libdwarf:
    * dwarf_alloc.c: Refactored and added relevant commentary.
      Added a check for debug_types in dwarf_dealloc().
    * dwarf_init_finish.c: Corrected a comment and made one line
      declation-is-initialization.
    * dwarf_opaque.h: Added commentary.
Changes support DW_FORM_exprloc.
Changes support, to a limited extent, DW_FORM_GNU_ref_alt
       and DW_FORM_GNU_strp_alt.
Updated libdwarfdoc about DW_FORM_exprloc support.
Final small changes for a new release.
Ensuring it builds where it should.
Revised CPTOPUBLIC so it gets everything for BLDLIBDWARFTAR.
So the tar version is complete.
Switched the tsearch testcase text to gzip to save
space as few will need to use the testcase data.
Added more 'echo' commentary lines to BLDLIBDWARFTAR
libdwarf/dwarf_alloc.c: Removed a long list of if()
tests referring to debug section addresses
in favor of a single dwarf_tfind().
It will continue to work over time, the earlier
approach was error-prone in the face of new DWARF
sections.
Just fixing trailing-whitespace and a pair of indent
issues in libdwarf.
Tweaked the overall Makefile so the default just builds
libdwarf and dwarfdump[2]. Nothing else.
Refined the comments about the build (in README at the top level).
Adding documentation to the tsearch uses: tsearch/ESSAY.txt
Added additional wording to tsearch/ESSAY.txt
dwarfdump2: removed trailing whitespace from *.list files.
dwarfdump2: print_die.cc had incorrect indent in one line.
dwarfdump: removed trailing whitespace from *.list files.
