Merge libposix cleaning (lp:~vojtech-horky/helenos/misc)

Sources and headers were separated into different directories.

There are less includes from HelenOS-specific libc into public headers
of libposix. That way, the POSIX namespace is not polluted with HelenOS
specific functions (that may collide with functions declared by
other applications).
