During object enumeration for the thin pack, very few objects come
out that are duplicated with the cached pack. Typically these are
only cases where a blob or tree was cherry-picked forward, got a
copy or rename, or was reverted... all relatively infrequent events.
Speed up pruning of the thin pack object list by combining the phase
with the object representation selection. Implementers should already
be offering to reuse the object from the cached pack if it is stored
there, at which point the implementation can perform a very fast type
of containment test using the cached pack's identity rather than yet
another index lookup. For the local disk case this is probably not a
big improvement, but it does help on the DHT implementation where the
two passes combined into one reduces latency.

Detaching HEAD didn't work in some corner checkout cases. If, for example,
HEAD is symbolic ref to refs/heads/master, refs/heads/master is ref to commit
c0ffee... then:
checkout c0ffee...
would leave the HEAD unchanged.
The same symptom occurs when checking out a remote tracking branch or a tag
that references the same commit as refs/heads/master.
In the above case, the RefUpdate class didn't have enough information to decide
if the update needed to detach symbolic ref because it dealt only with new/old
objectIDs. Therefore, this fix introduced the RefUpdate.detachingSymbolicRef
flag.

is mainly a wrapper around IndexDiff class. Better support for multiple

The RemoteSession interface operates like a simplified version of
java.lang.Runtime with a single exec method (and a disconnect
method). It returns a java.lang.Process, which should begin execution
immediately. Note that this greatly simplifies the interface for
running commands. There is no longer a connect method, and most
implementations will contain the bulk of their code inside
Process.exec, or a constructor called by Process.exec. (See the
revised implementations of JschSession and ExtSession.)
Implementations can now configure their connections properly without
either ignoring the proper use of the interface or trying to adhere
to an overly strict interface with odd rules about what methods are
called first. For example, Jsch needs to create the output stream
before executing, which it now does in the process constructor. These
changes should make it much easier to add alternate session
implementations in the future.

In order to distinguish cherry-pick failures caused by conflicts vs.
'abnormal failures' (e.g. due to unstaged changes or a dirty
worktree), a CherryPickResult class is introduced and returned by
CherryPickCommand.call() instead of a RevCommit. This new class is
similar to MergeResult and RebaseResult. The CherryPickResult contains
all necessary information, e.g. paths causing the cherry-pick (a merge
called within, respectively) to fail. This allows callers to better
react on failures.

Frequently enough I'm wondering how much of a pack is commits vs.
trees, and the total line doesn't really tell us this because its
a gross total from the pack. Computing the counts per object type
is simple during packing, as PackWriter already has everything in
memory broken up by object type. Its virtually free to get these
values and track them.

When fetching from a remote peer, consider all of the refs of any
alternate repository to be reachable locally, in addition to the refs
of the local repository. This mirrors the push protocol and may avoid
unnecessary object transfer when the local repository is empty, but
its alternate and the remote share a lot of common history.
Junio C Hamano recently proposed a similar change to C Git's fetch
client, in order to work around a performance bug I identified when
fetching between two repositories that actually shared the same
alternate repository on the local system.

If the remote peer replies with "ERR %s" instead of "ACK %s common" or
"NAK" during ancestor negotiation in the fetch-pack/upload-pack
protocol, treat that as an exception that aborts processing with the
error text as supplied by the remote system.
This matches behavior with "ERR %s" during the advertisements, which
is also a way for the remote to abort processing.
