38f6319421 cmdedit is not a 'command' editing anymore, it's just editing (generic), 
so rename stuff accordingly.

Denis Vlasenko
8e1c71529c Convert cmdedit into more generic line input facility 
(make history and completion optional at runtime).
Use it for fdisk, as an example.
Some unrelated fixes in fdisk are also here.

Yet another attempt on saner function names:

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).

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.)
