It turns out that parse_object() is loading and decompressing given
object to free it just before calling the specific object parsing
function which does mmap and decompress the same object again. This
patch introduces the ability to parse specific objects directly from a
memory buffer.
Without this patch, running git-fsck-cache on the kernel repositorytake:
real 0m13.006s
user 0m11.421s
sys 0m1.218s
With this patch applied:
real 0m8.060s
user 0m7.071s
sys 0m0.710s
The performance increase is significant, and this is kind of a
prerequisite for sane delta object support with fsck.

The tree object parsing used to get the executable bit wrong,
and didn't know about symlinks. Also, fsck really wants the
full mode value so that it can verify the other bits for sanity,
so save it all in struct tree_entry.

We check the ordering of the entries, and we verify that none
of the entries has a slash in it (this allows us to remove the
hacky "has_full_path" member from the tree structure, since we
now just test it by walking the tree entries instead).

This adds the contents of trees to struct tree.

This adds the structs and function declarations for parsing git objects.
