ef29eade44 This patch eliminates one system call per unwind by not using the 
getcontext in libc.

Also cleanup the namespace (check-name-space passes on x86_64 now).
Replace uses of offsets.h with ucontext_i.h.
Rename _x86_64_setcontext to _Ux86_64_setcontext.

TBD: Add CFI annotations for get/setcontext.

3842dac733 Add initial ARM and MIPS support. To support this, also enable the 
reading of .debug_frame sections (used in lieu of .eh_frame sections
when they're not available).

e6b9f350f7 Introduce a tdep_get_func_addr_hook() in the ELF lookup_symbol() 
routine and add address-space argument.  This is needed because on
PPC64, a the function-name symbol refers to a function descriptor
(unlike, for example, on ia64, where the @fptr() operator is needed to
refer to a function descriptor).  Thus, in order to look up the name
of a function, we need to dereference the function descriptor.  To
make matters more "interesting", the function descriptors are normally
resolved by the dynamic linker, so we can't get their values from the
ELF file.  Instead, we have to read them from the running image, hence
the need for the address-space argument.

This is so that the source file gets distributed and _ucontext_i.h is
generated properly on the target machine.
