svn commit: trunk/busybox: include libbb

[landley at busybox.net]

Author: landley
Date: 2006-05-19 13:36:49 -0700 (Fri, 19 May 2006)
New Revision: 15142

Log:
A pending item in my tree I might as well check in: I plan to migrate calloc()
and bb_calloc() calls to bb_xzalloc() which allocates prezeroed memory but
only takes one argument (the size).
