Ifconfig cleanup.
Move xgetpwuid() and xgetgrgid() into xwrap.c
Add xgetpwnam() to lib/xwrap.c.
Oops, cleaned up ifconfig uses atolx_range() instead of get_int_list(). Check that in.
Promote ifconfig from pending to other.
Cleanup help text, remove dead fields unused by linux kernel.
Fix cut.

Some commands went in before "pending", and thus need cleanup but are enabled
in defconfig. The fact cut used a function out of lib/pending.c is a hint
it might be in this category...
Minor drive-by cleanups to cpio. Whitespace, curly brackets, replace %4 with &3, turn a switch/case into if/else.
Merge branch 'master' into build
Redo od whitespace with multiple output types so the columns align.

Factor out single output type into od_out_t(), call it in a loop for each type
finding largest output (and if output consumes more than one byte of input
average rounding up), pad each output to the largest output times number of
bytes input consumed.
