If there's already a remote-helper tracking ref, we can fetch the
SHA-1 to report proper push messages (as opposed to always reporting
[new branch]).
The remote-helper currently can specify the old SHA-1 to avoid this
problem, but there's no point in forcing all remote-helpers to be aware
of git commit ids; they should be able to be agnostic of them.

This allows a remote helper using the 'export' protocol to specify that
it supports signed tags, changing the handing from 'warn-strip' to
'verbatim'.

Currently, attempting to push a signed tag to a remote helper which uses
fast-export results in the remote helper failing because the default
fast-export action for signed tags is "abort". This is not helpful for
users because there is no way to pass additional arguments to
fast-export here, either from the remote helper or from the command
line.
In general, the signature will be invalidated by whatever transformation
a remote helper performs on a tag to push it to a repository in a
different format so the correct behaviour is to strip the tag. Doing
this silently may surprise people, so use "warn-strip" to issue a
warning when a signed tag is encountered.

When an object has already been exported (and thus is in the marks) it's
flagged as SHOWN, so it will not be exported again, even if in a later
time it's exported through a different ref.
We don't need the object to be exported again, but we want the ref
updated, which doesn't happen.
Since we can't know if a ref was exported or not, let's just assume that
if the commit was marked (flags & SHOWN), the user still wants the ref
updated.
IOW: If it's specified in the command line, it will get updated,
regardless of whether or not the object was marked.
So:
% git branch test master
% git fast-export $mark_flags master
% git fast-export $mark_flags test
Would export 'test' properly.
Additionally, this fixes issues with remote helpers; now they can push
refs whose objects have already been exported, and a few other issues as
well. Update the tests accordingly.

They have been marked as UNINTERESTING for a reason, lets respect
that. Currently the first ref is handled properly, but not the
rest. Assuming that all the refs point at the same commit in the
following example:
% git fast-export master ^uninteresting ^foo ^bar
reset refs/heads/bar
from :0
reset refs/heads/foo
from :0
reset refs/heads/uninteresting
from :0
% git fast-export ^uninteresting ^foo ^bar master
reset refs/heads/master
from :0
reset refs/heads/bar
from :0
reset refs/heads/foo
from :0
Clearly this is wrong; the negative refs should be ignored.
After this patch:
% git fast-export ^uninteresting ^foo ^bar master
# nothing
% git fast-export master ^uninteresting ^foo ^bar
# nothing
And even more, it would only happen if the ref is pointing to exactly
the same commit, but not otherwise:
% git fast-export ^next next
reset refs/heads/next
from :0
% git fast-export ^next next^{commit}
# nothing
% git fast-export ^next next~0
# nothing
% git fast-export ^next next~1
# nothing
% git fast-export ^next next~2
# nothing
The reason this happens is that before traversing the commits,
fast-export checks if any of the refs point to the same object, and any
duplicated ref gets added to a list in order to issue 'reset' commands
after the traversing. Unfortunately, it's not even checking if the
commit is flagged as UNINTERESTING. The fix of course, is to check it.
However, in order to do it properly we need to get the UNINTERESTING
flag from the command line, not from the commit object, because
"^foo bar" will mark the commit 'bar' uninteresting if foo and bar
points at the same commit. rev_cmdline_info, which was introduced
exactly to handle this situation, contains all the information we
need for get_tags_and_duplicates(), plus the ref flag. This way the
rest of the positive refs will remain untouched; it's only the
negative ones that change in behavior.

This only makes sense for the python remote helpers framework. The tests
don't exercise any feature of transport helper. Remove them.

Exercising the python remote helper framework is for another tool and
another test. This is about testing the remote-helper interface.
It's way simpler, it exercises the same features of remote helpers, it's
easy to read and understand, and it doesn't depend on python.
For now let's just copy the old remote-helpers test script, although
some of those tests don't make sense. In addition, this script would be
able to test other features not currently being tested.
