where sector size (disk block size) is required, instead of
DEV_BSIZE constant which means device I/O block size.
"Looks reasonable" from dholland@, and fixes tools installboot(8)
on Cygwin where DEV_BSIZE != 512 as mentioned in PR toolchain/42555.
_NETBSD_SOURCE as this makes cross building from older/newer versions of
NetBSD harder, not easier (and also makes the resulting tools 'different')
Wrap all required code with the inclusion of nbtool_config.h, attempt to
only use POSIX code in all places (or when reasonable test w. configure and
provide definitions: ala u_int, etc).

- unify sparc_bbinfo (1064 bytes, with 256 block entries)
and sun68k_bbinfo (296 byte, with 64 block entries)
into shared_bbinfo (512 bytes, with 118 block entries),
which will be also shared by future bbinfo-using platforms
(including macppc)
- add datestamp to *_BBINFO_MAGIC strings, to prevent installboot vs
bootxx version skew.
- add macppc support
*/bootxx.c:
- migrate to new shared_bbinfo structure
installboot:
- add macppc support (still needs applepartmap support and testing)
- improve and add some more warnings & errors to installboot
- implement shared_bbinfo_clearboot() and shared_bbinfo_setboot(), which
perform the majority of the work for bbinfo-using back-ends
(rather than replicating that across multiple back-ends).
and use instead of replicating the effort in various locations
- if filesystem is not a regular file, use sync(2) instead of fsync(2)
after the bootstrap has been written
- add `-B s2bno', to provide the starting block for the secondary bootstrap.
intended for use on platforms where the blocks of the stage2 bootstrap
are hardcoded into the stage1 bootstrap (currently: sparc, sun2)
- don't support `-b s1bno' for sparc or sun2, since the primary is always
at a fixed location on the disk.
- if `filesystem' is a regular file, use fsync(2) instead of sync(2)
code changes:
- add hardcode_stage2(), which uses -B s2bno and the size of the
provided secondary bootstrap (as an actual file, not as part of the
`filesystem' argument) to provide a sequential list of blocks from s2bno,
each block being the appropriate file system size (from
params->fstype->blocksize)
- add blocksize and needswap run-time parameters to ib_fs
- in *_match(), set params->fstype->blocksize to the underlying block size
(8KB for raw), and params->fstype->needswap as appropriate
- rename IB_STARTBLOCK to IB_STAGE1START, and add IB_STAGE2START
- use hardcode_stage2() to implement raw_findstage2() and IB_STAGE2BLOCK
support for ffs_findstage2()
- improve some comments, add some prototypes, ...
fstype checking, and back-end "ffs" support.
- Consistently use at least uint32_t for blocknumbers (vs. int / long / ...)
- Consistently use uintXX_t instead of u_intXX_t.
- Move various duplicated prototypes into "installboot.h"
