There's no point in calculating an MD5 if we're not going to use
it. We'll also avoid the possibility of there being a bug in the
Perl MD5 library not being able to handle zero-sized files.
This is a followup to 20b3d206ac,
which allows us to track repositories that do not provide MD5
checksums.

I didn't have a chance to test the off-by-default minimize-url
stuff enough before, but it's quite broken for people passing
the --trunk/-T, --tags/-t, --branches/-b switches to "init" or
"clone" commands.
Additionally, follow-parent functionality seems broken when we're
not connected to the root of the repository.
Default behavior for "traditional" git-svn users who only track
one directory (without needing follow-parent) should be
reasonable, as those users started using things before
minimize-url functionality existed.
Behavior for users more used to the git-svnimport-like command
line will also benefit from a more-flexible command-line than
svnimport given the assumption they're working with
non-restrictive read permissions on the repository.
I hope to properly fix these bugs when I get a chance to in the
next week or so, but I would like to get this stopgap measure of
reverting to the old behavior as soon as possible.

When sorting directory names by depth (slash ("/") count) and
closing the deepest directories first (as the protocol
requires), we failed to put the root baton (with an empty string
as its key "") after top-level directories (which did not have
any slashes).
This resulted in svnserve being in a situation it couldn't
handle and caused a segmentation fault on the remote server.
This bug did not affect users of DAV and filesystem repositories.

For tracking branches and tags, git-svn prefers to connect
to the root of the repository or at least the level that
houses branches and tags as well as trunk. However, users
that are accustomed to tracking a single directory have
no use for this feature.
As pointed out by Junio, users may not have permissions to
connect to connect to a higher-level path in the repository.
While the current minimize_url() function detects lack of
permissions to certain paths _after_ successful logins, it
cannot effectively determine if it is trying to access a
login-only portion of a repo when the user expects to
connect to a part where anonymous access is allowed.
For people used to the git-svnimport switches of
--trunk, --tags, --branches, they'll already pass the
repository root (or root+subdirectory), so minimize URL
isn't of too much use to them, either.
For people *not* used to git-svnimport, git-svn also
supports:
git svn init --minimize-url \
--trunk http://repository-root/foo/trunk \
--branches http://repository-root/foo/branches \
--tags http://repository-root/foo/tags
And this is where the new --minimize-url command-line switch
comes in to allow for this behavior to continue working.
Some parts of SVN always seem to use it, even if the SVN::Ra
object we're using is no longer used and we've created a new one
in its place. It's also true that only one SVN::Ra connection
can exist at once... Using SVN::Pool->new_default when the
SVN::Ra object is created doesn't seem to help very much,
either...
Hopefully this fixes all segfault problems users have been
experiencing over the past few months.

This patch was originally intended to make the Perl GC more
sensitive to the SVN::Pool objects and not accidentally clean
them up when they shouldn't be (causing segfaults). That didn't
work, but this patch makes the code a bit cleaner regardless
Put our caches for get_dir and check_path calls directly into
the SVN::Ra object so they auto-expire when it is destroyed.
dirents returned by get_dir() no longer needs the pool object
stored persistently along with the cache data, as they'll be
converted to native Perl hash references.
Since calling rev_proplist repeatedly per-revision is no longer
needed in git-svn, we do not cache calls to it.

We no longer store usernames in URLs stored in git-svn-id lines
for dcommit, so we shouldn't rely on those URLs when connecting
to the remote repository to commit.
git-svn dcommit exports commits to Subversion, then imports them back
to git again, and last but not least rebases or resets HEAD to the
last of the new commits. I guess this rebasing is convenient when
using just git, but when the commits to be exported are managed by
StGIT, it's really annoying. So add an option to disable this
behavior. And document it, too!

After reading the leading contents from a symlink data obtained

the filehandle we read that 'link ' from. This was Ok with Perl
on modern Linux, but on Mac OS, the read in the parent process
slurped more than we asked for in stdio buffer, and the child

svm:mirror is not useful at all for us. Parts of the old unit
test were broken and based on my misunderstanding of the
svm:mirror property.
When we read svm:source; make sure we correctly handle the '!'
in it: it is used to separate the path of the repository root
from the virtual path within the repository. We don't need
to make that distinction, honestly!
We also ensure that subdirectories are also mirrored with the
correct URL if we're using useSvmProps.
We have a new test that uses dumped repo that was really
created using SVN::Mirror to avoid ambiguities and
mis-understandings about the svm: properties.
Note: trailing whitespace in the svm.dump file is unfortunately
a reality and required by SVN; so please ignore it when applying
this patch.
Also, ensure that the -R/--remote/--svn-remote flag is always
in effect if explicitly passed via the command-line. This
allows us to track logically different mirrors sharing the
same URL (probably common with SVN::Mirror/SVK users).
