2.53.3

2.53.3 contains bugfixes and improvements.

• On Linux, allow syncing the xattrs where POSIX draft ACLS are
  stored, which enables syncing the ACL info. (Note that this does
  not enable syncing ACLs with the -acl switch, and does not
  enable syncing ACLs between other systems and Linux. See the
  manual.)
• Improved ETA calculation and sync speed display in text UI.
• Fix CI Windows builds (again).
• Drop unmaintained "make install" target.
• Bugfixes, minor improvements, cleanups.
