netif_open: Fail with ENXIO instead of panic if no netif available

Avoid undesirable freeze for efiboot/x86 when interfaces are really
unavailable, or fail to be configured by buggy UEFI firmware.

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

Per discussion on current-users.

- use mem* instead of b* routines, and kill the b* routines.
- use the mem* routines from libc.
XXX: There will be some lossage, but I am fixing it.

Hi Perry!

nuke trailing whitespace

separate the netif interface from the rest of the networking code,
so that it can be replaced easily in md code

Catch up to -current.

sync kqueue with -current; this includes merge of gehenna-devsw branch,
merge of i386 MP branch, and part of autoconf rototil work

remove trailing \n in panic().  approved perry.

Backout my libsa changes.

Update for the improvements to libsa, and don't reference libkern.h.

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).

Add missing prototypes.

Update marc-pcmcia branch from trunk.

-Wall fixes

Avoid user space headers for standalone programs.
Don't use sys/lib/libkern or sys/lib/libz if not standalone
 (ie, user space test programs).

-Wall fixes

backout previous kprintf changes

printf -> kprintf, sprintf -> ksprintf

Another round of clean up, including fixes presented by Matthias Drochner
(PR#1404). Things to be noted:
	- all IP addresses are now `struct in_addr's.
	- the function rarp_getipaddress() no longer return `myip'; in stead
	  it returns -1 on failure (errno set), 0 on success. `myip' is set
	  as a size-effect.

Clear up some size_t/ssize_t confusion.

Define netif_debug in here.

new RCS ID format.
