Make sure daddr_t is a 64 bit type when building tools.

Rename min/max -> uimin/uimax for better honesty.

These functions are defined on unsigned int. The generic name
min/max should not silently truncate to 32 bits on 64-bit systems.
This is purely a name change -- no functional change intended.

HOWEVER! Some subsystems have

#define min(a, b) ((a) < (b) ? (a) : (b))
#define max(a, b) ((a) > (b) ? (a) : (b))

even though our standard name for that is MIN/MAX. Although these
may invite multiple evaluation bugs, these do _not_ cause integer
truncation.

To avoid `fixing' these cases, I first changed the name in libkern,
and then compile-tested every file where min/max occurred in order to
confirm that it failed -- and thus confirm that nothing shadowed
min/max -- before changing it.

I have left a handful of bootloaders that are too annoying to
compile-test, and some dead code:

cobalt ews4800mips hp300 hppa ia64 luna68k vax
acorn32/if_ie.c (not included in any kernels)
macppc/if_gm.c (superseded by gem(4))

It should be easy to fix the fallout once identified -- this way of
doing things fails safe, and the goal here, after all, is to _avoid_
silent integer truncations, not introduce them.

Maybe one day we can reintroduce min/max as type-generic things that
never silently truncate. But we should avoid doing that for a while,
so that existing code has a chance to be detected by the compiler for
conversion to uimin/uimax without changing the semantics until we can
properly audit it all. (Who knows, maybe in some cases integer
truncation is actually intended!)

Make the userland signature and uses of bread() match the kernel ones,
after the removal of the cred argument.

- don't abuse vp->fs to mean struct fs for ffs and struct msdos_opts;
make it always fsinfo_t and change void * to that.
- kill unused structure members.

buf is generic; it has nothing to do with ffs and will eventually be moved.
gc sectorize.

makefs - create a file system image from a directory tree.
It doesn't need any special privileges or kernel devices.

Only ffs image creation is supported at this time, although makefs has been
designed to allow the addition of other file system formats by writing new
back-ends.

This program was designed & implemented by Luke Mewburn of Wasabi Systems.
