Extended lfsr_ftree_t to include the opened-mdir

Browse Source

Now that bshrubs are limited to files, we might as well lean into it.

Instead of relying on extra traversals through our attr-list, we now
rely on bsprouts/bshrubs always existing in the opened mdir list. This
is a much more robust way to deduplicate bsprout/bshrub compaction
operations. The previous implementation already had a bug since
bsprout/bshrub calculation was forgotten from lfsr_mdir_estimate_.

This is a direct tradeoff of code and RAM. Though note the previous
impl was incomplete and would likely need a bit more code:

            code          stack
  before:  33184           2944
  after:   32980 (-0.6%)   3000 (+1.9%)
