- Use read_user_data() function for unwinding based on frame pointers (the same way as in dwarf_unwind.c/eh_unwind.c). This fixes broken frame pointer backtraces on some devices. - A few minor changes.

Problem is that on systems with a 64-bit kernel and 32 bit userspace, read_user_data function reads 32-bit value into 64-bit uninitialized variable, so high half of the variable might be dirty. Use 32-bit temporary variable in such cases.
