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

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.

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

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.

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

Be sure to clear pi->unwind_info when looking up the kernel table and

erroneously call free() on the pointer, even though that space wasn't
malloc'd, leading to crashes..

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.

239ea4e7ea Implement for real. Note: this version is currently broken. 
We don't pass sigmask the way this routine expects because it
can't work.

(struct callback_data): New structure.
(linear_search): New function.
(callback): Convert to getting auxiliary info passed via a pointer to
	a callback_data structure, rather than an unw_dyn_info_t
	structure.
	Keep track of the maximum load address in max_load_addr.
	If an object doesn't have a binary search-table, fall back
	on a linear search.
(dwarf_find_proc_info): Fill in callback-data structure before calling
	dl_iterate_phdr().  Upon returning, check whether
	cb_data.single_fde is set and, if so, return directly, without
	searching the DWARF unwind-table.
(dwarf_search_unwind_table): Adjust for renaming of
	dwarf_parse_fde() to dwarf_extract_proc_info_from_fde().
	If IP doesn't fall into the IP-range of the FDE-entry found
	by the search, return UNW_ENOINFO.
