Yuri Kunde Schlesner c2588403c0 HLE: Revamp error handling throrough the HLE code 
All service calls in the CTR OS return result codes indicating the
success or failure of the call. Previous to this commit, Citra's HLE
emulation of services and the kernel universally either ignored errors
or returned dummy -1 error codes.

This commit makes an initial effort to provide an infrastructure for
error reporting and propagation which can be use going forward to make
HLE calls accurately return errors as the original system. A few parts
of the code have been updated to use the new system where applicable.

One part of this effort is the definition of the `ResultCode` type,
which provides facilities for constructing and parsing error codes in
the structured format used by the CTR.

The `ResultVal` type builds on `ResultCode` by providing a container for
values returned by function that can report errors. It enforces that
correct error checking will be done on function returns by preventing
the use of the return value if the function returned an error code.

Currently this change is mostly internal since errors are still
suppressed on the ARM<->HLE border, as a temporary compatibility hack.
As functionality is implemented and tested this hack can be eventually
removed.

citra emulator

Travis CI Build Status

An experimental open-source Nintendo 3DS emulator/debugger written in C++. Citra is written with portability in mind, with builds actively maintained for Windows, Linux and OS X. At this time, it only emulates a subset of 3DS hardware, and therefore is generally only useful for booting/debugging very simple homebrew demos. Citra is licensed under the GPLv2. Refer to the license.txt file included. Please read the FAQ before getting started with the project.

For development discussion, please join us @ #citra on freenode.

Development

If you want to contribute please take a took at the Contributor's Guide, Roadmap and Developer Information pages. You should as well contact any of the developers in the forum in order to know about the current state of the emulator.
