Do much much more testing to ensure we do not
run off the end of section or accept a bogus

fdes were not printing properly.
We were testing the wrong thing to determine if
we should print.

The code for frames was basically ok.
But clearer now with better comments for eh_frame.
And clearer 'no entry' for fde augmentation bytes.

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.
indentation. No interfaces changed. One new and
not very significant (to most people) interface added which
returns a count of abbreviations in an abbreviation section.
