Use designated initializers for struct ib_mach.

fix various gcc-4.5 warnings

A checksum value in alpha boot block is stored in little endian,
so use le64toh() to print it on the host tool.
While here, use consistent (unsignd long long) casts on printing it.

Coverty 7449: Change 'return (0)' to 'goto done' so we free(bootstrapbuf)
before exiting with error.

Move the MD definitions into the MD files, leaving machines.c with just
a list of the supported machines.

Overhaul how `build.sh tools' are used:

* Rename "config.h" to "nbtool_config.h" and
HAVE_CONFIG_H to HAVE_NBTOOL_CONFIG_H.
This makes in more obvious in the source when we're using
tools/com

Overhaul how `build.sh tools' are used:

* Rename "config.h" to "nbtool_config.h" and
HAVE_CONFIG_H to HAVE_NBTOOL_CONFIG_H.
This makes in more obvious in the source when we're using
tools/compat/config.h versus "standard autoconf" config.h

* Consistently move the inclusion of nbtool_config.h to before
<sys/cdefs.h> so that the former can provide __RCSID() (et al),
and there's no need to protect those macros any more.

These changes should make it easier to "tool-ify" a program by adding:
#if HAVE_NBTOOL_CONFIG_H
#include "nbtool_config.h"
#endif
to the top of the source files (for the general case).

user visible stuff:

user visible stuff:
- 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, ...
