This mod adds a number of optimizations to increase the
performance of xfsdump and xfsrestore, especially on filesystems
with millions of inodes. Many small changes were made to
minimize the number of system calls required per inode.
Significant changes to xfsdump:
- Cache the gen number of each inode during the initial inode
  scan so that a bulkstat single does not need to be done for
  each inode when dumping directories.
- No longer retrieve the DMF attribute when estimating the dump
  size of a file. Use information from the bulkstat instead.
- Retrieve DMF attribute by handle instead of doing
  open/attr_getf/close.
- In determining where to split multi-stream dumps, take into
  consideration the number of files and not just the file size.
  This allows filesystems with large amounts of inodes but
  relatively little data (DMF filesystem) to be split correctly.
Significant changes to xfsrestore:
- Buffer writes to the namreg file to eliminate 2 very small
  write system calls per directory entry.
- Buffer writes to dirattr file to eliminate a small write system
  call per directory.
- Speedup the check to see if a particular window of the tree
  file is mapped. This allows xfsrestore to use more, smaller
  windows which is beneficial if we can't fit them all in memory
  and have to start unmapping them. This also makes the -w
  option obsolete so that option now has no effect.
- Change the hash function to give a better distribution among
  the hash buckets.
- Do not make an unnecessary unlink call if the file being
  restored does not already exist.

Fix includes to not be relative to paths provided by -I directives, for
the xfsprogs and xfsdump builds.  At this stage still provide these gcc
options in the build but later that can be removed too now that headers
are clean.

- get rid of w_lasttouched field and the setting of it
  as it is never used and it calls time()
  many times over [ optimisations ]
- add t_winmmaps and win_getnum_mmaps()
  to see how many mmap calls for tree windows
  are made - so can check on performance
- add win_locks_on() and win_locks_off() functions
- add more diagnostics
- in win_map(), test mmap64() success instead of asserting it
