git-debrebase: new-upstream: Fix handling of epochs.

Dpkg::Version->version() is only the middle part.  ->epoch() doesn't
have the colon.  This is inconvenient enough that we convert it to a
string and use a regexp :-/.

dgit: push_source no longer cleans the tree.

This is no longer needed because we always build in a playtree.

Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>

dgit: build_source mostly uses a playtree, not $maindir

In particular, it uses a playtree unless we are trying to include
uncommitted changes in the source package (which is not supported in
split brain mode).

This change allows build_source to respect $buildproductsdir.  It will
also enable, later, building a source package from HEAD, or arbitrary
git ref, when the working tree is dirty.

This change also requires modifying build_prep to only conditionally
clean $maindir.  It should clean $maindir only when it's $maindir that
we're packing into a source package, or when we are running any
builder in $maindir.

When we are using a playtree we must build the changes file there too,
because dpkg-genchanges cannot be persuaded to look for the .dsc
anywhere but ../.

Right now build-source still cleans the tree needlessly.

We need to change the test suite to not expect a clean unless running
a builder:

dgit now cleans the tree only when including uncommitted changes in a
source package, and when running a builder in $maindir.  The code in
lib-build-modes does not test the including of uncommitted changes in
a source package.  Thus, it should expect the tree to be cleaned only
when running a builder.

Also, we need to not expect a clean with sbuild, for the same reason.

* cmd_push_source

  This one is most complicated.  It already calls prep_push, which
  does a variety of things which overlap with build_prep.  The things
  which are in build_prep but not in prep_push are:
   - notpushing (via build_prep_early), which seems to be a mistake
   - clean_tree(), which is needed, so we add it (for now...)
   - build_maybe_quilt_fixup, which is needed, so we add it
   - remove old changes, which is not actually needed

* cmd_build, cmd_gbp_build

  build_prep was already called by the if arm which didn't call
  build_source; so we can just move it up outside the if.  No
  functional change here.

Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>

dgit: Disregard *_multi.changes for .changes ambiguity purposes

The changes file ambiguity problem arises because dgit does not know
what architecture changes file the build is going to generate.  (To
know that it would have to delve even more into the command line
options the user is passing through dgit to the builder.)

dgit --always-split-build generally makes a _multi.changes file,
because it merges source changes with binaries from the build.  We are
going to make --always-split-build the only way things are done.  This
would result in lots more situations where --rm-old-changes is needed.

However, actually, we can assume that the builder does not generate a
*_multi.changes.  That will allow us to spot the builder-generated
changes file even if there is already a dgit-generated *_multi.changes
file from a previous build.

So: disregard _multi.changes, both when pre-checking for confusing
files, and when actually figuring out what the build produced.

Arranges for all the refs in each playtree to be saved in the parent's
ref namespace.

This is going to be used when running git-gc when saving artifacts.

test suite: Drop t-ok from setup/*

t-ok is going to save artifacts, which we don't want these to do.

It is not actually needed.  All it does that is useful is the fsck,
which the actual tests will do.

test suite: Use  dch -r -D sid ''  not  dch -r sid.

Bizarrely,
   dch -r [-D suite]
runs $EDITOR but
   dch -r [-D suite] weevils
ignores `weevils' but does not run $EDITOR.  This is #903598.

Apparently, this is well known, and convention is to pass ''.
See https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=903598#8.

So use that.

Closes:#903441.

test suite: Factor out t-dch-commit-r

The pattern `dch -r sid' is actually wrong and we will want to change
it.  See #903441 and #903598.  For future-proofing, factor this out
before we fix it.
