67b23e6043 getopt_ulflags -> getopt32. 
It is impossible to formulate sane ABI based on
size of ulong because it can be 32-bit or 64-bit.
Basically it means that you cannot portably use
more that 32 option chars in one call anyway...
Make it explicit.

d921b2ecc0 Remove bb_ prefixes from xfuncs.c (and a few other places), consolidate 
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.)

db1ab1aeb3 Top was catching sigterm (and fumbling sigint) so it could reset the terminal 
type on the way out, but the signal handler didn't exit.  Plus it did
unnecessary things with sigaction.  This code is overgrown and needs a serious
weed-whacking...

e2922e42a0 - make it C89 compatible; Declarations in the middle of a function is of course 
fine in C99, but it really serves no purpose other than breaking compilation

This is a bulk spelling fix patch against busybox-1.00-pre10.
If anyone gets a corrupted copy (and cares), let me know and
I will make alternate arrangements.

Erik - please apply.

Authors - please check that I didn't corrupt any meaning.

Package importers - see if any of these changes should be
passed to the upstream authors.

I glossed over lots of sloppy capitalizations, missing apostrophes,
mixed American/British spellings, and German-style compound words.

What is "pretect redefined for test" in cmdedit.c?

Good luck on the 1.00 release!

Erik,

The format for /proc/meminfo has changed between 2.4 and 2.6, quite considerably.
In addition to the removal of the two-line summary that was present in 2.4,
MemShared was also removed. Presently (at least in busybox CVS HEAD), top fails
to parse this correctly and spews forth a:

top: failed to read 'meminfo'

message. This patch switches around some of the semantics a little to do sane
parsing for both 2.4 and 2.6. Also, in the event that the summary gets yanked
from 2.4, this patch will deal with that as well. With this patch, I'm able
to run top correctly on 2.6.0-test7 (tested on sh).

Please apply.
