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.

Emmanuel Gil Peyrot c197ce2180 Kernel: Add a Directory object and a getter for it from an Archive object. 2014-09-17 14:35:46 +00:00
Lioncash ab4648d3ca Core: Use std::array for managing kernel object space
These avoid relying on memset for clearing the arrays.

Lioncash 98fa3f7cba Core: Alter the kernel string functions to use std::string instead of const char*.
Most functions already operate on std::strings. This also removes the need to manually null terminate thread names.
