aarch64: fix return value if getcontext was used to acquire the current context.
...
x0 hast to be 0 in case setcontext is called with a context acquired by getcontext.
Thus x0=0 must be stored in getcontext.

aarch64: remove usage of FUNC macro for clang
...
Clang's arm64 assembler does not support multiple directives on a single
line. C macros ALWAYS expand to a single line.

project: move freestanding include headers
...
This is needed because in libucontext.h we include "libucontext/bits.h".
We therefore need to have bits.h in somepath/libucontext/bits.h. In the
Makefile, somepath/freestanding/bits.h was copied to the right path but
in the meson build system, the include copy happens at the end.
