80f0f1d712 setfiles: switch bb_info_msg to printf 
Presumably, bb_info_msg was used here for syslog logging (-l),
but there is no actual code to activate syslog logging.
Added a TODO note on that, so that selinux users would notice
and fix if needed.

610c4c385b applet_tables: save space by removing applet name offsets 
The array applet_nameofs consumes two bytes per applet.  It encodes

   nofork/noexec flags
   suid flags
   the offset of the applet name in the applet_name string

Change the applet_table build tool to store the flags in two separate
arrays (applet_flags and applet_suid).  Replace applet_nameofs[] with a
smaller version that only stores a limited number of offsets.

This requires changes to the macros APPLET_IS_NOFORK, APPLET_IS_NOEXEC
and APPLET_SUID.

   According to Valgrind the original find_applet_by_name required
   353 cycles per call, averaged over all names.  Adjusting the number
   of known offsets allows space to be traded off against execution time:

      KNOWN_OFFSETS     cycles     bytes (wrt KNOWN_OFFSETS = 0)

           0             9057        -
           2             4604       32
           4             2407       75
           8             1342       98
          16              908      130
          32              884      194

   This patch uses KNOWN_OFFSETS = 8.

v2:
   Remove some dead code from the applet_table tool;
   Treat the applet in the middle of the table as a special case.

v3:
   Use the middle applet to adjust the start of the linear search as
   well as the last applet found.

v4:
   Use an augmented linear search in find_applet_by_name.
   Drop the special treatment of the middle name from get_applet_name:
   most of the advantage now derives from the last stored value.

v5:
   Don't store index in applet_nameofs, it can be calculated.

v6:

3e3bfb896e ash: fix corruption of ${#var} if $var contains UTF-8 characters 
As reported in bug 8506:

   $ X=abcdÉfghÍjklmnÓpqrstÚvwcyz
   $ echo ${#X}
   abcd26

The result should be 26.

This regression was introduced by:

   <d68d1fb> 2015-05-18 [Ron Yorston]  ash: code shrink around varvalue

The length in characters was being used to discard the contents of
the variable instead of the length in bytes.

ea351b9742 ls: fix columnar output. Closes 8731 
In coreutils/ls.c, 1.19 introduced commit
2f7d9e8903, removing the variable tabstops and
hard coding the column separation to 2 characters, but was not done correctly.
The column_width assumes a gap of 1 character, so the computed number of
columns exceeds the terminal width when many small files are encountered.

A minor problem but surprisingly annoying.

abe8f7515a dhcpc: Use client IP address as source address for DHCP renew/rebind messages 
RFC2131 paragraph 4.1 states DHCP messages broadcast by a client prior to
that client obtaining its IP address must have the source IP address
field in the header set to 0.
Request messages transmitted in renewing and rebinding state need to use
the obtained IP address as source IP address in the header; this behavior
lines up with other implementations like ISC dhcp client.
