various calcipg() fixes:
...
- fix round-off errors when determining the number of inodes per group,
which often resulted in the total number of inodes in the file system
being less than what the density asked for.
now you might get more inodes than requested for a given density,
rather than less.
- if the new inodes/group is <= 0, ensure that it's at least 1, preventing
a possible division by zero or other wacky problems
- use long long instead of quad_t

remove third argument (`int ns') from ffs_sb_swap(), and let ffs_sb_swap()
...
determine the endianness of the `struct fs *o' superblock from o->fs_magic
and set needswap as necessary, rather than trusting the caller to get
it right. invariably, almost every caller of ffs_sb_swap() was calling it
with ns set to the wrong value for ns anyway!
ansi KNF ffs_bswap.c declarations whilst here.
this fixes all sorts of problems when trying to use other-endian file systems,
notably the kernel trying to access memory *way* off, possibly corrupting or
panicing, and userland programs SEGVing and/or corrupting things (e.g,
"fsck_ffs -B" to swap a file system endianness).
whilst the previous rev of ffs_bswap.c (1.10, 2000/12/23) made this problem
worse, i suspect that the problem was always there and previous versions
just happened not to trash things at the wrong time.
FFS_EI should now be a lot more stable.

Modify newfs so that the root node (and lost+found dir, if created)
...
of the new fs has uid.gid equal to the euid.egid of the process
which made it. This change permits users who have write access to
a device (say a floppy) to create a filesystem that, when mounted,
they have write access to.
This change closes PR bin/5990 from jbernard@ox.mines.edu , and is also the
change requested in PR bin/6276 from "Charles M. Hannum" <mycroft@netbsd.org>

Bayucan, bayucan@nas.nasa.gov . Minor mods by me.
