Updates ls-tree.c to use read_tree_with_tree_or_commit_sha1()
function. The command can take either tree or commit IDs with
this patch.

ls-tree unconditionally called read_sha1_file() for all paths
even when not needed, which was a mistake introduced by me.
Rectify this by first checking S_ISDIR(mode) and read the tree
contents only when it is a tree and we are recursive. There is
no need to read it in any other cases.
The patch also removes the confusing comment that led to this
incorrect implementation.
Thanks to Peter Baudis for noticing this problem.

This adds '-r' (recursive) option and '-z' (NUL terminated)
option to ls-tree. I need it so that the merge-trees (formerly
known as git-merge.perl) script does not need to create any
temporary dircache while merging. It used to use show-files on
a temporary dircache to get the list of files in the ancestor
tree, and also used the dircache to store the result of its
automerge. I probably still need it for the latter reason, but
with this patch not for the former reason anymore.
It is relative to bb95843a5a0f397270819462812735ee29796fb4

Now there is error() for "library" errors and die() for fatal "application"
errors. usage() is now used strictly only for usage errors.

ls-tree tool provides just a way to export the binary tree objects
to a usable text format. This is bound to be useful in variety
of scripts, although none of those I have currently uses it.
But e.g. the simple script I've sent to HPA for purging the object
database uses it.
