When a loose tree or commit is read by fsck (or any git
program), unpack_sha1_rest() checks whether there is extra
cruft at the end of the object file, after the zlib data.
Blobs that are streamed, however, do not have this check.
For normal git operations, it's not a big deal. We know the
sha1 and size checked out, so we have the object bytes we
wanted. The trailing garbage doesn't affect what we're
trying to do.
But since the point of fsck is to find corruption or other
problems, it should be more thorough. This patch teaches its
loose-sha1 reader to detect extra bytes after the zlib
stream and complain.

When we iterate over the list of loose objects to check, we
get the actual path of each object. But we then throw it
away and pass just the sha1 to fsck_sha1(), which will do a
fresh lookup. Usually it would find the same object, but it
may not if an object exists both as a loose and a packed
object. We may end up checking the packed object twice, and
never look at the loose one.
In practice this isn't too terrible, because if fsck doesn't
complain, it means you have at least one good copy. But
since the point of fsck is to look for corruption, we should
be thorough.
The new read_loose_object() interface can help us get the
data from disk, and then we replace parse_object() with
parse_object_buffer(). As a bonus, our error messages now
mention the path to a corrupted object, which should make it
easier to track down errors when they do happen.

It's surprisingly hard to ask the sha1_file code to open a
_specific_ incarnation of a loose object. Most of the
functions take a sha1, and loop over the various object
types (packed versus loose) and locations (local versus
alternates) at a low level.
However, some tools like fsck need to look at a specific
file. This patch gives them a function they can use to open
the loose object at a given path.
The implementation unfortunately ends up repeating bits of
related functions, but there's not a good way around it
without some major refactoring of the whole sha1_file stack.
We need to mmap the specific file, then partially read the
zlib stream to know whether we're streaming or not, and then
finally either stream it or copy the data to a buffer.
We can do that by assembling some of the more arcane
internal sha1_file functions, but we end up having to
essentially reimplement unpack_sha1_file(), along with the
streaming bits of check_sha1_signature().
Still, most of the ugliness is contained in the new
function, and the interface is clean enough that it may be
reusable (though it seems unlikely anything but git-fsck
would care about opening a specific file).

The code paths in fsck for packed and loose objects are
quite different, and it is not immediately obvious that the
packed case behaves well. In particular:
1. The fsck_loose() function always returns "0" to tell the
iterator to keep checking more objects. Whereas
fsck_obj_buffer() (which handles packed objects)
returns -1. This is OK, because the callback machinery
for verify_pack() does not stop when it sees a non-zero
return.
2. The fsck_loose() function sets the ERROR_OBJECT bit
when fsck_obj() fails, whereas fsck_obj_buffer() sets it
only when it sees a corrupt object. This turns out not
to matter. We don't actually do anything with this bit
except exit the program with a non-zero code, and that
is handled already by the non-zero return from the
function.
So there are no bugs here, but it was certainly confusing to
me. And we do not test either of the properties in t1450
(neither that a non-corruption error will caused a non-zero
exit for a packed object, nor that we keep going after
seeing the first error). Let's test both of those
conditions, so that we'll notice if any of those assumptions
becomes invalid.

When we fail to open a corrupt loose object, we report an
error and mention the filename via sha1_file_name().
However, that function will always give us a path in the
local repository, whereas the corrupt object may have come
from an alternate. The result is a very misleading error
message.
Teach the open_sha1_file() and stat_sha1_file() helpers to
pass back the path they found, so that we can report it
correctly.
Note that the pointers we return go to static storage (e.g.,
from sha1_file_name()), which is slightly dangerous.
However, these helpers are static local helpers, and the
names are used for immediately generating error messages.
The simplicity is an acceptable tradeoff for the danger.

Commit 90cf590f5 (fsck: optionally show more helpful info
for broken links, 2016-07-17) added a remove_loose_object()
helper, but we already had a remove_object() helper that did
the same thing. Let's combine these into one.
The implementations had a few subtle differences, so I've
tried to take the best of both:
- the original used "sed", but the newer version avoids
spawning an extra process
- the original processed "$*", which was nonsense, as it
assumed only a single sha1. Use "$1" to make that more
clear.
- the newer version ran an extra rev-parse, but it was not
necessary; it's sole caller already converted the
argument into a raw sha1
- the original used "rm -f", whereas the new one uses
"rm". The latter is better because it may notice a bug
or other unexpected failure in the test. (The original
does check that the object exists before we remove it,
which is good, but that's a subset of the possible
unexpected conditions).
