Past Valgrind merges skipped the "remove files that have been removed
upstream" step, so Fjalar still tracked 32 files that upstream
VALGRIND_3_23_0 does not have, some since the 3.8.1 merge (2013).
They caused real regtest failures: the stale .vgtest files made
cachegrind/tests/ann1, cachegrind/tests/diff, and memcheck/tests/memalign2
run and fail, and the files caused 27 "... is missing in EXTRA_DIST"
errors in the post-regtest makefile-consistency check.
Found with:
comm -23 <(git ls-files valgrind | sed 's|^valgrind/||' | grep -v '^fjalar/' | sort) \
<(git -C valgrind-3.23.0 ls-files | sort)
(REVISION is Fjalar's own and stays.)
- Fail if INV is unset ("cd $INV" went to $HOME) or if valgrind-old,
valgrind-new, or fjalar/valgrind is missing.
- Fail if valgrind-old or valgrind-new is not a pristine clone. Build
products there would end up in coregrind.patch and then be added to
Fjalar by "make git-update".
- Add set -e, treating diff's exit status 1 (files differ) as success
but 2 (trouble) as failure.
- Add a shebang.
- Kvasir tests: they test the Fjalar in $DAIKONDIR/fjalar, which may not be $INV/fjalar; mention test-kvasir.sh. - Files removed upstream: also handle memcheck (Fjalar's copy is valgrind/fjalar/), and add a post-merge check that Fjalar tracks no file that upstream deleted. - Regtest baseline: build in a copy of valgrind-new, never in valgrind-new itself (build products would end up in coregrind.patch); add the missing ./autogen.sh. - Binutils merge: --merge=diff3 produces conflict markers, not .rej files; new headers, SFrame, zstd, and the system bfd.h version. - .gitignore: there is no "Ignore generated test drivers" section; say where test programs go and how to find missing ones.

Review comments at @generate-patch-files.sh:
- Line 139: Update the Fjalar file-listing and tar pipeline to filter out
deleted tracked files before copying, then remove `--ignore-failed-read` and
`--warning=no-failed-read` from the `tar` invocation so other read failures stop
patch generation.
- Line 127: Update the `run_diff` invocation that generates `coregrind.patch` to
exclude `memcheck/**` from the diff, while preserving the existing `.git`
exclusion and other diff options.
Review comments at @plan-upgrade-valgrind.md:
- Around line 58-61: Update step 2 of the merge plan to reference “Correct the
files of earlier merges” and cover all three file checks in that guide section;
instruct the user to commit the corrections before running apply-patch-files.sh.
Update step 10’s reference to “the command of step 2” so it points to this
complete procedure.

Almost every line of Fjalar's Makefile.am renames Memcheck to Fjalar, so most upstream changes to memcheck/Makefile.am conflict when they are patched in. generate-fjalar-makefile.sh instead generates it from valgrind/memcheck/Makefile.am, and Fjalar's changes to the build are in valgrind/fjalar/fjalar.am, which the generated file includes. That includes the fjalar_core_decls.h consistency check. memcheck.patch omits Makefile.am, and the merge doc and the upgrade plans say to run the script after the Memcheck merge. Split out of codespecs#103.

…ts of pull requests; remove the 3-way-merge alternative The text that codespecs#98, codespecs#99, codespecs#101, codespecs#103, and codespecs#113 change in the plans is left as in codespecs#96, so that those pull requests' versions apply when they land. plan-pre-upgrade.md points to those pull requests rather than restating them. The "Alternative: a 3-way merge for Coregrind" section is removed, because codespecs#103's apply-patch-files.sh performs the same 3-way merge with git apply --3way.
Step 2 removes stale files with rm. For a file in neither valgrind-old nor valgrind-new, git.script has no git rm, so the file stayed in the index and step 10's git ls-files check still listed it. Addresses a CodeRabbit review comment.
Its "git add -u" step is not needed here: step 2 removes files with git rm, and git.script no longer exists.
