We do not modify `_UPT_reg_offset', so let's set it `const'. Given that
the array is exported, it's technically possible that some library user
is actually modifying the content, but does not seem really all that
likely.
Move ptrace-independent code from src/ptrace/_UPT_find_proc_info.c
to src/dwarf/{G,L}find_unwind_table.c. Name this moved function
dwarf_find_unwind_table().

This is a common part of struct UPT_info
and struct UCD_info (to be introduced later).
Make _UPTi_find_unwind_table function operate only on this part
of struct UPT_info.

This keeps the definition on IA64 and all the other architectures in sync with
the declaration of _UPTi_find_unwind_table. This also mimics the behaviour of
what's done for local unwinding and allows the function to provide more than
one way to undwind.

Change _UPTi_find_unwind_table to also look for the ARM specific unwind
information. Adjust the ARM unwind code to read memory using the accessor
routines.

On ia64-hpux version 11.31, <sys/ptrace.h> has been removed.
This patch adds a configure check for this header file, and only
includes <sys/ptrace.h> if it exists.
