The previous name implied some kind of daemon. AppState is
aggregated state of an application's running state and interfaces
to request app termination, and check app state.

Modified uint32_t casts of pointers to unsigned long for portability.
It otherwise breaks on x86_64.
Added _PX4_IOC to handle the conflice between _IOC on Linux and NuttX.
Removed use of px4::ok() because it cannot be used in a thread based
implementation. Changed to use px4::AppMgr which uses ok() on ROS.
Removed up_cxxinitialize.c from Linux build.

Uncomment the following line in setup.mk and comment out the line above
to enable the Linux build.
export PX4_TARGET_OS = linux
The build uses the clang compiler by default. The final bundled executable
is mainapp located in:
Build/linux_default.build/mainapp
When you run mainapp it will provide a list of the built-in apps. You can
type in the commands to run such as:
hello_main start
Because the Linux build is threaded and does not support tasks or processes,
it cannot call errx, exit() _exit(), etc. It also requires unique scoped
variables to test if a thread is running or if an application should exit.
The px4::AppMgr class was added in px4_app.h for this purpose. The
hello sample app demonstrates how this is used.
