After packaging references, the folders containing these references are
not deleted. In a busy repository, this causes operations to slow down
as traversing the references tree becomes longer.
Delete empty reference folders after the loose references have been
packed.
To avoid deleting a folder that was just created by another concurrent
operation, only delete folders that were not modified in the last 30
seconds.

It is convenient for TestRepository to return fully parsed
objects from its commit()/tree()/blob() methods, so that test
code doesn't have to remember to parse them before making
assertions about them.
Update TestRepostiory to return fully parsed objects.
Adjust the tests that are affected by this change in behavior.

In a new RevWalk, if the first object parsed is one of the
shallow commits, the following happens:
1) RevCommit.parseCanonical() is called on a new "r1" RevCommit.
2) RevCommit.parseCanonical() immediately calls
RevWalk.initializeShallowCommits().
3) RevWalk.initializeShallowCommits() calls lookupCommit(id),
creating and adding a new "r2" version of this same object and
marking its parents empty.
4) RevCommit.parseCanonical() initializes the "r1" RevCommit's
fields, including the parents.
5) RevCommit.parseCanonical()'s caller uses the "r1" commit that
has parents, losing the fact that it is a shallow commit.
This change passes the current RevCommit as an argument to
RevWalk.initializeShallowCommits() so that method can set its
parents empty rather than creating the duplicate "r2" commit.

The previous algorithm selected commits by creating bitmaps at
each branch tip, doing a revwalk to populate each bitmap, and
looping in this way:
1) Select the remaining branch with the most commits (the branch
whose bitmap has the highest cardinality)
2) Select well-spaced bitmaps in that branch
3) Remove commits in the selected branch from the remaining
branch-tip bitmaps
4) Repeat at #1
This algorithm gave good commit selection on all branches but
a more uniform selection on "important" branches, where branch
length is the proxy for "important". However the algorithm
required N bitmaps of size M solely for the purpose of commit
selection, where N is the number of branch tips in the primary
GC pack, and M is the number of objects in the pack.
This new algorithm uses branch modification date as the proxy for
"important" branches, replacing the N*M memory allocation with a
single M-sized bitmap and N revwalks from new branch tips to
shared history (which will be short when there is a lot of shared
history).
GcCommitSelectionTest.testDistributionOnMultipleBranches verifies
that this algorithm still yields good coverage on all branches.

This change fixes the issue [1]. Before this fix, a merge involving
the caching of consecutive yet similar filenames with Norwegian
characters [2] used to throw an IllegalStateException: Duplicate
stages not allowed. This was caused by inaccurate decoding of the
filenames, using string values assuming default encoding. In the
toString method of DirCacheEntry, used before through getPathString,
UTF-8 encoding is used, but the end result becomes default encoding,
through Object's default toString usage. The special characters in
those two consecutive (particular) filenames [2] were becoming the
very same decoded /single character, lending consecutive -but then
identical- filenames. Thus the perceived duplicate 0-staging of the
file(s).
Replace getPathString usage with getRawPath for this specific case,
or use byte array representations of cached entries instead of string.
Adding a test for this change is not possible, as there is no known
way to change the default encoding for filenames such as [2] (e.g.).
JGitTestUtil does write file contents through UTF-8, but encoding like
so does not apply to the actual file name. Hence there is no way to
create files with names properly made of special characters such as
[2]'s. And the test that is necessary for this case assumes such
Norwegian (or similar characters) filenames. Changing the default
locale programmatically in a test has no effect either. And changing
the LANG value passed to the JVM is only possible upon starting it.

If I run

git init --bare
git remote add origin https://go.googlesource.com/proposal

git fetch --unshallow
then I expect to have a full history, just as though I had fetched
without --depth in the first place. Instead, it reports success
but does not fetch enough objects:

The false success indicates problems in the client and the server.
Git 2.18-rc2 (the client) ought to have been more defensive, noticing
the incomplete history. The greater error is in JGit (the server),
which neglects to send the objects requested.
When serving protocol v0 requests, JGit sends the correct objects by
taking unshallowCommits into account when generating the pack to send
to the client. Do the same in the protocol v2 code path. I forgot to
do this in v5.0.0.201806050710-rc3~6 (Teach UploadPack shallow fetch
in protocol v2, 2018-03-15).

Instead, do it when we return the first PlotCommit from next().
On a repository with many refs, getAllRefsByPeeledObjectId() can
take a while. Doing a late initialization simplifies the handling
of a PlotWalk.
EGit, for instance, creates and configures an instance, and then
does the real walk in a background job. With late initialization,
the potentially expensive getAllRefsByPeeledObjectId() also occurs
in that background job.

JGit now considers lightweight tags only if the --tags option is set
i.e. `git.describe().setAllTags(true)` has to be set, else the default
is now as in c git:
Only annotated tags are evaluated unless you pass true
equivalent to --tags (or --all) by the option setAllTags.
Hint: This (still) doesn't address any difference between c-git
`--all` and `!--all --tags` behavior;
perhaps this might be a follow up request
