retrieve_device returns the file device for a given path (so that we can detect device change while walking through parent directories).
abspath returns a canonicalized path, symbolic link free.
retrieive_ceiling_directories_offset returns the biggest path offset that path match in the ceiling directory list (so that we can stop at ceiling directories).
Implemented find_unique_short_oid for pack backend, based on git sha1 lookup method;
finding an object given its full oid is just a particular case of searching
the unique object matching an oid prefix (short oid).
Added git_odb_read_unique_short_oid, which iterates over all the backends to
find and read the unique object matching the given oid prefix.
Added a git_object_lookup_short_oid method to find the unique object in
the repository matching a given oid prefix : it generalizes git_object_lookup
which now does nothing but calls git_object_lookup_short_oid.
A TREE extension with an entry count of -1 means that it was
invalidated and we should ignore it. Do so instead of returning an
error.
This fixes issue #202

There are two reasons why read_tree_internal might return a NULL
tree. The first one is a corrupt index, but the second one is an
invalidated TREE extension. Up to now, its only way to communicate
with its caller was through the return value being NULL or not.
Allow read_tree_internal to report its exit status independently from
the tree pointer.

Before this commit, malformed tag and signature were considered as
valid by the parser. See the test t3800-mktag.sh of git to see example
of malformed tag and signature.
If parse_section_header{,_ext} return an error, current_section
doesn't get allocated. Set it to NULL after freeing so we don't try to
free it again.

Simplify cfg_readline and at the same time fix it so that it does
really ignore empty lines.

On error, it would free the configuration object even though it didn't
own that memory, which would cause a double-free.

Make sure the user immediately sees the feedback, '.' or 'F', for a
test. If it's only in the buffer, it may gets "lost" in case of error.
