If the thread reading a pack file is interrupted don't invalidate that
pack file.
This could happen when Gerrit invoked JGit for computing a diff in one
thread and waited for the call to finish from another thread, with a
timeout. When the timeout was reached the "diff" thread was interrupted.
If it happened to be in an IO operation, reading a pack file, an
InterruptedIOException was thrown and the pack file was marked as
invalid and removed from the pack list.
Invalidating the pack in that case could cause the project disappearing in
Gerrit as discussed in [1] and [2].

Now that d7a4473 removed the gitprefix property, we did not have a way to
specify the path to the Git system config file in case
discoverGitSystemConfig() fails. Fix that by introducing a member variable
that caches the result of discoverGitSystemConfig() as well as a setter
method to overwrite the content of that variable.

Commit d3348e introduced few errors in Eclipse.
This commit cleans up the new API:
- fixes API error in RepoCommand after moving IncludedFileReader type
- fixes unused imports in RepoCommand & RepoCommandTest
- fix javadoc errors in ManifestParser & RepoProject
- makes three (implicitly final) fields in ManifestParser final.

The repo xml manifest parser used in RepoCommand could also be useful for
others, so refactor to make it public.
Also this breaks backward compatibility slightly.

The only purpose of the gitprefix logic was to determine the path to the
system-wide config file. This is now done by discoverGitSystemConfig()
independent of the gitprefix, so get rid of this unused code.

- the default ObjectFilter is ALL
- ObjectFilter affects nextObject() and not next()
- omitting a tree implies omitting its subtrees
- a blob or tree reached by another path is still returned
- ObjectFilter can be mixed with RevFilter

git-core has supported this for a long time; allowing clients to
avoid progress messages from the server if they are dumping to a
pipe instead of a tty.
Avoid the two progress monitors going on side-band and expose
isQuiet() method to allow hooks to also reduce their output if
this is sensible for them.

In 77030a5e, AutoClosable was implemented on classes that use release().
This caused a resource leak because the ObjectReader.close method was
not calling the now deprecated release method, which is the method that
sub classes implements to release resources.

The Java GC doesn't always clear these before running out of memory
and failing allocations. In practice OpenJDK 7 is leaving these live,
removing any advantage of the SoftReference to attempt to shed memory
when the GC is unable to continue allocating.
Instead follow the pattern of the DfsBlockCache and use hard refs
to the object data. Require applications to configure the cache
size more accurately given expected memory usage.

The LRU chain management code was broken leading to situations where
the chain was incomplete. This prevented the cache from removing
items when it exceeded its memory target, causing a leak.
One case was repeated hit on the head of the chain. moveToHead(e)
was invoked linking the head back to itself in a cycle orphaning
the rest of the table.
Add some unit tests to cover this and a few other paths.

As Chris pointed out change I822721c76c64e614f87a080ced2457941f53adcd
slowed down merge since ANY_DIFF filter is much less efficient than the
manual detection of diffs done in ResolveMerger.processEntry() since it
avoids unnecessary filesystem calls using the git index. Hence only set
the ANY_DIFF filter on bare repositories which don't have a working tree
to scan.
To test performance I used the setup described in Chris' comment on
change I822721c76c64e614f87a080ced2457941f53adcd and modified
ResolveMerger.mergeTrees() to not add the working tree in order to
simulate merging in a bare repository.
At least on Mac I couldn't detect a speedup, with and without the
ANY_DIFF filter merge test takes an average 0.67sec.

Avoid always calling `sh -c umask` on startup, instead deferring
the invocation until the first time a working tree file needs to
use the execute bit. This allows servers using bare repos to avoid
a costly fork+exec for a value that is never used.
Store the umask as an int instead of two Boolean. This is slightly
smaller memory (one int vs. two references) and makes it easier for
an application to force setting the umask to a value that overrides
whatever the shell told JGit.
Simplify the code to bail by returning early when canExecute is
false, which is the common case for working tree files.

Applications that use a commit message once and do not
need it again can free the body to save memory. Expose
the disposeBody() methods to support this and use it in
pgm.Log which only visits each commit once.

This was added a very long time ago to support the failed
DHT storage implementation. Since then no storage system
was able to make use of this API, but it pollutes internals
of the walkers.
Kill the API on ObjectReader and drop the invocations from
the walker code.

Previously using an ObjectWalk meant uninteresting commits may keep
their commit message buffers in memory just in case they were found to
be on the boundary and were output as UNINTERESTING for the caller.
This was incorrect inside StartGenerator. ObjectWalk hides these
internal UNINTERESTING cases from its caller unless RevSort.BOUNDARY
was explicitly set, and its false by default. Callers never see one
of these saved uninteresting commits.
Change the test to allow early dispose unless the application has
explicitly asked for RevSort.BOUNDARY. This allows uninteresting
commit buffers to be discarded and garbage collected in ObjectWalks
when the caller will never be given the RevCommit.
