a84db18fc7 tar,unzip: postpone creation of symlinks with "suspicious" targets 
This mostly reverts commit bc9bbeb2b8
"libarchive: do not extract unsafe symlinks unless $EXTRACT_UNSAFE_SYMLINKS=1"

Users report that it is somewhat too restrictive. See
https://bugs.busybox.net/show_bug.cgi?id=8411

In particular, this interferes with unpacking of busybox-based
filesystems with links like "sbin/applet" -> "../bin/busybox".

The change is made smaller by deleting ARCHIVE_EXTRACT_QUIET flag -
it is unused since 2010, and removing conditionals on it
allows commonalizing some error message codes.

ecaec1dbec testsuite: update busybox and bzcat tests 
Test scripts that use CONFIG_* variables need to source .config.
Since this wasn't being done for busybox many tests were skipped.
As a result new failures due to changes in help output were missed.

Also remove some unnecessary echos in the bzcat script.

a165603d24 od_bloaty: fix floating point output 
Currently od_bloaty does this:

   $ /bin/echo -en '\x00\x00\x00\x00\x00\x00\x00\x00' | busybox od -f
   od: invalid character 'F' in type string 'fF'
   $ /bin/echo -en '\x00\x00\x00\x00\x00\x00\x00\x00' | busybox od -t fD
   od: invalid character 'D' in type string 'fD'
   $ /bin/echo -en '\x00\x00\x00\x00\x00\x00\x00\x00' | busybox od -t f
   0000000
   0000010

The first two occur because the alphabetic length specifier isn't being
properly skipped.  The third is due to the empty length specifier being
treated as alphabetic so we fall off the end of the FDL_sizeof array with
undetermined consequences.  Coreutils defaults to printing a double in
this case.

With this patch the output is:

   $ /bin/echo -en '\x00\x00\x00\x00\x00\x00\x00\x00' | ./busybox od -f
   0000000   0.0000000e+00   0.0000000e+00
   0000010
   $ /bin/echo -en '\x00\x00\x00\x00\x00\x00\x00\x00' | ./busybox od -t fD
   0000000   0.000000000000000e+00
   0000010
   $ /bin/echo -en '\x00\x00\x00\x00\x00\x00\x00\x00' | ./busybox od -t f
   0000000   0.000000000000000e+00
   0000010

I guess nobody uses BusyBox od to print floating point numbers.
