ref: check the full refname instead of basename
In "files-backend.c::files_fsck_refs_name", we validate the refname
format by using "check_refname_format" to check the basename of the
iterator with "REFNAME_ALLOW_ONELEVEL" flag.
However, this is a bad implementation. Although we doesn't allow a
single "@" in ".git" directory, we do allow "refs/heads/@". So, we will
report an error wrongly when there is a "refs/heads/@" ref by using one
level refname "@".
Because we just check one level refname, we either cannot check the
other parts of the full refname. And we will ignore the following
errors:
"refs/heads/ new-feature/test"
"refs/heads/~new-feature/test"
In order to fix the above problem, enhance "files_fsck_refs_name" to use
the full name for "check_refname_format". Then, replace the tests which
are related to "@" and add tests to exercise the above situations using
for loop to avoid repetition.
