Michael Scire 5a7eecc3ad loader: provide default arguments (zero byte) to NSOs
Certain newer unity games (Terraria, Pokemon Mystery Dungeon) require
that the argument region be populated. Failure to do so results in
an integer underflow in argument count, and eventually an unmapped
read at 0x800000000. Providing this default fixes this.

Note that the behavior of official software is as yet unverified,
arguments-wise.

Markus Wick 7e94e544f4 core/loaders: Simplify PhysicalMemory usage.
It is currently a std::vector, however we might want to replace it with a more fancy allocator.
So we can't use the C++ iterators any more.

Fernando Sahmkow 9bede4eeed VM_Manager: Align allocated memory to 256bytes
This commit ensures that all backing memory allocated for the Guest CPU
is aligned to 256 bytes. This due to how gpu memory works and the heavy
constraints it has in the alignment of physical memory.

common/hex_util: Combine HexVectorToString() and HexArrayToString()
These can be generified together by using a concept type to designate

Lioncash 612e1388df core/core: Move process execution start to System's Load()
This gives us significantly more control over where in the
initialization process we start execution of the main process.

Previously we were running the main process before the CPU or GPU
threads were initialized (not good). This amends execution to start
after all of our threads are properly set up.

Lioncash c0a01f3adc kernel/codeset: Make CodeSet's memory data member a regular std::vector
The use of a shared_ptr is an implementation detail of the VMManager
itself when mapping memory. Because of that, we shouldn't require all
users of the CodeSet to have to allocate the shared_ptr ahead of time.
It's intended that CodeSet simply pass in the required direct data, and
that the memory manager takes care of it from that point on.

This means we just do the shared pointer allocation in a single place,
when loading modules, as opposed to in each loader.

Lioncash 1cf90f4570 file_sys/patch_manager: Deduplicate NSO header

Lioncash 90e27ea003 loader/nso: Fix definition of the NSO header struct

NSO file.

Lioncash 1b6bd9d6df kernel: Move CodeSet structure to its own source files
Given this is utilized by the loaders, this allows avoiding inclusion of
the kernel process definitions where avoidable.

This also keeps the loading format for all executable data separate from
the kernel objects.

Lioncash 1abed2f4c4 kernel/process: Make CodeSet a regular non-inherited object
These only exist to ferry data into a Process instance and end up going
out of scope quite early. Because of this, we can just make it a plain
struct for holding things and just std::move it into the relevant
function. There's no need to make this inherit from the kernel's Object
type.

Lioncash cf9d6c6f52 kernel/process: Make data member variables private
Makes the public interface consistent in terms of how accesses are done
on a process object. It also makes it slightly nicer to reason about the
logic of the process class, as we don't want to expose everything to
external code.

Lioncash a63e6f9dfd loader: Make the Load() function take a process as a regular reference, not a SharedPtr
A process should never require being reference counted in this
situation. If the handle to a process is freed before this function is
called, it's definitely a bug with our lifetime management, so we can
put the requirement in place for the API that the process must be a
valid instance.

Lioncash 83377113bf memory: Dehardcode the use of fixed memory range constants
The locations of these can actually vary depending on the address space
layout, so we shouldn't be using these when determining where to map
memory or be using them as offsets for calculations. This keeps all the
memory ranges flexible and malleable based off of the virtual memory
manager instance state.

Lioncash 75603b005b process/vm_manager: Amend API to allow reading parameters from NPDM metadata
Rather than hard-code the address range to be 36-bit, we can derive the
parameters from supplied NPDM metadata if the supplied exectuable
supports it. This is the bare minimum necessary for this to be possible.

The following commits will rework the memory code further to adjust to
this.

Lioncash 2ea45fe75b kernel/thread: Include thread-related enums within the kernel namespace
Previously, these were sitting outside of the Kernel namespace, which
doesn't really make sense, given they're related to the Thread class
which is within the Kernel namespace.

Lioncash 4a587b81b2 core/core: Replace includes with forward declarations where applicable
The follow-up to e2457418da, which
replaces most of the includes in the core header with forward declarations.

This makes it so that if any of the headers the core header was
previously including change, then no one will need to rebuild the bulk
of the core, due to core.h being quite a prevalent inclusion.

This should make turnaround for changes much faster for developers.

Lioncash 0cbcd6ec9a kernel: Eliminate kernel global state
As means to pave the way for getting rid of global state within core,
This eliminates kernel global state by removing all globals. Instead
this introduces a KernelCore class which acts as a kernel instance. This
instance lives in the System class, which keeps its lifetime contained
to the lifetime of the System class.

This also forces the kernel types to actually interact with the main
kernel instance itself instead of having transient kernel state placed
all over several translation units, keeping everything together. It also
has a nice consequence of making dependencies much more explicit.

This also makes our initialization a tad bit more correct. Previously we
were creating a kernel process before the actual kernel was initialized,
which doesn't really make much sense.

The KernelCore class itself follows the PImpl idiom, which allows
keeping all the implementation details sealed away from everything else,
which forces the use of the exposed API and allows us to avoid any
unnecessary inclusions within the main kernel header.

Lioncash 2beda7c2b3 kernel/process: Use accessors instead of class members for referencing segment array
Using member variables for referencing the segments array increases the
size of the class in memory for little benefit. The same behavior can be
achieved through the use of accessors that just return the relevant
segment.
