gdkchan c0dc0f2c3f Better process implementation (#491)
* Initial implementation of KProcess

* Some improvements to the memory manager, implement back guest stack trace printing

* Better GetInfo implementation, improve checking in some places with information from process capabilities

* Allow the cpu to read/write from the correct memory locations for accesses crossing a page boundary

* Change long -> ulong for address/size on memory related methods to avoid unnecessary casts

* Attempt at implementing ldr:ro with new KProcess

* Allow BSS with size 0 on ldr:ro

* Add checking for memory block slab heap usage, return errors if full, exit gracefully

* Use KMemoryBlockSize const from KMemoryManager

* Allow all methods to read from non-contiguous locations

* Fix for TransactParcelAuto

* Address PR feedback, additionally fix some small issues related to the KIP loader and implement SVCs GetProcessId, GetProcessList, GetSystemInfo, CreatePort and ManageNamedPort

* Fix wrong check for source pages count from page list on MapPhysicalMemory

* Fix some issues with UnloadNro on ldr:ro
