Major rework of the directory structure and the entire build system. -Erik

/* vi: set sw=4 ts=4: */
/*
A couple things that got tangled up in my tree, easier to check in both than untangle them: Rewrite u_signal_names() into get_signum() and get_signame(), plus trim the signal list to that required by posix (they can specify the numbers for the rest if they really need them). (This is preparatory cleanup for adding a timeout applet like Roberto Foglietta wants.) Export the itoa (added due to Denis Vlasenko, although it's not quite his preferred implementation) from xfuncs.c so it's actually used, and remove several other redundant implementations of itoa and utoa() in the tree.
