clone: narrow success tests on HEAD-less remotes

2022-09-19T09:07:16+00:00

Only allow the remote default branch checking to fail when the remote
default branch doesn't exist (`git_remote__default_branch` returns
`GIT_ENOTFOUND`). If there was any other type of error - for example, an
allocation failure - we should not swallow that and continue to fail.

This allows us to support the case when a remote has not advertised a
HEAD -- this is possible, for example, when the remote has constrained
the caller to a particular namespace. But other remote failures remain
as failures.

Don't fail the whole clone if you can't find a default branch

In commit 6bb358786 ("clone: set refs/remotes/origin/HEAD to default
branch when branch is specified, attempt 2") libgit2 was changed to set
the default remote branch when one was copied.

But it makes update_head_to_branch() return an error if the origin
doesn't even *have* a HEAD in the first place, since
git_remote_default_branch() will fail.

That's entirely wrong, and means that you cannot do "git_clone()" of a
particular branch on a remote repository when that remote doesn't have a
default branch at all.

So don't set the error code.
