e3b65ab43d switch_root: don't bail out when console doesn't exist
Busybox is very often used in initramfs at the end of which usually
there is a switch_root to the actual rootfs. There are many cases where
the console kernel argument is either just a placeholder (for example
RaspberryPi uses serial0 and serial1) or configured as null to avoid any
console messages - usually you would see such of a setup in production
environments.

Currently busybox bails out if can't open the console argument. If this
happenes in initramfs and if the console=null for example, you get in a
blind kernel panic. Avoid this by only warning instead of dying.

67b23e6043 getopt_ulflags -> getopt32.
It is impossible to formulate sane ABI based on
size of ulong because it can be 32-bit or 64-bit.
Basically it means that you cannot portably use
more that 32 option chars in one call anyway...
Make it explicit.

22d26fc6ae Patch from Yann Morin to put BLKGETSIZE64 in platform.h had rather a lot of
fallout due to the #include <sys/mount.h>.  Removed that #include from various
applets and fixed up those that were unhappy when that #include was made
because they'd block copied stuff out of it.  (Sigh.)

0f34a821ab Add a switch_root utility (like kconfig's utils/run_init.c, although not
actuall using any of that code).  This is needed because pivot_root doesn't
work right under initramfs.  (See the menuconfig help.)
