Change libdisk and sysinstall to use d_addr_t rather than u_long for disk

addresses.  For arch's with 64-bit longs, this is a nop, but for i386 this
allows sysinstall to properly handle disks and filesystems > 1 TB.

Changes from the original patch include:
- Use d_addr_t rather than inventing a blkcnt type based on int64_t.
- Use strtoimax() rather than strtoull() to parse d_addr_t's from config
  files.
- Use intmax_t casts and %jd rather than %llu to printf d_addr_t values.

Tested on:	i386
Tested by:	kuriyama
Submitted by:	julian
MFC after:	1 month
