b9ad75fa60 copy_file: handle "cp /dev/foo file" (almost) compatibly to coreutils. 
(almost because we do not copy mode, which is probably wasn't intended).

7510384107 do not do utime() on links, it acts on link targets, and we don't want that. 
rename link_name to link_target, less confusing this way.

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.)

c983274565 The logic to make cp -d or -P treat things like regular files should only 
trigger for symlinks, not for device nodes.  This should fix "cp -a /dev ."
to work as expected (when run by root, anyway).

While I was there, cleanup headers and make an #ifdef go away...

1219879422 Dont try and preserve hard links to directories. 
The linux kernel doesnt allow hard links to directories, SUS says its
implementation specific.
cramfs gives empty directories and 0 length files the same node it
makies it difficult to distinguish from hard links.

817565a0ff For the time being, revert the changes for detecting copying 
a directory into itself.  It is harder to do this correctly
than it appears.  Not trying at all seems a better compromise
for the time being, untill we can implement this correctly.

As Manuel points out, this is a flawed fix, and doesnt fix the
following:

mkdir -p cpa cpb cpc
cp -a cpa cpa/cpb/cpc

Attached what appears to be a more sane fix.  Apply on top of previous.
Please confirm sanity.

I was adding -s/--symbolic-link support to busybox cp when I noticed a

mkdir -p test/out

busybox cp -a * out/

Will never return until we run out of open files or similar.
Coreutils cp on the other hand will error with "cannot copy a directory,
`out', into itself, `out'".  Patch attached.

cp does not truncate existing destinations.  That is, after
running

 echo foo > foo
 echo fubar > fubar
 cp foo fubar

the contents of fubar are

 foo
 r

7ffe133864 As we no longer use function pointers for read in common archiving code 
archive_xread can be replaced with bb_full_read, and archive_copy_file
with bb_copyfd*
bb_copyfd is split into two functions bb_copyfd_size and bb_copyfd_eof,
they share a common backend.
