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.

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.

(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.
