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.

We block SIGINT and SIGQUIT while the editor runs so that
git is not killed accidentally by a stray "^C" meant for the
editor or its subprocesses. This works because most editors
ignore SIGINT.
However, some editor wrappers, like emacsclient, expect to
die due to ^C. We detect the signal death in the editor and
properly exit, but not before writing a useless error
message to stderr. Instead, let's notice when the editor was
killed by a terminal signal and just raise the signal on
ourselves. This skips the message and looks to our parent
like we received SIGINT ourselves.
The end effect is that if the user's editor ignores SIGINT,
we will, too. And if it does not, then we will behave as if
we did not ignore it. That should make all users happy.
Note that in the off chance that another part of git has
ignored SIGINT while calling launch_editor, we will still
properly detect and propagate the failed return code from
the editor (i.e., the worst case is that we generate the
useless error, not fail to notice the editor's death).

The user's editor likely catches SIGINT (ctrl-C). but if
the user spawns a command from the editor and uses ctrl-C to
kill that command, the SIGINT will likely also kill git
itself (depending on the editor, this can leave the terminal
in an unusable state).
Let's ignore it while the editor is running, and do the same
for SIGQUIT, which many editors also ignore. This matches
the behavior if we were to use system(3) instead of
run-command.

Pushes must already (by default) update to a commit-ish due to the fast-
forward check in set_ref_status_for_push(). But rejecting for not being
a fast-forward suggests the situation can be resolved with a merge.
Flag these updates (i.e., to a blob or a tree) as not forwardable so the
user is presented with more appropriate advice.
While updating *from* a tag object is potentially destructive, updating
*to* a tag is not. Additionally, a push to the refs/tags/ hierarchy is
already excluded from fast-forwarding, and refs/heads/ is protected from
anything but commit objects by a check in write_ref_sha1(). Thus
someone fast-forwarding to a tag is probably not doing so by accident.
Since updating to a tag is benign and unlikely to cause confusion, allow
it in case someone finds the behavior useful.

struct msg_data stored (ptr, len) of the data to be included in a
message, kept the character data NUL-terminated, etc., much like a
strbuf would do. So change it to use a struct strbuf. This makes
the code clearer and reduces copying a little bit.
A side effect of this change is that the memory for each message is
freed after it is used rather than leaked, though that detail is
unimportant given that imap-send is a top-level command.
By the way, there is a bunch of infrastructure in this file for
dealing with IMAP flags, although there is nothing in the code that
actually allows any flags to be set. If there is no plan to add
support for flags in the future, a bunch of code could be ripped out
and "struct msg_data" could be completely replaced with strbuf, but
that would be a separate topic.
