refs: add GIT_TRACE_REFS debugging mechanism
When set in the environment, GIT_TRACE_REFS makes git print operations and
results as they flow through the ref storage backend. This helps debug
discrepancies between different ref backends.
Example:
$ GIT_TRACE_REFS="1" ./git branch
15:42:09.769631 refs/debug.c:26 ref_store for .git
15:42:09.769681 refs/debug.c:249 read_raw_ref: HEAD: 0000000000000000000000000000000000000000 (=> refs/heads/ref-debug) type 1: 0
15:42:09.769695 refs/debug.c:249 read_raw_ref: refs/heads/ref-debug: 3a238e539bcdfe3f9eb5010fd218640c1b499f7a (=> refs/heads/ref-debug) type 0: 0
15:42:09.770282 refs/debug.c:233 ref_iterator_begin: refs/heads/ (0x1)
15:42:09.770290 refs/debug.c:189 iterator_advance: refs/heads/b4 (0)
15:42:09.770295 refs/debug.c:189 iterator_advance: refs/heads/branch3 (0)
