IABSD: new features for msdos (FAT) filesystems

New features for msdos (FAT16/FAT32) filesystems are coming in for the upcoming first release of IABSD-0.1 :

• Reduced time for newfs_msdos by 3600 times by batching writes and using recommended default values for block size and cluster sizes. What took 5 hours now takes 5 seconds, like formatting a 512GB USB-3 memory stick.
• Added regression tests for bad bugs in msdosfs fhtovp if you use it over NFS (maybe no-one is affected by this but never mind I'll fix it). Crafted file handles can overwrite kernel memory. Be advised !
• Will fix bugs and report in this file :
  • sys/msdosfs/README.md on git.kmx.io
  • sys/msdosfs/README.md on Github
  • sys/msdosfs/README.md on Codeberg
