Added FS functions to Archive and Archive_RomFS

Removed unused citra.h

Common: Add a clamp function to math_utils.h

ARM: Remove a forgotten const in vfp.

Revert "Removed redundant loop in EmuThread::run()"

Use Qt5 by default for citra-qt project.

Core: Use std::array for managing kernel object space

Common: Get rid of an unnecessary forward declaration in symbols.h

These avoid relying on memset for clearing the arrays.

Core: Alter the kernel string functions to use std::string instead of const char*.

SVC: Added support for svc_GetSystemTick.

Changed HLE function return methods to be static inline functions.

Common: Don't return a reference to a string when calling GetName in symbols.cpp

CMake Cleanup

Returning a copy of the string is what was likely meant to be done.

Most functions already operate on std::strings. This also removes the need to manually null terminate thread names.

Common: Correctly set ptr to null if mmap fails in memory_util

Removed redundant loop in EmuThread::run()

Replace insecure temporary file creation with devshm.

Common: Move header guards over to pragma once.

Core: Fix undefined behavior in mem_map_funcs' WriteBlock function

Core: Fix a formatting error in svc.cpp

entry_point would not be added to the string. Also used StringFromFormat
so that the buffer is unnecessary.

On POSIX systems mmap will return MAP_FAILED ((void*)-1) instead of a null pointer.

Also replaced C headers with the C++ equivalent ones

Bootmanager: changed `filename` to std::string

Simplified if-tree in extended_trace.cpp
