(we were not respecting order of actions!).
Add -o and -a handling.

(was doing zillions of 1-byte write syscalls)

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.)

Hi.
Last changes (rev 1.12) to recursive_actions() by Christian Grigis
have problem.
Test for demonstrate:
$ mkdir aaa bbb ccc
$ su
# chown root bbb
# chmod 700 bbb
# exit
$ busybox chmod 777 -R .
./bbb: Permision denied
But "./ccc" mode not changed. Previous variant works fine,
errors skiped and continued recursion.

Hello everyone,
Busybox's insmod fails to locate a module when that module is the only one
existing in the /lib/modules directory (with a unique name).
Example:
# find /lib/modules/ -type f
/lib/modules/kernel/drivers/char/bios.o
# insmod bios
insmod: bios.o: no module by that name found
# touch /lib/modules/dummy
# find /lib/modules/ -type f
/lib/modules/kernel/drivers/char/bios.o
/lib/modules/dummy
# insmod bios
Using /lib/modules/kernel/drivers/char/bios.o
As long as there is another file in the /lib/modules directory, insmod
finds it OK.
I tracked the problem down to 'check_module_name_match()' in insmod.c:
It returns TRUE when a match is found, and FALSE otherwise. In the case
where there is only one module in the /lib/modules directory (or more that
one module, but all with the same name), 'recursive_action()' will return
TRUE and we end up on line 4196 in 'insmod.c' which returns an error.
[The reason it works with more than one module with different
names is that in this case there will always be one not matching,
'recursive_action()' will return FALSE and we end up in line 4189.]
Now, from the implementation of 'recursive_action()' and from other
usages of it (tar.c, etc.), it seems to me that FALSE should be returned
to indicate that we want to stop the recursion, so TRUE and FALSE should
be inverted in 'check_module_name_match()'.
At the same time, 'recursive_action()' continues to recurse even after
the recursive call has returned FALSE; again in my understanding and
other usages of it, we can safely stop recursing at this point.
Here is my patch against 1.00-pre8:

This way, we can new get rid of all that tedious #define rubbish we used to
need to enable specific messages. This way is enormously simpler, and as a
bonus also ends up saving us 96 bytes.
