a5513bd7e6 Implement an NCA parser and loader
Nintendo Content Archives are used to store the assets, executables
and updates of applications. They support holding either a PFS0 or a
RomFS.

An NCA's ExeFS can be loaded by placing each NSO sequentially into
memory, starting with rtld which will link them together.

Currently only decrypted NCAs are supported, encryption and BKTR
handling will be added at a later time.

db64f53cfb Implement filesystem backends for RomFS and Partition FS
RomFS is a hierarchial filesystem where each level is made up of a
linked list of files and child directories. It is used in NCAs to store
the applications icon as well as by applications themselves for
accessing assets.

Partition FS encapsulates both the HFS0 found in XCIs and the PFS0 used
for ExeFS images and NSPs, it is purely file based and has no support at
all for directories aside from the root.

bf46293fc7 Commonise executable loading infrastructure
Mapping and writing segments into memory is now handled by a common
function that can be shared between all loaders. All they need to do now
is to pack each segment into a common struct.

Fixes for control IPC (#57)
* Correctly handle -WithContext IPC Requests

They should be treated the same as the non WithContext variants.

* Only send domain data on non-control IPC responses

Control IPC doesn't make use of domains so we shouldn't send extra data
in the response.

* Add the IStorage implementation to CMakeLists

5c103ce9a6 Introduce basic VFS backing system together with two implementations
- The backing system provides a flexible way to access a a region of
   abstract memory.

- It is currently barebones and only has support for reading data but
   this will be expanded as necessary.

The current implementations are:
- OsBacking - A backing that abstracts a linux file descriptor
- RegionBacking - A backing that creates a region from a portion of an
   existing one

c76ef3730b Move to MPL-2.0
We earlier moved to LGPLv3.0 or Later. This was a mistake as what we wanted was being able to link to proprietary libraries but LGPL is the opposite and it allows linking proprietary libraries to libskyline instead. After further consideration, we've moved to MPL-2.0, it allows linking to proprietary libraries and is a standardized license as compared to adding an exception to GPL.

a0b9a635ca Fix Killing Guest Processes in KThread::Kill and fix TID/PID naming
This commit mainly fixes the problem with process leakage before where the guest process wouldn't be killed. In addition, it clears up the problem with naming differences with PID/TID where purely PID was used before but that term is generally used to refer to the PGID. So, `KProcess` has a `pid` member but `KThread` has a `tid` member.
