aarch64 defines a huge __reserved field in sigcontext. Cut it down
to only the used FP fields.
unw_cursor_t can also be cut down a bit, while still maintaining some reserved space.
Attached is a corrected version of my previous patch for aarch64 PLT
entry recognition. The comparison in the is_plt_entry function should
have been:
ret = (((w0 & 0xff0000009f000000) == 0xf900000090000000)
&& ((w1 & 0xffffffffff000000) == 0xd61f022091000000));
unw_is_signal_frame() returns <= 0 if not a signal frame. Several places in
code were only checking for a "if (unw_is_signal_frame())", or
"if (!unw_is_signal_frame())".
Set local_addr_space.big_endian flag according to current target
endianness. Before it was set by memset to 0, which corresponds
to little endian and it worked perfectly fine for aarch64.
But it breaks aarch64_be because dwarf_readu16, dwarf_readu32,
etc functions do not read values correctly since they operate
with wrong idea about current target endianness.

The attached patch simply modifies the Debug statements for aarch64 to use
%lx instead of %x. Tested by compiling for aarch64 using a cross-compiler.
