Extended test_files to test file btrees (up to 4*BLOCK_SIZE)

Browse Source 
Unfortunately, the tests are starting to take a painfully long time to
run. Some of this is because, in order to get interesting file
topologies, we need to move a ton of data around, but some of this is
also because our current write implementation has some problematically
expensive corner cases.

I have quite a few ideas on how to improve this, but in the meantime the
tests needed to be aggressively trimmed in order to keep development
tolerable (A happy developer is a productive developer).

This mainly meant:

- Disabled powerloss testing on file tests for now.

  The reality is that naivly powerloss testing the file tests, i.e.
  just truncating the file after each restart, provides very little
  value and adds an extreme amount of runtime.

  Removed for now. Most of the powerloss file creation concerns are
  covered in the dtree tests, and we should eventually add powerloss
  tests tailored to recovering files after powerloss instead of just
  truncating.

- Avoided tiny fragment sizes with large file sizes.

  Tiny fragments are a degenerate case and end up with excessive
  overhead (1 byte fragment => 41x overhead!). But they are useful for
  revealing subtle bugs. Still, it just doesn't make sense time-wise to
  test with tiny fragments once the file size exceeds ~1 block.

- Limited fuzz tests to cover fewer random seeds.

  We can increase these if performance improves, but even if not, we can
  run these individually with a high number of seeds in CI.

Also fixed a number of bugs found by the extended testing, which is
always a good sign:

- Yet another `lfsr_data_size(&data)` vs `data.u.disk.size` typo.

  This is the first time I've seen a real world argument for private
  struct/class fields, but I am still against the concept.

- Fixed delta/weight miscalculation when tree-carving a left sibling.

- Fixed missing offset in hole writing during block writes.

- Worked around lfsr_file_readnext's reliance on file->size when we are
  using it to write to a block. This may be more a hack than a good
  long term solution though.

- Checkpointed the allocator in both lfsr_file_write and lfsr_file_sync.

  Otherwise calling lfsr_file_write repeatedly can easily trigger an
  incorrect ENOSPC.

- Correctly reverted both shrubs and btrees in truncate/fruncate

  This gets a bit more complicated in fruncate, since either one of the
  two, or both, can revert.

  truncate/fruncate probably deserve a bit more work around reversions
  to simpler data structures, as is.

- Added handling of shrub overflows during fruncate.

  Notably not possible with truncate, shrub overflows require that we
  1. flush the shrub, 2. fruncate the tree, 3. and make sure any side
  effects to the buffer are handled correctly.
