odb_pack: try lookup before refreshing packs This reduces the rate of syscalls for the common case of sequences of object reads from the same pack. Best of 5 timings for libgit2_clar before this patch: real 0m5.375s user 0m0.392s sys 0m3.564s After applying this patch: real 0m5.285s user 0m0.356s sys 0m3.544s 0.6% improvement in system time. 9.2% improvement in user time. 1.7% improvement in elapsed time. Confirmed a 0.6% reduction in number of system calls with strace. Expect greater improvement for graph-traversal with large packs.
