3476ad651d Second drop. More infrastructure in place, especially for parsing pipelines. 
The minimal version got a couple hundred bytes bigger, partly because it's
broken into more functions but mostly because it now dynamically reallocates
and frees everything with no hard-coded limits.  (I thought about making
that optional, but there's a limit to what I can debug and maintain.  It
should still be reasonably NOMMU friendly, the allocations are small and
short lived, and shouldn't contribute noticeably to long-term memory
fragmentation.)

02add9e53a Might as well commit this to have the history. It's not linked in to the 
applet list yet (and won't be until it can replace lash, I'm not having five
shells in menuconfig at once), but you can build it with scripts/individual
and mostly this is checked in so I can bloatcheck future versions against it
easily....

This is about as small as a shell can get and still be a shell.

88621d7398 Svn 16007 broke the build under gcc 4.0.3. This fixes up some of the damage 
(the e2fsprogs directory is too twisty and evil to easily fix, but I plan
to rewrite it anyway so I'll just bump that up in priority a bit).

things like xasprintf() into xfuncs.c, remove xprint_file_by_name() (it only
had one user), clean up lots of #includes...  General cleanup pass.  What I've
been doing for the last couple days.

And it conflicts!  I've removed httpd.c from this checkin due to somebody else
touching that file.  It builds for me.  I have to catch a bus.  (Now you know
why I'm looking forward to Mercurial.)

c9c1a41c58 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.

6ab037872f made "test" an ash built-in. 
moved the contents of libbb/bb_echo.c back into coreutils/echo.c,
which is a more reasonable place for them than libbb.  this
forces anyone who wants echo and test to be builtin to ash to
also have them available as applets.  their cost is very small,
and the number of people who wouldn't want them as applets is
also very small.

added warning about shell builtins vs. CONFIG_FEATURE_SH_STANDALONE_SHELL,
which conflicts with their use.

thanks to nathanael copa for debugging help.

some string size optimization in test.c may have been lost with
this commit, but this is a good new baseline.

0fcd9430ce This one's from me. Fix ash "standalone shell". 
If we exec /proc/self/exe and only fall back to /bin/busybox if /proc isn't
there, then we have a reasonable chance of having the standalone shell work
even if busybox isn't installed in /bin on the system in question.

Still won't work in a chroot environment, but it's an improvement.
