find: use NOFORK/NOEXEC; small -exec buglet also eliminated
vfork_daemon_rexec: honor PREFER_APPLETS
echo: small size improvements
find -exec echo {} \; with PREFER_APPLETS=y runs 4 times faster
and now this fact is recorded in applets.h, not ash.c.
Several fixes to "--help + STANDALONE_SHELL" scenarios.

runs more than twice as fast with STANDALONE_SHELL versus without.
It's a GPL-ed 'clone' of Dan Bernstein's tcpserver.

teach scripts/individual new tricks. And while I'm at it, teach
scripts/individual other new tricks. Now builds 198 applets, some of which
I should teach it to hardlink together because they're really the same app...
the following of which (from cat.c) belongs in svn history instead of the
source code:
/* Mar 16, 2003 Manuel Novoa III (mjn3@codepoet.org)
*
* This is a new implementation of 'cat' which aims to be SUSv3 compliant.
*
* Changes from the previous implementation include:
* 1) Multiple '-' args are accepted as required by SUSv3. The previous
* implementation would close stdin and segfault on a subsequent '-'.
* 2) The '-u' options is required by SUSv3. Note that the specified
* behavior for '-u' is done by default, so all we need do is accept
* the option.

the side of the tree doesn't _COUNT_, and I will not ship it.
Udhcp was deleted shortly after I posted my philosophy for what should and
shouldn't go into busybox:
http://www.busybox.net/lists/busybox/2006-March/019484.html
I complained about the change t the time. I've complained repeatedly since.
But nobody felt like fixing it. External dependencies are something to be
minimized. I don't care about the ability for packages to build outside
busybox: something is either part of busybox, or it isn't. If I convert any
part of the external udhcp repository to use libbb, I've broken the external
package. Any random cleanups that touch that directory suddenly have to worry
about external dependencies that are NOT OUR PROBLEM. Therefore, that
directory is not and cannot be part of busybox. Wishful thinking isn't going
to change that. I will not ship something I can't maintain.
I'll try to get a new dhcp client and server in before the ship window closes,
but I have a half-dozen other projects pending. I'm sorry this happened, but
I'm not the one who removed it, and I'm not the one who ignored the project
maintainer's repeated complaints about the situation for the next month and a
half.
