"git hash-object" now checks that the resulting object is well
formed with the same code as "git fsck".
* jk/hash-object-fsck:
fsck: do not assume NUL-termination of buffers
hash-object: use fsck for object checks
fsck: provide a function to fsck buffer without object struct
t: use hash-object --literally when created malformed objects
t7030: stop using invalid tag name
t1006: stop using 0-padded timestamps
t1007: modernize malformed object tests
