Add an implementation for HttpConnection using Apache HttpClient
This change implements the http connection abstraction with the help of
org.apache.http.client.HttpClient. The default implementation used by
JGit is still the JDK HttpURLConnection. But now JGit users have the
possibility to switch completely to org.apache.httpclient. The reason
for this is that in certain (e.g. cloud) environments you are forced to
use the org.apache classes.

Previously all HTTP communication was done with the help of
java.net.HttpUrlConnection. In order to make JGit usable in environments
where the direct usage of such connections is not allowed but where the
environment provides other means to get network connections an
abstraction for connections is introduced. The idea is that new
implementations of this interface will be introduced which will not use
java.net.HttpUrlConnection but use e.g.
org.apache.client.http.HttpClient to provide network connections.
One example: certain cloud infrastructures don't allow that components
in the cloud communicate directly with HttpUrlConnection. Instead they
provide services where a component can ask for a connection (given a
symbolic name for the destination) and where the infrastructure returns
a preconfigured org.apache.http.client.HttpClient. In order to allow
JGit to be running in such environments we need the abstraction
introduced in this commit.

spurious MissingObjectExceptions at read time. If two threads are

no object and eventually consider tryAgain1(). If thread A is put
to sleep and this point and thread B also does not find the object,
loads the packs, when thread A wakes up its tryAgain1 would return
false and the thread never considers the packs.
Rework the internal API of ObjectDirectory to keep a handle on the
exact PackList that was iterated by thread A, allowing it to always
retry walking through the packs if the new PackList is different.
This had some ripple effect into the CachedObjectDirectory and
the shared FileObjectDatabase interface. The new code should be
slightly easier to follow, especially from the perspective of the
CachedObjectDirectory trying to minimize the number of open system

archive: Use an empty directory for submodules
When encountering a submodule entry, "jgit archive" tries to write its
content verbatim as an entry to the archive, which fails with a
JGitInternalException wrapping a MissingObjectException because the
submodule repository commits are typically not part of the
superproject.
When a subproject is available (for example because it has been
checked out as a subdirectory of a superproject worktree), it would be
nice to recurse into it and make one archive recording the state of
the entire project. Unfortunately sometimes the subproject is not
available or it can be hard to find (e.g., it can be on another
server). Even when some subprojects are available, "jgit archive"
should not produce different output for the same tree depending on
which subprojects it has easy access to, so there is no obvious good
default behavior that recurses without relying on access to all
subprojects.
Instead, replace each submodule entry with a placeholder empty
directory. "git archive" does the same.

Fix exception on conflicts with recursive merge
When there are conflicts with a recursive merge, the conflicting paths
are stored in unmergedPaths (field in ResolveMerger). Later, when the
MergeResult is constructed in MergeCommand, getBaseCommit is called,
which computes the merge base a second time.
In case of RecursiveMerger, getBaseCommit merges the multiple merge
bases into one. It does this not by creating a new ResolveMerger but
instead calling mergeTrees. The problem with mergeTrees is that at the
end, it checks if unmergedPaths is non-empty and returns false in that
case.
Because unmergedPaths was already non-empty because of the real merge,
it thinks that there were conflicts when computing the merge base again,
when there really were none.
This can be fixed by storing the base commit when computing it and then
returning that instead of computing it a second time.
Note that another possible fix would be to just use a new ResolveMerger
for merging the merge bases instead. This would also remove the need to
remember the old value of dircache, inCore and workingTreeIterator (see
RecursiveMerger#getBaseCommit).

This commit fixes this problem.
Still JGit behaves intentionally different than native git.
If HEAD contains a tree, and workingtree, Index and Merge contain a file
with same content ... then JGit allows a conflict free checkout of
Merge. Native git always complains that it doesn't want to overwrite
local changes. But there is no need to update the working tree because
Index and Merge are already equal.
