a44061398c Remove unused frame.h header, sigcontextinfo.h macros. 
The glibc-internal header frame.h was used in the old
debug/backtrace.c but is now unused.  Similarly, there are some
sigcontextinfo.h macros that are used nowhere in glibc -
ADVANCE_STACK_FRAME and FIRST_FRAME_POINTER were used in the old
debug/backtrace.c, while SIGCONTEXT_EXTRA_ARGS, GET_FRAME, GET_STACK
and CALL_SIGHANDLER were unused even before the removal of that old
implementation (beyond uses of SIGCONTEXT_EXTRA_ARGS in definitions of
CALL_SIGHANDLER).  This patch removes all the unused frame.h headers
and definitions of those macros.

Tested with build-many-glibcs.py.

RISC-V: Linux ABI 
Linux-specific code that is required for maintaining ABI compatibility.
This doesn't contain the actual system call interface, that is split out
in order to avoid having a patch that's too big.
