Apply the following patch submitted by Evgeniy Ivanov:
http://mail-index.NetBSD.org/tech-kern/2011/12/15/msg012226.html

 - add 'ls' op to struct fs_ops to support ls command on each fs,
   enabled by -DLIBSA_ENABLE_LS_OP and SAMISCMAKEFLAGS+="SA_ENABLE_LS_OP=yes"
   in libsa
 - split sys/lib/libsa/ufs_ls.c into UFS specific part and MI part (ls.c)
   that opens the target fs and calls fs-depedent XXX_ls() functions
 - add a ls op for ext2fs
   (all other fs than ufs and ext2fs don't have actual ls ops yet)
 - replace existing MD ufs_ls() calls with this new MI ls()

The original patch was written for i386 and ext2fs.
zaurus zboot has been tested by nonaka@.
ews4800mips and x68k loaders have been tested by me (with several fixes).
landisk might be okay since it was almost copied from i386.

XXX1: "ls" op in fs_ops looks a bit inconsistent, but we will be able to
      replace it with real fs ops like readdir if it's really worth
XXX2: someone might have to check sys/arch/ia64/stand/efi/libefi/efifs_ls.c

Fix printf formating in ifdef DEBUG sections.

Catchup with rmind-uvmplock merge.

Add an optional MD calling convention flag for use in libsa when space
optimisation is critical. Use this on i386 to switch to register passing
calling convention for the file system entry points and most assembler
call backs that have to preserve at least 3 registers.

Replace time_t values in libsa sources with the following two types
to avoid unnecessary 64 bit ops which would make binaries larger:

satime_t (currently unsigned int):
 numbers in seconds returned by the machine dependent getsecs() function
 which are used to measure relative time

saseconds_t (currently int):
 numbers in seconds used to specify timeout to network drivers

Extend tftp_stat to return the size of the file, rather than -1.

It's not very efficient, as it has to read the whole file, and count the
block sizes.  However, this is the only way to work out the size using the
tftp protocol.

This is needed to support loading modules from a tftp server with pxeboot.

fix damage in error handling crept in in 1.4

Make a bunch of backward-compatible changes to the boot blocks which allow
size to be reduced substantially.  (backward compatibility verified
by compiling one of the alpha boot blocks which uses all of the code
before and after, diffing the object files, and manually verifying that
the differences were 'correct'.  some differences were "unavoidable,"
it wanting to avoid a double-commit, because e.g. local variables which
were previously used were no longer used.)  a README which describes
supported options (or at least the ones mentioned below) is forthcoming.

add support for the preprocessor macro LIBSA_NO_TWIDDLE, which
  causes calls to twiddle() to be omitted if it's defined.
add support for the preprocessor macros:
	LIBSA_NO_FS_CLOSE
	LIBSA_NO_FS_WRITE
	LIBSA_NO_FS_SEEK
  which, if defined, cause the corresponding file system operations
  in the individual file system implementations to be omitted.  (note
  that all of those macros are not supported by all file systems at
  this point.  comments were added to individual file system files
  to indicate lack of support, and should be cleaned up later.  Backward
  compatibility options e.g. UFS_NOCLOSE, etc., are supported.)
add support for the preprocessor macro LIBSA_NO_FS_SYMLINK, which
  removes support for symbolic links from the file system support
  functions.  (same notes as for the macros above apply.)
add support for the preprocessor macro LIBSA_FS_SINGLECOMPONENT which
  removes all subdirectory and symlink support from the file system
  support functions.  (same notes as for the macros above apply.)
add support for the preprocessor macro LIBSA_NO_FD_CHECKING, which
  causes code relating to libsa file descriptor checks (e.g. range
  checking and checking that a file descriptor is valid) to be
  omitted if it's defined.
add support for the preprocessor macro LIBSA_NO_RAW_ACCESS, which
  causes code relating to raw device access to be omitted if it's
  defined.
change some structure copies to use bcopy() instead.  that way
  use of bcopy vs. memcpy() can easily be selected by
  LIBSA_USE_MEMCPY.  (without changes like these, you could end up
  having both bcopy() and memcpy() included.  eventually, all
  calls to bcopy should be changed to calls to memcpy() or memmove()
  as appropriate -- hopefully never the latter -- with an option to
  use bcopy instead.)
add support for the preprocessor macro LIBSA_NO_DISKLABEL_MSGS, which
  causes disklabel() to return '1' as msg rather than a string.  Can
  be used if the boot blocks don't care about the string, and need to
  save the space.
add support for the preprocessor macro LIBSA_SINGLE_FILESYSTEM, which
  if defined causes all of the file system switch code to be removed.
  Its value should be the name of the file system supported by the
  boot block, e.g. "ufs" for the FFS file system.  calls to the
  file system functions open, close, etc., which were previously
  done through a function switch are then done via direct invocation
  of <fs>_open, <fs>_close, etc. (e.g. ufs_open, ...).
add support for the preprocessor macro LIBSA_SINGLE_DEVICE, which
  does the equivalent of LIBSA_SINGLE_FILESYSTEM but for the device
  switch table.  Device entry pointes are expected to be named
  <dev>foo, e.g. the 'strategy' routine used when LIBSA_SINGLE_DEVICE
  is set to 'disk' is diskstrategy.
make ufs.c f_nindir array be unsigned ints.  the fact that it was signed
  caused ufs.c to require signed division routines (which were otherwise
  unnecessary for a small boot block).

Changes to compile the next68k bootblocks with
egcs -Wpointer-arith -Wstrict-prototypes

Made this compile:
- fifth arg to recvtftp should be size_t (not ssize_t)
- the path is passed tftp_makereq as a part of the handle structure

Add missing prototypes for static functions.
