list-objects-filter: teach tree:# how to handle >0
Implement positive values for <depth> in the tree:<depth> filter. The
exact semantics are described in Documentation/rev-list-options.txt.
The long-term goal at the end of this is to allow a partial clone to
eagerly fetch an entire directory of files by fetching a tree and
specifying <depth>=1. This, for instance, would make a build operation
fast and convenient. It is fast because the partial clone does not need
to fetch each file individually, and convenient because the user does
not need to supply a sparse-checkout specification.
Another way of considering this feature is as a way to reduce
round-trips, since the client can get any number of levels of
directories in a single request, rather than wait for each level of tree
objects to come back, whose entries are used to construct a new request.

cache: make oidcpy always copy GIT_MAX_RAWSZ bytes
There are some situations in which we want to store an object ID into
struct object_id without the_hash_algo necessarily being set correctly.
One such case is when cloning a repository, where we must read refs from
the remote side without having a repository from which to read the
preferred algorithm.
In this cases, we may have the_hash_algo set to SHA-1, which is the
default, but read refs into struct object_id that are SHA-256. When
copying these values, we will want to copy them completely, not just the
first 20 bytes. Consequently, make sure that oidcpy copies the maximum
number of bytes at all times, regardless of the setting of
the_hash_algo.
Since oidcpy and hashcpy are no longer functionally identical, remove
the Cocinelle object_id transformations that convert from one into the
other.

tree-walk: store object_id in a separate member
When parsing a tree, we read the object ID directly out of the tree

oidcpy, which copies GIT_MAX_RAWSZ bytes, because if we are using SHA-1,
there may not be that many bytes to copy.
Instead, store the object ID in a separate struct member. Since we can
no longer efficiently compute the path length, store that information as
well in struct name_entry. Ensure we only copy the object ID into the
new buffer if the path length is nonzero, as some callers will pass us
an empty path with no object ID following it, and we will not want to
