	depmod
	busybox lacks a way to update module deps when running from firmware without the
	use of the depmod.pl (perl is to bloated for most embedded setups) and or orig
	modutils. The orig depmod is rather pointless to have to add to a firmware image
	in when we already have a insmod/rmmod and friends.
	Unify base64 handling.
	There's base64 encoding and decoding going on in:
	networking/wget.c:base64enc()
	coreutils/uudecode.c:read_base64()
	coreutils/uuencode.c:tbl_base64[]
	networking/httpd.c:decodeBase64()
	And probably elsewhere.  That needs to be unified into libbb functions.
