If a command is stopped by throwing a Die exception since a generic
exception was caught this exception contains additional information
which is not available in the error message. Hence chain it to the Die
exception in order to allow printing a complete stacktrace including
causes to the error stream of the JGit command line by adding option
--show-stack-trace, e.g.
$ jgit --show-stack-trace commit -m "test"

As explained in 'The "Double-Checked Locking is Broken"
Declaration'[*], Java's memory model does not support double-checked
locking:
class LazyReadableChannel {
private ReachableChannel rc = null;
public ReadableChannel get() {
if (rc == null) {
synchronized (this) {
if (rc == null) {
rc = new ReadableChannel();
}
}
}
return rc;
}
}
With JDK 5 and newer, there is a formal memory model that ensures this
works if "rc" is volatile, but it is still not thread-safe without
that.
Fortunately, this ReadableChannelSupplier is never passed between
threads, so it does not need to be thread-safe. Simplify by removing
the synchronization.

Currently, unit tests need to either close the Repository underlying a
TestRepository manually, or not close it at all. Both are error prone.
The TestRepository holds a reference to 4 AutoCloseable objects:
Repository, ObjectInserter, Git, and RevWalk. The last two can escape
the TestRepository scope, so they are not closed when TestRepository is
closed.

Opening a readable channel can be expensive and the number of channels
can be limited in DFS. Ensure that caller of
BlockBasedFile.readOneBlock() is responsible for opening and closing
the file, and that the ReadableChannel is reused in the request. As a side
effect, this makes the code easier to read, with better use of
try-with-resources.
The downside is that this means a readable channel is always opened, even
when the entire pack is already available for copying from cache. This
should be an acceptable cost: it's rare enough not to overload the server
and from a client latency perspective, the latency cost is in the noise
relative to the data transfer cost involved in a clone. If this turns out
to be a problem in practice, we can reintroduce that optimization in a
followup change.

We see the same index being loaded by multiple threads. Each is
hundreds of MB and takes several seconds to load, causing server to
run out of memory. This change introduces a lock to avoid these
duplicate works. It uses a new set of locks similar in implementation
to the loadLocks for getOrLoad of blocks. The locks are kept separate
to prevent long-running index loading from blocking out fast block
loading. The cache instance can be configured with a consumer to
monitor the wait time of the new locks.

CheckoutCommand had a setForce() method. But this didn't correspond
to native git's 'git checkout -f' option. Deprecate the old setForce()
method and move its implementation to a new method setForceRefUpdate()
and use it to implement the -B option in the CLI class Checkout.
Add a setForced() method and use it to fix the associated '-f' option of
the CLI Checkout class to behave like native git's 'git checkout -f'
which overwrites dirty worktree files during checkout.
This is still not fully matching native git's behavior: updating
additionally dirty index entries is not done yet.

Swallowing intermittent errors and trying to recover from them
makes JGit's behavior hard to predict and difficult to debug.
Propagate the errors instead. This doesn't violate JGit's usual
backward compatibility promise for clients because in these
contexts an IOException indicates either repository corruption or
a true I/O error. Let's consider these cases one at a time.
In the case of repository corruption, falling back e.g. to an empty
set of refs or a missing ref will not serve a caller well. The
fallback does not indicate the nature of the corruption, so they are
not in a good place to recover from the error. This is analogous to
Git, which attempts to provide sufficient support to recover from
corruption (by ensuring commands like "git branch -D" cope with
corruption) but little else.
In the case of an I/O error, the best we can do is to propagate the
error so that the user sees a dialog and has an opportunity to try
again. As in the corruption case, the fallback behavior does not
provide enough information for a caller to rely on the current error
handling, and callers such as EGit already need to be able to handle
runtime exceptions.
To be conservative, keep the existing behavior for the deprecated
Repository#peel method. In this example, the fallback behavior is to
return an unpeeled ref, which is distinguishable from the ref not
existing and should thus at least be possible to debug.

A checkout done directly after cloning (the "initial
checkout") has a different semantic as a default
checkout. That is defined in the documentation of
"git read-tree" [1]. JGit was detecting that it is
doing an initial checkout differently from native
git: jgit used to check that the index is empty
but native git required that the index file does
not exist [2]. Teach JGit to behave like native
git.

Using findRef instead of getRef makes it clearer that the caller wants
to search for the ref in the search path, instead of looking for a ref
that exactly matches the input.
This change introduces the new findRef method and deprecates getRef.
It updates Repository#findRef to use the new method, ensuring some
test coverage. Other callers will be updated in followup changes.
A nice side effect of introducing the new findRef method is that it is
final and based on firstExactRef, so implementers can focus on
implementing the latter efficiently and do not have to carefully write
custom path search code respecting SEARCH_PATH.

Override exactRef(String...) and firstExactRef(String...) with
implementations specific to FileRepository.
The specialized implementations are similar to the generic ones from
RefDatabase, but because these use readRef directly instead of
exactRef, they only need to call fireRefsChanged once.
This will allow replacing RefDirectory#getRef with a generic
implementation that uses firstExactRef without hurting performance.
