Lioncash 5167d1577d kernel/handle_table: Allow process capabilities to limit the handle table size
The kernel allows restricting the total size of the handle table through
the process capability descriptors. Until now, this functionality wasn't
hooked up. With this, the process handle tables become properly restricted.

In the case of metadata-less executables, the handle table will assume
the maximum size is requested, preserving the behavior that existed
before these changes.

Lioncash 6ff5135521 kernel/process: Introduce process capability parsing skeleton
We've had the old kernel capability parser from Citra, however, this is
unused code and doesn't actually map to how the kernel on the Switch
does it. This introduces the basic functional skeleton for parsing
process capabilities.

Lioncash d21b2164e9 kernel/errors: Clean up error codes
Similar to PR 1706, which cleans up the error codes for the filesystem
code, but done for the kernel error codes. This removes the ErrCodes
namespace and specifies the errors directly. This also fixes up any
straggling lines of code that weren't using the named error codes where
applicable.

Lioncash 1fb4bebb63 kernel/errors: Remove now-unused, unnecessary, error codes
Now that we've gotten the innaccurate error codes out of the way, we can
finally toss away a bunch of these, trimming down the error codes to
ones that are actually used and knocking out two TODO comments.

Lioncash b703aba622 kernel/server_port: Change error case return value in Accept() to ERR_NOT_FOUND
This is what the kernel does in this instance.

These are now entirely unused and can be removed.

Lioncash c7c346a15d kernel/error: Add error code for invalid pointers
The kernel appears to return 0xE601 for this situation. Particularly in
svcWaitSynchronization, svcReplyAndReceive, and svcGetThreadContext

Lioncash 6df09f5b76 kernel/error: Add error code for closed sessions
The kernel appears to return 0xF601 for this case.

Lioncash 72e9cb523e svc: Add missing address range sanitizing checks to MapMemory/UnmapMemory
This adds the missing address range checking that the service functions
do before attempting to map or unmap memory. Given that both service
functions perform the same set of checks in the same order, we can wrap
these into a function and just call it from both functions, which
deduplicates a little bit of code.

Lioncash 541c550753 kernel/svc: Implement svcGetThreadContext()
Now that we have all of the rearranging and proper structure sizes in
place, it's fairly trivial to implement svcGetThreadContext(). In the
64-bit case we can more or less just write out the context as is, minus
some minor value sanitizing. In the 32-bit case we'll need to clear out
the registers that wouldn't normally be accessible from a 32-bit
AArch32 exectuable (or process).

Lioncash 7bd2faad9a kernel/svc: Sanitize heap sizes within svcSetHeapSize()
The kernel checks if the given size is a multiple of 2MB and <= to 4GB
before going ahead and attempting to allocate that much memory.

Lioncash 50a5d09d32 kernel/errors: Amend error code for ERR_NOT_FOUND
This is the value returned by the kernel for svcConnectToNamedPort() if
the named port cannot be found.

Lioncash f708207ae6 kernel/error: Amend error code for ERR_MAX_CONNECTIONS_REACHED
We can make this error code an alias of the resource limit exceeded
error code, allowing us to get rid of the lingering 3DS error code of
the same type.

Lioncash bfb0c87b7b kernel/error: Amend error code for ERR_PORT_NAME_TOO_LONG
We can treat this as an alias of TooLarge for documentation purposes.
This also lets us get rid of another lingering 3DS-related error code.

Lioncash 81ca46dd17 kernel/error: Add error code for the handle table being full
This replaces the lingering 3DS constant with the proper one, and
utilizes it within HandleTable's Create() member function.

Subv e81a2080eb Kernel: Corrected the implementation of svcArbitrateLock and svcArbitrateUnlock.
Switch mutexes are no longer kernel objects, they are managed in userland and only use the kernel to handle the contention case.
Mutex addresses store a special flag value (0x40000000) to notify the guest code that there are still some threads waiting for the mutex to be released. This flag is updated when a thread calls ArbitrateUnlock.

TODO:
* Fix svcWaitProcessWideKey
* Fix svcSignalProcessWideKey
* Remove the Mutex class.
