LargePackedWholeObject: Do not reuse released inflater
LargePackedWholeObject.openStream produces a stream that allows
reading a large object. This stream holds a DfsReader that takes care
of caching delta bases etc and in particular holds zlib Inflater for
use while reading the each delta in the packfile.
At DfsReader creation time, the Inflater is acquired from a global
InflaterCache to avoid initialization overhead in case there is an
existing Inflater available for reuse. When done with the Inflater,
the DfsReader is responsible for returning it to the cache for reuse.
The DfsReader is AutoClosable to remind the caller to close it and
release the Inflater when finished with it.

this function returns, PackInputStream owns the DfsReader and is
already going to release it. Worse, the returned InflaterInputStream
holds a reference to the DfsReader's inflater, making releasing the
DfsReader not only unnecessary but unsafe.
The Inflater gets released into the InflaterCache's pool, to be
acquired by another caller that uses it concurrently with the
InflaterInputStream. This results in errors, such as

Significantly speed up FileTreeIterator on Windows
Getting attributes of files on Windows is an expensive operation.
Windows stores file attributes in the directory, so they are
basically available "for free" when a directory is listed. The
implementation of Java's Files.walkFileTree() takes advantage of
that (at least in the OpenJDK implementation for Windows) and
provides the attributes from the directory to a FileVisitor.
Using Files.walkFileTree() with a maximum depth of 1 is thus a
good approach on Windows to get both the file names and the
attributes in one go.
In my tests, this gives a significant speed-up of FileTreeIterator
over the "normal" way: using File.listFiles() and then reading the
attributes of each file individually. The speed-up is hard to
quantify exactly, but in my tests I've observed consistently 30-40%
for staging 500 files one after another, each individually, and up
to 50% for individual TreeWalks with a FileTreeIterator.
On Unix, this technique is detrimental. Unix stores file attributes
differently, and getting attributes of individual files is not costly.
On Unix, the old way of doing a listFiles() and getting individual
attributes (both native operations) is about three times faster than
using walkFileTree, which is implemented in Java.
Therefore, move the operation to FS/FS_Win32 and call it from
FileTreeIterator, so that we can have different implementations
depending on the file system.
A little performance test program is included as a JUnit test (to be
run manually).
While this does speed up things on Windows, it doesn't solve the basic
problem of bug 532300: the iterator always gets the full directory
listing and the attributes of all files, and the more files there are
the longer that takes.
