Hi,

this round there are a lot of cleanups and moved code so the diffstat
looks huge, otherwise there are some nice performance improvements and
an update to raid56 reliability. Please pull, thanks.

---

User visible features:

- raid56 reliability vs performance trade off
  - fix destructive RMW for raid5 data (raid6 still needs work) - do full RMW
    cycle for writes and verify all checksums before overwrite, this should
    prevent rewriting potentially corrupted data without notice
  - stripes are cached in memory which should reduce the performance impact but
    still can hurt some workloads
  - checksums are verified after repair again
  - this is the last option without introducing additional features (write
    intent bitmap, journal, another tree), the RMW cycle was supposed to be
    avoided by the original implementation exactly for performance reasons but
    that caused all the reliability problems

- discard=async by default for devices that support it

- implement emergency flush reserve to avoid almost all unnecessary transaction
  aborts due to ENOSPC in cases where there are too many delayed refs or
  delayed allocation

- skip block group synchronization if there's no change in used bytes, can
  reduce transaction commit count for some workloads

Performance improvements:

- fiemap and lseek
  - overall speedup due to skipping unnecessary or duplicate searches (-40% run time)
  - cache some data structures and sharedness of extents (-30% run time)

- send
  - faster backref resolution when finding clones
  - cached leaf to root mapping for faster backref walking
  - improved clone/sharing detection
  - overall run time improvements (-70%)

Core:

- module initialization converted to a table of function pointers run in a
  sequence

- preparation for fscrypt, extend passing file names across calls, dir item can
  store encryption status

- raid56 updates
  - more accurate error tracking of sectors within stripe
  - simplify recovery path and remove dedicated endio worker kthread
  - simplify scrub call paths
  - refactoring to support the full RMW write

- tree block parentness checks consolidated and done at metadata read time

- improved error handling

- cleanups
  - move a lot of code for better synchronization between kernel and user space
    sources, split big files
  - enum cleanups
  - GFP flag cleanups
  - header file cleanups, prototypes, dependencies
  - redundant parameter cleanups
  - inline extent handling simplifications
  - inode parameter conversion
  - data structure cleanups, reductions, renames, merges
