During my development of Id7721cc5b7ea650e77c2db47042715487983cae6, I
have found this test to be flaky when run by CI. As a speculative fix,
mark this test as @Ignore so it won't be run.

The changes I1db6fcf414b and I634b92877f added tests which were failing
with errors [1] and [2] with "bazel test //...". This was not caught
because we don't have CI running with bazel. Fix bazel build file so
that these errors are no longer thrown when run with bazel.

Change-Id: I5e13d5b5414aef97e518898166bfa166c692e60f
Move this test to another class and skip it when running tests with
bazel since the bazel test runner does not allow to create files in the
home directory.
FS#userHome retrieves the home directory on the first call and caches it
for subsequent calls to avoid overhead in case path translation is
required (currently on cygwin). This prevents that the test can mock the
home directory using MockSystemReader like SshTestHarness does.

The code is not violation free, so demote the severity of these bug
patterns to warning:
o DefaultCharset
o FutureReturnValueIgnored
o UnusedException

Always parse RevTags including their body before getting their object
to ensure that non-cached objects are handled correctly when traversing
a tag chain. An NPE in UploadPack#addTagChain will occur on a depth=1
fetch of a branch containing a tag chain and the ref to one of the
middle tags in the chain is deleted.

We found, when analysing an incident where Gerrit's gc runner thread got
stuck, that we can end up in an infinite loop in
ObjectDirectory#openPackedObject which tries to rescan the pack
list and starts over trying to open a packed object in an unconfined
loop if it catches a PackMismatchException.
Here the relevant part of a thread dump we created while the gc runner
was stuck:

The code in ObjectDirectory#openPackedObject [1] apparently assumes that
this is caused by a transient problem which it can resume from by
retrying. We use `core.trustFolderStat = false` on this server since it
uses NFS. The incident we had showed that we can enter into an infinite
loop here if there is a permanent mismatch between a pack file and its
corresponding pack index. I am not yet sure how this can happen.
Break the infinite loop by limiting the number of attempts rescanning
the pack list to 5 retries. When we exceed this threshold set the type
of the PackMismatchException to permanent and rethrow it which breaks
the infinite loop.
Also apply the same limit in #getPackedObjectSize
and #selectObjectRepresentation where we use similar retry loops.

Before this change, attempting to use the jgit Amazon S3 transport with an S3-compatible service that requires https (for example, Backblaze B2) results in an error:
$ jgit push b2
fatal: amazon-s3://metadaddy-jgit/repos/test/objects: error in packed-refs
This change adds a "protocol" property to the Amazon S3 transport configuration, defaulting to http, and uses that value when constructing the URL for the S3 service.
Example configuration for Backblaze B2:
accesskey: <Your B2 Application Key>
secretkey: <Your B2 Application Key Id>
acl: private
protocol: https
domain: s3.us-west-004.backblazeb2.com
region: us-west-004

A commit A can reach a commit B only if the generation number of A is
strictly larger than the generation number of B. This condition allows
significantly short-circuiting commit-graph walks.
On a copy of the Linux repository where HEAD is contained in v6.3-rc4
but no earlier tag, the command 'git tag --contains HEAD' of
ListTagCommand#call() had the following peformance improvement:
(excluded the startup time of the repo)
Before: 2649ms (core.commitgraph=true)
11909ms (core.commitgraph=false)

Loading of pack, bitmap and commit-graph copy the same code to adjust
the input stream buffering.
Extract to a common function. Besides reusing the code, the name hints
what it is doing.
This block aligment seems unnecessary as the reading is from storage
not dfs cache. The channel probably knows better. Left a TODO because
I don't know the original intention.
