Update nihstro submodule to the initial release version.

Asserts: Use lambdas to keep assertion code away from the main code path

Includes more opcodes to implement in the future.

Build app bundles on OS X. Fixes the issue where the menubar would not appear.

default_ini.h: Put comments on their own lines

Apparently inline comments is not necessarily standard in the INI format, and our parser was erroneously parsing the comments as values.

Fixed EmuWindow typo (fixes OSX build)

Set framebuffer layout from EmuWindow.

GPU/Textures: Fixed ETC texture decoding.

Add profiling infrastructure and widget

Removed swap code redundancy and moved common swap code to swap.h

 Services: Moved the PTM and APT services to their own folder

This coincidentally fixes an issue about the PTM service failing to create its SharedExtSaveData archive due to the FS service not being initialized by the time the creating code runs.

Ideally I'd like to move each process to its own folder, and have a single file per process that registers the service classes, which would be in their own files inside that folder. Then each service class would just call functions from the process to complete the commands.

vfp: Get rid of warnings

GPU: Added RGB565/RGB8 framebuffer support and various cleanups.

- Centralizes color format encode/decode functions.
- Fixes endianness issues.
- Implements remaining framebuffer formats in the debugger.

Services/AM: Stubbed TitleIDListGetTotal and GetTitleIDList.

They will always return 0 titles for every media type for now.
This is needed to boot Home Menu further

Services/FS: Stubbed CardSlotIsInserted to always return false

result: Make comparison operators take references

Services/PTM: Stubbed PTM_Sysm::IsLegacyPowerOff.

MSVC 2013 (at least) doesn't use QueryPerformanceCounter to implement
std::chrono::high_resolution_clock, so it has bad precision. Manually
implementing our own clock type using it works around this for now.

We won't be emulating this for the foreseeable future and it is needed for Home Menu to boot further

This allows the Home Menu to boot further

Added RGBA5551 compatibility in the rasterizer

arm_disasm: Show conditional code for BKPT instructions.

arm_disasm: Remove unused variable

This allows Virtual Console games to display properly.

Changed cond_to_str to take a uint32, since unsigned numbers are only ever passed to it, and this can be a source of warnings for some compilers (also indexing an array without bounds checking a signed number is kind of iffy).

Also declared an array as static, as it's only used in this translation unit.

It's unnecessary to make copies for simple comparisons like this.

GPU: Implemented bits 3 and 1 from the display transfer flags.

Bit 3 is used to specify a raw copy, where no processing is done to the data, seems to behave exactly as a DMA.
Bit 1 is used to specify whether to convert from a tiled format to a linear format or viceversa.
