Instead of immediately printing ll-merge warnings to stderr, we save
them in our output strbuf. Besides allowing us to move these warnings
to a special file for --remerge-diff, this has two other benefits for
regular merges done by merge-ort:
* The deferral of messages ensures we can print all messages about
any given path together (merge-recursive was known to sometimes
intersperse messages about other paths, particularly when renames
were involved).
* The deferral of messages means we can avoid printing spurious
conflict messages when we just end up aborting due to local user
modifications in the way. (In contrast to merge-recursive.c which
prematurely checks for local modifications in the way via
unpack_trees() and gets the check wrong both in terms of false
positives and false negatives relative to renames, merge-ort does
not perform the local modifications in the way check until the
checkout() step after the full merge has been computed.)

When this option is specified, we remerge all (two parent) merge commits
and diff the actual merge commit to the automatically created version,
in order to show how users removed conflict markers, resolved the
different conflict versions, and potentially added new changes outside
of conflict regions in order to resolve semantic merge problems (or,
possibly, just to hide other random changes).
This capability works by creating a temporary object directory and
marking it as the primary object store. This makes it so that any blobs
or trees created during the automatic merge are easily removable
afterwards by just deleting all objects from the temporary object
directory.
There are a few ways that this implementation is suboptimal:
* `log --remerge-diff` becomes slow, because the temporary object
directory can fill with many loose objects while running
* the log output can be muddied with misplaced "warning: cannot merge
binary files" messages, since ll-merge.c unconditionally writes those
messages to stderr while running instead of allowing callers to
manage them.
* important conflict and warning messages are simply dropped; thus for
conflicts like modify/delete or rename/rename or file/directory which
are not representable with content conflict markers, there may be no
way for a user of --remerge-diff to know that there had been a
conflict which was resolved (and which possibly motivated other
changes in the merge commit).
* when fixing the previous issue, note that some unimportant conflict
and warning messages might start being included. We should instead
make sure these remain dropped.
Subsequent commits will address these issues.

"git fetch" without the "--update-head-ok" option ought to protect
a checked out branch from getting updated, to prevent the working

the branch that was checked out in the current worktree, which has
been updated.

Do a full ssh signing, find-principals and verify operation in the test
prereq's to make sure ssh-keygen works as expected. Only generating the
keys and verifying its presence is not sufficient in some situations.
One example was ssh-keygen creating unusable ssh keys in cygwin because
of unsafe default permissions for the key files. The other a broken
openssh 8.7 that segfaulted on any find-principals operation. This
extended prereq check avoids future test breakages in case ssh-keygen or
any environment behaviour changes.

If valid-before/after dates are configured for this signatures key in the
allowedSigners file then the verification should check if the key was valid at
the time the commit was made. This allows for graceful key rollover and
revoking keys without invalidating all previous commits.
This feature needs openssh > 8.8. Older ssh-keygen versions will simply
ignore this flag and use the current time.
Strictly speaking this feature is available in 8.7, but since 8.7 has a
bug that makes it unusable in another needed call we require 8.8.
Timestamp information is present on most invocations of check_signature.
However signer ident is not. We will need the signer email / name to be able
to implement "Trust on first use" functionality later.
Since the payload contains all necessary information we can parse it
from there. The caller only needs to provide us some info about the
payload by setting payload_type in the signature_check struct.
- Add payload_type field & enum and payload_timestamp to struct
signature_check
- Populate the timestamp when not already set if we know about the
payload type
- Pass -Overify-time={payload_timestamp} in the users timezone to all
ssh-keygen verification calls
- Set the payload type when verifying commits
- Add tests for expired, not yet valid and keys having a commit date
outside of key validity as well as within
