Christian Couder dae556bdb1 environment: add global variable to disable replacement
This new "read_replace_refs" global variable is set to 1 by
default, so that replace refs are used by default. But
reachability traversal and packing commands ("cmd_fsck",
"cmd_prune", "cmd_pack_objects", "upload_pack",
"cmd_unpack_objects") set it to 0, as they must work with the
original DAG.

Christian Couder 6809557029 replace_object: add mechanism to replace objects found in "refs/replace/"
The code implementing this mechanism has been copied more-or-less
from the commit graft code.

This mechanism is used in "read_sha1_file". sha1 passed to this
function that match a ref name in "refs/replace/" are replaced by
the sha1 that has been read in the ref.

We "die" if the replacement recursion depth is too high or if we
can't read the replacement object.
