Various fixes/improvements to HLE of 3DS services, mostly cleans up GSP call decoding

Update FlipFramebuffer - makes converting the raw framebuffer slightly faster

Less calculations + fix

- added a helper function for getting command buffer for services
- fixed bug where GSP DMA was incorrectly being done in DataSynchronizationBarrier (instead of gsp_TriggerCmdReqQueue)

- added stubbed HLE syscall functions for svc_GetResourceLimit and svc_GetResourceLimitCurrentValues

- handle RD in STREX/STREXB

- added stubs for GetResourceLimit and GetResourceLimitCurrentValues SVCs

- moved instruction decoding to coprocessor HLE module

- added stub for SVC CreateAddressArbiter
- added OutputDebugString SVC

- updated load launcher.dat function to use ARM11 format hack

Travis CI script

fix for issue Linux build #9, not sure why this is broken but its unused code I'm just getting rid of it

removed commented out line - this was for an unimplemented MRC call, no longer need to leave this here

hackish but working way to set the framebuffer location to VRAM (used in ARM11 demos tested thus far, e.g. yeti3DS)
