Merge branch 'ps/object-wo-the-repository'

The object layer has been updated to take an explicit repository
instance as a parameter in more code paths.

* ps/object-wo-the-repository:
  hash: stop depending on `the_repository` in `null_oid()`
  hash: fix "-Wsign-compare" warnings
  object-file: split out logic regarding hash algorithms
  delta-islands: stop depending on `the_repository`
  object-file-convert: stop depending on `the_repository`
  pack-bitmap-write: stop depending on `the_repository`
  pack-revindex: stop depending on `the_repository`
  pack-check: stop depending on `the_repository`
  environment: move access to "core.bigFileThreshold" into repo settings
  pack-write: stop depending on `the_repository` and `the_hash_algo`
  object: stop depending on `the_repository`
  csum-file: stop depending on `the_repository`
