5b8c89d1f2 build system: make CONFIG_FEATURE_USE_BSS_TAIL less funky
CONFIG_FEATURE_USE_BSS_TAIL code was aliasing bb_common_bufsiz1 to _end.
This is unreliable: _end may be not sufficiently aligned.

Change code to simply enlarge COMMON_BUFSIZE when we detect that _end
has significant amount of space to the end of page.

8f4faa1e3d df: use f_frsize instead of f_bsize for correct sizes
Use the correct field f_frsize instead of f_bsize.

The statfs f_bsize is the "Optimal transfer block size" while the
f_frsize is the "Fragment size (since Linux 2.6)". On some FUSE
filesystems those may differ.

Fixes bug 9046

59f8197624 i2cdump: don't use common_bufsiz1
Commit e6a2f4cc changed the way common_bufsiz1 works. Now it needs to
be initialized before using, but i2cdump wasn't updated by said patch.

Since the fact that we're using common_bufsiz1 here isn't obvious (no
G_INIT() macro, no other global variables), drop it and simply
allocate the integer array required for block reads on the stack.

Tested with i2c block read on a Lenovo Thinkpad laptop.

4d5acd2d42 ping: populate icmp_id field for "simple" ping too
The ICMP RFC says that identifier and sequence number may be zero.
Having them zero for a Echo message, along with a data of zero's
as well will result in a Echo reply message with only zero's.

Some NAT implementations seem to get the checksum wrong on these
packages. Setting a checksum of 0x0 instead of 0xffff.

Through NAT:
  Internet Control Message Protocol
      Type: 0 (Echo (ping) reply)
      Code: 0
      Checksum: 0x0000 [incorrect, should be 0xffff]
      Identifier (BE): 0 (0x0000)
      Identifier (LE): 0 (0x0000)
      Sequence number (BE): 0 (0x0000)
      Sequence number (LE): 0 (0x0000)
      Data (56 bytes)
          Data: 000000000000000000000000000000000000000000000000...
          [Length: 56]

Without NAT:
  Internet Control Message Protocol
      Type: 0 (Echo (ping) reply)
      Code: 0
      Checksum: 0xffff [correct]
      Identifier (BE): 0 (0x0000)
      Identifier (LE): 0 (0x0000)
      Sequence number (BE): 0 (0x0000)
      Sequence number (LE): 0 (0x0000)
      [Request frame: 189]
      [Response time: 0.024 ms]
      Data (56 bytes)
          Data: 000000000000000000000000000000000000000000000000...
          [Length: 56]

And this in turn will make some hardware MAC checksum offloading
engines drop the packet.

(This was seen with a Synopsis MAC, the same one used in for instance the
stmmac Ethernet driver in the linux kernel.)

This change can be seen as a workaround for bugs in other layers.
But just setting an identifier for the Echo message packet will
avoid prodding the hornets nest.

e4caf1dd9c ntpd: retry initial DNS resolution (forever, no timeout for now).
Some users start ntpd on boot, and don't babysit it. If it dies because
DNS is not yet up and therefore NTP servers can't be found, users are
not happy.

84ba50c32f ash: bash-compatible $'...' shouldn't expand in double quotes
Bash doesn't expand its $'...' construct in double quotes:

   $ echo "$'a\tb'"
   $'a\tb'

Change BusyBox ash to do the same.  This also fixes a problem with
here documents where BusyBox ash gave an incorrect result for:

   $ cat <<EOF
   > '$'
   > EOF
   '$'
