* print_die.c: Fix typo in error message.
* print_frames.c: Do additional checks for incorrect data
when printing frame instructions to avoid dwarfdump crash..
libdwarf
* dwarf_form.c: Directly check expression length against
section length in case expression length very very large.
* dwarf_query.c: _dwarf_calculate_info_section_*() routines
made clearer and the *_start_ptr() instance also now returns
the length (via a pointer arg).
* dwarf_xu_index.c: Check data read from the section so
a wildly large columns count or slots count will be caught
and an error returned.
Moved a couple functions between source files
and made them static. A couple commentary changes.
print_frames.c, though, needed hardening against
corrupt frame data.

All data reads from an object ensure the
read is actually in a section.
It is always possible something was overlooked, but
all the reading macros and functions now do checks.

so clients can get the object
section names
(of .debug_info of .debug_types or the same with .dwo names).
Fixed indent and trailing whitespace a couple places too.
