This moves wr to usr/wr and copies etc to usr/etc.
Also, it creates the .tar.gz for /usr and an initramfs
that excludes usr.

The current installation still works (it ignores new files,
and can live with wr pointing to usr/wr).

This changes partitions, mainly adding a kernel-visible mapping of
what we ha in dataflash.  NAND changes are compatible, as only empty
space is used differently.

This also includes a new barebox.bin, that you can just write
to /dev/mtd3 after booting the new kernel.

Documentation is updated to reflect these partitions, but there also
old leftovers that are fixed in this same commit.

3 are not enough: we need 4. So support up to 16 even though we waste
a few dozen bytes of precious RAM.

dirname() and basename() change their argument.  We'd better
strdup(argv[0]) to be able to use it in error messages.

In our case the name of the switch is its IP address of eth0 interface. Without
this option enabled, only the first octet is reported to remote log server (e.g.
192)

They disappeared quite some time ago: only .tar.gz remains.  Fix
documentation accordingly.

Some WRS speciments won't work correctly with automatic speed setup.
This patch forces full-speed on the device (instead of the
autodetected high-speed), and thus they work.

Speed is not a problem anyways, because it is just a serial port.

wr_nic now exports wr_nic_pstats_callback as a pointer. When wr_pstats
is loaded it writes its own pointer in there.

wr_nic can thus ask for statistics and updated net_device_stats with
the proper numbers.   The statistics on snmp reflect this, because
snmpd uses the standard device ioctl commands -- but very few of our
counters actually end up all the way to snmp.

Stuff was seriously misaligned and hard to read. So Maciej agreed
about running ../../scripts/Lindent. This commit makes no modification
at all, even it changes both spaces/tabs and newlines.

Some comments still exceed 80 columns, which is bad for me, my screen and
my printer, but I'll only change if needed, at a later step.

Since there is no env config file, envfs_check_super() call fails to find
correct magic number and makes envfs_load function to return before setting
default MAC addresses.

  * MAXPORTS is NPORTS (so to use the usual C convention

PSTATS_NPORTS in the kernel driver should be set by default to 18 ports, because
it's also used to create a table for cntrs values read from FPGA. If driver is
supposed to run on 8-port version of WRS, the parameter pstats_nports should be
set at load time.
