61c92110e6 Change documentation inaccuracy on chunk size. 
We know use only "target chunk size" when speaking of the chunk size
that is expected to happen most of the time. This removes statistical
and mathematical inacurracies that could be troublesome for mathematical
people.

Fixes #5336

Fixed locking, issue #4923 (#4928) 
locking: fix ExclusiveLock race condition bug, fixes #4923

- ExclusiveLock is now based on os.rename instead of os.mkdir.
- catch FileNotFoundError observed under race condition in ExclusiveLock.release()
  and .kill_stale_lock()
- added TestExclusiveLock.test_race_condition() which reveals issue #4923
- updated docs
- locking: use "raise LockTimeout from None" for prettier traceback

5e2de8ba67 implement files cache mode control, fixes #911 
You can now control the files cache mode using this option:

--files-cache={ctime,mtime,size,inode,rechunk,disabled}*

(only some combinations are supported)

Previously, only these modes were supported:
- mtime,size,inode (default of borg < 1.1.0rc4)
- mtime,size (by using --ignore-inode)
- disabled (by using --no-files-cache)

Now, you additionally get:
- ctime alternatively to mtime (more safe), e.g.:
  ctime,size,inode (this is the new default of borg >= 1.1.0rc4)
- rechunk (consider all files as changed, rechunk them)

Deprecated:
- --ignore-inodes (use modes without "inode")
- --no-files-cache (use "disabled" mode)

The tests needed some changes:
- previously, we use os.utime() to set a files mtime (atime) to specific
  values, but that does not work for ctime.
- now use time.sleep() to create the "latest file" that usually does
  not end up in the files cache (see FAQ)

bf69b049e9 be clear about what buzhash is used for, fixes #2390 
and want it is not used for (deduplication).

also say already in the readme that we use a cryptohash
for dedupe, so people don't worry.
