cext: move util.h to cext tree Since util.h isn't useful in plain C module, it should be placed in CPython extension directory.

cext: move back finalization of dirstateTupleType where it should be

cleanup: reuse existing wctx variables instead of calling repo[None] Incidentally, this apparently means we load .hgsub one time less as well, which affects a test case.

localrepo: extract bookmarkheads method to bookmarks.py This method is only used internally by destutil, and it's obscure enough I'm willing to just move it without a deprecation warning, especially since the new method has more constrained functionality. Design-wise I'd also like to get active bookmark handling folded into the bookmark store, so that we don't squirrel away an extra attribute for the active bookmark on the repository object.

tests: avoid renamed files triggering check-commit failures I had to flag some revisions to not undergo check-commit scrutiny today to get the tests to pass, because they renamed files that had existing failures which we're not cleaning up. Let's prevent that in the future by using the extended git diff format to elide moved code.

dispatch: make request accept additional reposetups chg needs special logic around repo object creation (like, collecting and reporting repo path to the master server). Adding "reposetup" to dispatch.request seems to be an easy and reasonably clean way to allow that.

cext: extract revlog/index parsing code to own C file parsers.c is ~3000 lines and ~2/3 of it is related to the revlog index type. We already have separate C source files for directory utilities and manifest parsing. I think the quite unwieldy revlog/index parsing code should be self-contained as well. I performed the extraction as a file copy then removed content from both sides in order to preserve file history and blame. As part of this, I also had to move the hexdigit table and function to a shared header since it is used by both parsers.c and revlog.c # no-check-commit

debugcommands: use temporary dict for its command table Instead, load the table by commands.py so the debug commands should always be populated. The table in debugcommands.py is unnamed so extension authors wouldn't be confused to wrap debugcommands.table in place of commands.table.
