The -Xours/-Xtheirs merge options were originally defined as a way
to "force" the resolution of 3way textual merge conflicts to take
one side without using your editor, hence did not even trigger in
situations where you would normally not get the <<< === >>> conflict
markers.
This was improved for binary files back in 2012 with a944af1d
("merge: teach -Xours/-Xtheirs to binary ll-merge driver",
2012-09-08).
Teach a similar trick to the codepath that deals with merging two
conflicting changes to symbolic links.

Travis CI dutifully builds and tests each new branch tip, even if its
tree has previously been successfully built and tested. This happens
often enough in contributors' workflows, when a work-in-progress
branch is rebased changing e.g. only commit messages or the order or
number of commits while leaving the resulting code intact, and is then
pushed to a Travis CI-enabled GitHub fork.
This is wasting Travis CI's resources and is sometimes scary-annoying
when the new tip commit with a tree identical to the previous,
successfully tested one is suddenly reported in red, because one of
the OSX build jobs happened to exceed the time limit yet again.
So extend our Travis CI build scripts to skip building commits whose
trees have previously been successfully built and tested. Use the
Travis CI cache feature to keep a record of the object names of trees
that tested successfully, in a plain and simple flat text file, one
line per tree object name. Append the current tree's object name at
the end of every successful build job to this file, along with a bit
of additional info about the build job (commit object name, Travis CI
job number and id). Limit the size of this file to 1000 records, to
prevent it from growing too large for git/git's forever living
integration branches. Check, using a simple grep invocation, in each
build job whether the current commit's tree is already in there, and
skip the build if it is. Include a message in the skipped build job's
trace log, containing the URL to the build job successfully testing
that tree for the first time and instructions on how to force a
re-build. Catch the case when a build job, which successfully built
and tested a particular tree for the first time, is restarted and omit
the URL of the previous build job's trace log, as in this case it's
the same build job and the trace log has just been overwritten.
Note: this won't kick in if two identical trees are on two different
branches, because Travis CI caches are not shared between build jobs
of different branches.

It seems that Travis CI creates the cache directory for us anyway,
even when a previous cache doesn't exist for the current build job.
Alas, this behavior is not explicitly documented, therefore we don't
rely on it and create the cache directory ourselves in those build
jobs that read/write cached data (currently only the prove state).
In the following commit we'll start to cache additional data in every
build job, and will access the cache much earlier in the build
process.
Therefore move creating the cache directory to 'ci/lib-travisci.sh' to
make sure that it exists at the very beginning of every build job.

The leak_pending flag is so awkward to use that multiple comments had to
be added around each occurrence. We only use it for remembering the
commits whose marks we have to clear after checking if the old HEAD is
detached. This is easy, though: We need to do that for the old commit,
the new one -- and for all refs.
Don't bother tracking exactly which commits need their flags cleared,
just nuke all we have in-core. This change is safe because refs can
point at anything, so other program parts can't depend on any kept flags
anyway. And since all refs are loaded we have to basically deal with
all commits anyway, so performance should not be negatively impacted.

The leak_pending flag is so awkward to use that multiple comments had to
be added around each occurrence. We use it for remembering the
prerequisites for the bundle. That is easy, though: We have the
ref_list named "prerequisites" in the header for just that purpose.
Use this original list of prerequisites to check if all of them are
present and to clear their commit marks afterward. The two new loops
are intentionally kept similar to the first one in the function.
Calling parse_object() a second time is expected be quick and successful
in each case -- any errors should have been handled in the first round.

Pass the entries of the commit array directly to clear_commit_marks_1()
instead of adding them to a commit_list first. The function clears the
commit and any first parent without allocation; only higher numbered
parents are added to a list for later treatment. This change extends
that optimization to clear_commit_marks_many().

what that commit started by removing the BLK_SHA1 fallback setting so

Before 425a28e0a4 (diff-lib: allow ita entries treated as "not yet exist
in index" - 2016-10-24) there are never "new files" in the index, which
essentially disables rename detection because we only detect renames
when a new file appears in a diff pair.
After that commit, an i-t-a entry can appear as a new file in "git
diff-files". But the diff callback function in wt-status.c does not
handle this case and produces incorrect status output.
PS. The reader may notice that this patch adds a new xstrdup() but not
a free(). Yes we leak memory (the same for head_path). But wt_status
so far has been short lived, this leak should not matter in
practice.
