This patch adds a new 'find-rev' command to git-svn that lets you easily
translate between SVN revision numbers and git tree-ish.

Many functions and operators in perl set $_, so its value cannot be relied upon
after calling arbitrary functions. The solution is simply to copy the value of
$_ into a local variable that will not get overwritten.

git only tracks the histories of full directories, not
that of individual files.  Sometimes, SVN users will
place[1] a regular file in the directory designated
for subdirectories of branches or tags.

When patches are merged from another git-svn managed branch,
they will have the git-svn-id: metadata line in them (generated
by git-format-patch).

When doing rebase or dcommit via git-svn, this would cause
git-svn to find the wrong upstream branch.  We now verify
that the commit is consistent with the value in the .rev_db
file.

We ignore errors if the path we're tracking did not exist for
a particular revision range, but we still print out warnings
telling the user about that.

As pointed out by Seth Falcon, this amounts to a lot of warnings
that could confuse and worry users.  I'm not entirely comfortable
completely silencing the warnings, but showing one warning per
path that we track should be reasonable.

When using do_switch:

When using do_update:

If we are run inside a subdirectory of a working tree, we'll
chdir to the top first before touching anything.  This also
prevents the accidental creation of .git directories inside
subdirectories since they need metadata.

This allows the user to run git-svn show-ignore on there
current HEAD without needing to remember which branch/ref they
branched from with -i.  Also, find_by_url should correctly
handle cases where the URL passed to it is not valid.
Signed-off-by: NEric Wong <normalperson@yhbt.net>

Since the options that affect the way metadata is handled in
git-svn, should be consistently set/unset throughout history
imported by git-svn; it makes sense to allow the user to set
certain options from the command-line that will write to the
config file when initially creating the repository.

Also, fix some formatting issues while we're updating
documentation.

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).

This is similar to useSvmProps, but far simpler in
implementation because svnsync retains a 1:1

This feature allows users to create repositories from alternate

Having it named as 'config' prevents us from tracking a
ref named 'config', which is a huge mistake.

On the non-technical side, the word 'config' implies that

This works similarly to 'svn update' or 'git pull' except that
it preserves linear history with 'git rebase' instead of 'git
merge' for ease of dcommit-ing with git-svn.

While we're at it, put the working_head_info() logic
into its own function and allow --fetch-all/--all for
dcommit and rebase (which will fetch all refs in the
current [svn-remote] instead of just the working one).

Note that the '-a' switch (short for --fetch-all/--all) has been
removed as it conflicts with the non-svn 'git fetch'

On newly-created repositories, 'refs/heads/master' does not
point to anything.  This can be confusing to new users; so we
update 'master' to point to the last imported ref after fetching
is done.

Once 'master' is valid; we assume HEAD points to it; and if
the repository is not bare, then checkout the files if the
working tree is clean and unused.

This allows users to use SVM (SVN::Mirror) to mirror a remote
repository to use dcommit to commit to the repository that SVM
was mirroring.  When dcommit is used in this manner, the automatic
fetch + rebase/reset does not happen; in which case the user will
have to manually invoke svm/svk, run 'git svn fetch', and finally
'git rebase'.

multi-fetch is deprecated, "fetch -a" is easier to type
By default, fetch will fetch everything from its default
