PptRelation.init_hierarchy (old declaration format) and init_hierarchy_new now share connect_conditionals and finish_hierarchy, so the old format also creates equality views for childless non-leaves. A non-leaf with no children has its splitters removed. New methods PptRelation.init_hierarchy_for_decl_format and PptTopLevel.create_equality_view replace duplicated code. Split from codespecs#858.

New method PptTopLevel.is_dataflow_leaf, also used by Daikon.setupEquality, identifies the ppts that get their invariants from samples. setup_childless_nonleaves now ignores leaves, and finish_hierarchy removes the splitters of a childless ppt only if it is not a leaf. This avoids assertion failures and lost conditional invariants for old-format CLASS ppts, :::POINT leaves with splitters, leaves when the equality optimization is disabled, and the not-yet-connected leaves in MergeInvariants. MergeInvariants now uses init_hierarchy_for_decl_format.

- Around line 4713-4725: Update PptTopLevel.is_dataflow_leaf() to use the
hierarchy parent’s declared PptType when available, including for PptConditional
instances: treat only POINT and SUBEXIT as leaves. Preserve the existing
PptName-based check as a fallback when the type is null.

Convert every version 1 .decls and .dtrace test input to the version 2 format, in preparation for dropping support for version 1 files. The converted inputs produce the same output, with two exceptions: * pine_mdiep loses one invariant over a two-dimensional variable, which version 2 cannot represent. * Nine more splitters compile, because the version 2 declarations let the splitter generator find array variables. Also delete test inputs that no test uses, and delete tests/diff-tests/StackAr, which has been excluded from testing (and broken) since 2010.
Daikon no longer reads version 1 .decls and .dtrace files, and reports an error when it encounters one. Remove FileIO.new_decl_format and all code that was used only for version 1 files, including the name-based program point hierarchy (MergeInvariants now uses the declaration-based one) and the remove_post_vars configuration option. Remove the Perl front end (dfepl), which produced version 1 files. Port convertcsv.pl and the cluster analysis scripts to version 2, and remove scripts that processed only version 1 files.

….pl unescaping, remove version 1 leftovers * developer.texinfo: release snippets no longer test for the deleted front-end/ directory; example .decls is now in version 2 format; clarify that a file with no decl-version record is read as version 2. * CHANGELOG.md: accurately describe what identifies a version 1 file. * convertcsv.pl: unescapeDecl now handles \n and \r like FileIO.unescape_decl. * Remove lwpp-init.pl (only used with the removed lwpp.pl) and unused version 1 Kvasir goal files for SimpleDisambigStructTest.

…trace, cluster scripts - ppt_perc: never exclude GLOBAL/OBJECT/CLASS ppts (they are parents of included ppts); read ppt names via FileIO.declared_ppt_name, which applies user_mod_ppt_name. - MergeInvariants with a .decls file: create combined exits before init_hierarchy, and clean the ppt map for merging on both paths. - SplitDtrace: handle traces without declarations; pass header records through. - decls-add-cluster.pl: link the cluster variable to its parents. - dtrace-count.pl, dtrace-indent.pl: match declaration records exactly. - Remove simplify_expression/simplify_variable_names and the unused return value of read_decl_version.

…tDtrace comments - FileIO.is_parent_only_ppt_name: use PptName rather than a substring match on "GLOBAL". - read_ppt_decl: reuse declared_ppt_name to parse the ppt name. - SplitDtrace: use new FileIO.is_header_record, which also recognizes comment records. - MergeInvariants: clean ppts for merge only when reading .inv files. - developer manual: there is no longer a Perl front end.

Graphviz and netpbm were used only to build the dfepl-flow image. Also restore an attributed historical note, format the changelog entry as a bullet, and clarify that the input-language string is arbitrary.
…w: faster ppt_included, share is_declaration_header, sort-dtrace.pl header paragraphs
…te declarations Read records a paragraph at a time, which is faster; end a record only at an empty line, as Daikon does. Share the record loop via for_each_record, which reads through ARGV so that perl -i works. Give ListImplementors its own record kind. Keep indented comments with the following variable in sort-dtrace.pl. Reject unknown keys in program point declarations. Remove the unused check_no_cluster_var.
…arations and escaping * util_daikon.pm: accept \r\n line endings; process paragraphs by offset (linear time); reject a variable declared twice or lacking var-kind, dec-type, or rep-type; build error messages only when needed. * decls2comp.py: list variables with negative comparability on a "-1:" line. * dtrace-diff.pl: read declarations from the traces (decls file optional); escape names in all messages; strip comments with one regex; remove the no-op --ignore_exitno option. * convertcsv.pl: match -decl variables to columns by either form of the name, die if none matches, and write the declared names.

This depends on #880, which removes support for the version 1 file format (and with it the old
init_hierarchy); this PR includes #880's changes, so it will be smaller once #880 is merged. It is independent of #876; #877 depends on both.Originally this PR made the old- and new-format hierarchy code share their common parts. #880 leaves only one hierarchy function, so this PR now contains just the parts that are still relevant.
Behavior changes in
PptRelation.init_hierarchy:setup_childless_nonleaves. This replaces an assertion that such a point is an OBJECT, CLASS, or ENTER point; it also handles a declared combined exit that has no numbered exits.Refactorings:
PptTopLevel.is_dataflow_leafreplaces the leaf test inDaikon.setupEquality.PptTopLevel.create_equality_viewreplaces duplicated code.
