Arun Sharma 3afd613545 [X86-64]: Instead of auto-generating _u_context_i.h, hardcode the 
necessary offsets in offsets.h as is done for other
	  platforms.  This fixes cross-builds.

David Mosberger-Tang 7923ae31a0 Re-run aclocal and automake to update Makefiles so new files (e.g., 
x86_64/gen_offsets.c) get distributed.

Arun Sharma 497b987043 Add gen-offsets to the Makefile 
This is so that the source file gets distributed and _ucontext_i.h is
generated properly on the target machine.

Arun Sharma 31440e9796 Make libunwind pass C++ exceptions correctly 
When libunwind is linked with a C++ program that throws exceptions,
the exception that's thrown is passed in %rax. However, libc's
setcontext clears %rax, causing problems.

This patch implements a setcontext that doesn't clobber rax.

TBD: Add dwarf CFI annotations

Arun Sharma 11ea1275bd [dwarf] The sword() function in Gexpr.c doesn't do what's intended. 
Yes, it casts to signed, but then converts right back to
unsigned via the return type.  Fixed thus.

Arun Sharma 8297866bd4 [x86-64] (unw_step): Further refine handling of functions without unwind-info. 
CFA should be incremented by 16 in the hope that the previous frame
may have valid unwind info.

Also increase the default frame pointer recognition heuristic from 4k
to 16k.

Arun Sharma 06d2ffa41a [x86-64] (unw_step): Improve handling of functions which lack unwind info. 
If following the frame-chain leads to a frame >= 4KB away, we conclude that
the frame-pointer isn't really valid.

Arun Sharma 60b7af702a (dwarf_find_save_locs): Add a comment. 
Now that dwarf_find_save_locs() not just finds the save-locations but
also updates the cursor-state, document this fact (the function really
is misnamed now).

David Mosberger-Tang 8c94e12429 (_UPT_find_proc_info): Fix potential crash due to uninitialized pointer. 
Be sure to clear pi->unwind_info when looking up the kernel table and
not needing the unwind-info.  Otherwise, _UPT_put_unwind_info() may
erroneously call free() on the pointer, even though that space wasn't
malloc'd, leading to crashes..

David Mosberger-Tang af2503e223 Fix bug in libunwind-ptrace which can cause reading of random data. 
(maps_next): After reading less than a full buffer of data, copy
remaining data to the top of the buffer so as to maintain the
invariant that all data between mi->buf and mi->buf_end is valid.
This avoids maps_next() parsing uninitialized data.
