring the address space
mem_map.cpp/h contains higher-level definitions related to configuring
the address space accoording to the kernel and allocating memory.

Subv 000876858d Core/Memory: Give every emulated thread it's own TLS area. 
The TLS area for thread T with id Ti is located at TLS_AREA_VADDR + (Ti - 1) * 0x200.
This allows some games like Mario Kart 7 to continue further.

Yuri Kunde Schlesner 774eea8374 Kernel: Zero-fill shared memory blocks when mapping 
This works around crashes related to GSP/HID/etc. shared memory blocks
having garbage values. The proper fix requires proper management of
mapped memory blocks in the process.

Yuri Kunde Schlesner b700b55696 Common: Remove the BIT macro 
When the macro was introduced in 326ec51261
it wasn't noticed that it conflicted in name with a heavily used macro
inside of dyncom. This causes some compiler warnings. Since it's only
lightly used, it was opted to simply remove the new macro.

Subv 8e2b248e05 Build: Fixed some warnings 11 years ago
archshift ef24e72b26 Asserts: break/crash program, fit to style guide; log.h->assert.h 
Involves making asserts use printf instead of the log functions (log functions are asynchronous and, as such, the log won't be printed in time)
As such, the log type argument was removed (printf obviously can't use it, and it's made obsolete by the file and line printing)

Also removed some GEKKO cruft.

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 88a4a808c6 Kernel: Stop creating useless Handles during object creation 
They're finally unnecessary, and will stop cluttering the application's
handle table.

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.)
