See hardware/libhardware/include/hardware/qemu_pipe.h for the API
implemented by the library. It enables very fast reads/writes between
the guest system and specific emulator services.
Define BUILD_LIBQEMU_TESTS=true in your environment to build the
test programs (a simple host ping-pong server, and a benchmark
guest program).
You can invoke them with:
1/ Testing TCP pipes:
host: test-libqemu-1 -tcp 8012
guest: test-libqemu-2 -pipe tcp:8012
Alternatively
guest: su
test-libqemu-2 -tcp 8012
2/ Testing Unix pipes:
host: test-libqemu-1 -unix /tmp/libqemu-socket
guest: test-libqemu-2 -pipe unix:/tmp/libqemu-socket
3/ Testing internal pingpong server (within the emulator)
host: /* nothing to do */
guest: test-libqemu-2

Unfortunately, we need to keep duplicate libraries under sdk/emulator/
to avoid breaking a few internal branches.

emulator: Remove the global Make variable trick for emulator-specific system modules.
Remove a sad trick that was used to smoothly move the platform-specific emulator
modules from sdk/emulator/ to development/tools/emulator/system without creating
build conflicts.
Now that the sdk/ modules have been removed, we can get rid of the guard variable.

This copies the platform-specific emulator modules from sdk.git into
development.git/tools/emulator/system/. Note the use of guard variables
to prevent clashes when the original modules are still in the tree.
The goal is to submit this and https://review.source.android.com/#change,21737,
then later remove the modules from sdk.git when we move the internal sdk branch
to the appropriate tools_rXXX branch.
