Emulator 30.0.15 Canary

Emulator 30.0.15 is now available in the Canary and Dev channels. Changes:

• We've seen issues running the Windows emulator with Riot Vanguard active. The Windows emulator now detects Vanguard anti-cheat and pops up a warning message if Vanguard is detected.
• The emulator now prints a warning if unsupported options are passed to -prop (Only qemu.* props are supported).
• When using the Linux emulator embedded in Studio, we found that if this is done through Chrome Remote Desktop, there is a bug where XDG_RUNTIME_DIR is not set and may cause the embedded emulator to fail to appear due to the emulator discovery files being placed in XDG_RUNTIME_DIR.
• https://bugs.chromium.org/p/chromium/issues/detail?id=1077449
• As a workaround, the emulator now falls back to using discovery files in a possibly-different directory that is based on user UID (/run/user/<uid>).
• Emulator icons updated to reflect Studio 4.1 branding.
• When building the emulator on Windows, there should be less chance of seeing flaky failures to write to files. (Windows build instructions: https://android.googlesource.com/platform/external/qemu/+/refs/heads/emu-master-dev/android/docs/WINDOWS-DEV.md)
• gRPC endpoint now supports sending SMS to the device.
• Updated WebRTC libraries to M83.
• darwinn pipe endpoint has been removed.
• When hw.gltransport=virtio-gpu-pipe, performance is improved by not spinning on the host in transfers from host to guest.

ARM64 host support

• Linux emulator source code now supports cross compilation from x86_64 to arm64 hosts, enabling running arm64 system images with KVM virtualization and host side rendering. Currently, only -gpu swiftshader_indirect (Swiftshader arm64 host rendering) is supported, but a compatible set of host GPU libEGL/libGLESv2/libGLESv1_CM libraries may also be used via replacing the libraries in lib64/gles_swiftshader with them and then relaunching with -gpu swiftshader_indirect. Snapshots may also not be working (add -no-snapshot to the command line). Instructions: 

pip install absl-py

pip install urlfetch

sudo apt-get install crossbuild-essential-arm64
