Currently we're buffering the inflated bitmap entry in
BasePackBitmapIndex to optimize running time. However, this will use
lots of memory during the creation of the pack bitmap index file.
And change 161456, which rewrote the entire getBitmap method, increased
the fetch latency significantly.
This commit introduces getBitmapWithoutCaching method which is used in
the pack bitmap index file creation only and aims to save memory during
garbage collection and not increase fetch latency.

We can either
- try moving the file and, in case the target directory doesn't exist,
handle the NoSuchFileException this raises to create the target
directory
- or we always first test if the target directory exists and create it
in case it is missing
On my Mac this yields
Benchmark Mode Cnt Score Error Units
FileMoveBenchmark.moveFileToExistingDir avgt 5 196.490 ± 15.194 us/op
FileMoveBenchmark.moveFileToExistingDirExists avgt 5 223.217 ± 54.816 us/op
FileMoveBenchmark.moveFileToMissingDir avgt 5 332.169 ± 43.871 us/op
FileMoveBenchmark.moveFileToMissingDirExists avgt 5 303.815 ± 137.568 us/op
This means if the target directory of the move already exists the
first strategy is faster by around 25 us/op otherwise the second one
is faster by around 30 us/op. Which one is favorable depends on the
average probability that the target directory exists in real world
scenarios.

The current mechanism for updating the unpack error handler requires
that the error handler is replaced entirely, including communicating
the error to the user. Adding a getter means that delegating
implementations can be constructed so that the error can be processed
before sending to the user, for example for logging.

If a hunk does not apply at the position stated in the hunk header
try to determine its position using the old lines (context and
deleted lines).
This is still a far cry from a full git apply: it doesn't do binary
patches, it doesn't handle git's whitespace options, and it's perhaps
not the fastest on big patches. C git hashes the lines and uses these
hashes to speed up matching hunks (and to do its whitespace magic).

BouncyCastle supports reading GPG keys without passphrase since 1.62.
Handle this in JGit, too, and don't prompt for a passphrase unless
it's necessary.
Make two passes over the private key files, a first pass without
passphrase provider. If that succeeds it has managed to read a
matching key without passphrase. Otherwise, ask the user for
the passphrase and make a second pass over the key files.
BouncyCastle 1.65 still has no method to get the GPG "key grip" from
a given public key, so JGit still cannot determine the correct file
to read up front. (The file name is the key grip as 40 hex digits,
upper case, with extension ".key").

On the first attempt to move the temp file, NoSuchFileException can
be raised if the destination folder does not exist. Instead of handling
this implicitly in the catch of IOException and then continuing to
create the destination folder and try again, explicitly catch it and
create the destination folder. If any other IOException occurs, treat
it as an unexpected error and return FAILURE.
Subsequently, on the second attempt to move the temp file, if ANY kind
of IOException occurs, also consider this an unexpected error and
return FAILURE.
In both catch blocks for IOException, add logging at ERROR level.

As discussed in the bug, jgit should not include a logging
implementation, and instead rely on the product containing jgit to
configure the logging.
We have recently run into the situation, that installing egit in a (non
eclipse.org) RCP application breaks all the logging due to incompatible
logging implementations. Removal of the jgit logging implementation
should fix this.
Following further changes have been done for jgit command line:
* added log4j.properties to binary build of jgit.pgm. That file existed
in the git repository, but was not included in the eclipse binary build.
(maybe it is in the bazel build)
* removed apache.commons.logging package import from jgit.pgm. That
import is not used, and makes the logging even more confusing.

Motivation: JSch serves as 'default' implementations of the SSH
transport. If a client application does not use it then there is no need
to pull in this dependency.
Move the classes depending on JSch to an OSGi fragment extending the
org.eclipse.jgit bundle and keep them in the same package as before
since moving them to another package would break API. Defer moving them
to a separate package to the next major release.
Add a new feature org.eclipse.jgit.ssh.jsch feature to enable
installation. With that users can now decide which of the ssh client
integrations (JCraft JSch or Apache Mina SSHD) they want to install.
We will remove the JCraft JSch integration in a later step due to the
reasons discussed in bug 520927.

Motivation: BouncyCastle serves as 'default' implementation of
the GPG Signer. If a client application does not use it there is no need
to pull in this dependency, especially since BouncyCastle is a large
library.
Move the classes depending on BouncyCastle to an OSGi fragment extending
the org.eclipse.jgit bundle. They are moved to a distinct internal
package in order to avoid split packages. This doesn't break public API
since these classes were already in an internal package before this
change.
Add a new feature org.eclipse.jgit.gpg.bc to enable installation. With
that users can now decide if they want to install it.
Attempts to sign a commit if org.eclipse.jgit.gpg.bc isn't available
will result in ServiceUnavailableException being thrown.

If the determination of the user home directory produces a Java File
object with an invalid path, spurious exceptions may occur at the
most inopportune moments anytime later. In the case in the linked bug
report, start-up of EGit failed, leading to numerous user-visible
problems in Eclipse.
So validate the return value of FS.userHomeImpl(). If converting that
File to a Path throws an exception, log the problem and fall back to
Java system property user.home. If that also is not valid, use null.
(A null user home directory is allowed by FS, and calling in Java
new File(null, "some_string") is fine and produces a File relative
to the current working directory.)
