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.

Such strings in DWARF are created by 'fuzzing' or
by a bug in a compiler or linker.

exclusively. Deleting the CURRENT_VERSION_STAMP* macros.
The intent is to improve readability given we now have
4 versions of DWARF to deal with.
dwarf_arange.c(dwarf_get_aranges_list): Remove the length variable
as its calculated value is unused. rename length to area_length
for clarity. Calculate arange_ptr_past_end early and
correctly. Ensure that the test for version 4 is a >=
to reflect normal standards upgrades.
dwarf_die_deliv.c(dwarf_find_offdie_CU_Context): Add commentary
about offsets and lengths for clarity.
Rename fields for clarity about local vs global offset.
Use the newly named fields for precise tests of section overflow of
a type unit.
Other changes in libdwarf were additions and modifications of commentary.

not very significant (to most people) interface added which
returns a count of abbreviations in an abbreviation section.
