When running make menuconfig from /wr/etc, mconf was crashing when dialog box
in the style of radiolist was displayed and special keys (like arrow keys)
were pressed. Crash was due to assetion in function toupper from uClibc.
Function to upper should return unchanged value if passed parameter is not
alpha. However, uClibc's implementation behaves in the different way,
it asserts.
After assert following message was printed:
(./mconf: libc/misc/ctype/ctype.c: 320: toupper:
Assertion `((((unsigned int)((c) - 0)) <= ((127 * 2 + 1) - 0)) ||
((c) == (-1)))' failed.

Create script which can be filled with vlans' configuration

So far there are no VLANs configured in this script, but it is good start.
When one needs can populate this sctipt on his/her own.
NOTE: VLANs should be configured before any other traffic is allowed. This
is done by previous commits.

Set-up VLAN related registers during driver load instead of during opening
(bringing up) interfaces.
From now VLANs can be configured after loading the driver, but before bringing
up of interfaces. By this no switching is done without VLANs beeing configured.

Support assembling dot-config's URL from DHCP options:
--the filename
--the BOOTP next server option
In this case TFTP protocol is used. It is similar to the pxe booting.

Also update documentation.

Don't run DHCP's default script (/usr/share/udhcpc/default.script) when getting
URL to the dot-config via DHCP. When the script was run, then the IP address
was set but not the default routes. Now just get URL via DHCP, setting IP is
done by running script /etc/init.d/network from /etc/init.d/dot-config or from
rcS.

SNMPd bugfixes

t_n_rows (n_rows before) has to be local for table. Having it global sometimes
caused to print wrong number of rows in tables. This bug may even cause snmpd
to crash.
It was dependent on the call order of *_data_fill funtions.

Change the n_rows into t_n_rows, since the usage of n_rows variable is common
in the snmp code. By this avoid potential errors like variable overleaping
problems.

When wrsPTPStatus can only be updated when both ptp_data and spllStatus are
updated. Otherwise spllStatus changes may cause wrong delta calculation
in get_wrsPTPStatus function. In this case prev data is the same as current,
which may produce false error.

There was a bug in wrsTimingStatus_data_fill that even if not all of the
wrsPtpDataTable_data_fill, wrsSpllStatus_data_fill or
wrsPortStatusTable_data_fill were updated all objects in the
wrsTimingStatusGroup were updated. As a side effect it may happen that all
prev_ values were compared with exactly the same set of data (since there was
no update in particular data). By this delta were zero and wrong value was set.

The bug may be hit when snmp requests rate is lower than snmpd's cache timeout.
