Changed "linux" target to "posix". Most of the changes are shared with
QuRT and with OSX. The Linux specific parts are in for i2c which uses
<linux/i2c.h> and <linux/i2c-dev.h>.
There is also a check for __PX4_LINUX in mavlink for a tty ioctl that is
not supported.

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.

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.
