Store information about protocol, server IP and filename of retrived dotconfig.
Information is stored in:
-- /tmp/dot-config_proto
-- /tmp/dot-config_host
-- /tmp/dot-config_filename

When dotconfig is local don't store source information.
When web-interface changes dot-config, remove source information because after
changes configuration is stored locally.
This is going to be used by SNMP

Change order of including headers and init functions in init.c, additionally
change order of compilation in Makefile to reflect order in MIB.

No technical change.

Change location of branch wrSwitchMIB.wrsStatus from high number (256) to
low (6), then move wrSwitchMIB.wrsEpertStatus to (7).
At the beginning wrsStatus branch was placed at high number because objects
from that branch might use several other objects to calculate their own value.
For example, there was a risk that query of wrsMainSystemStatus triggers
cascade of time consuming cache fills and snmpget timeouts. However, practice
shown that cache filling is significantly shorter that SNMP transfers.
Additionally, such risk was possible in case of snmpwalk or other method
querying objects in order.

Second test of $? value was not always result of command
"tftp $eth0.ipaddr/wrboot wrboot", but sometimes result of first if statement
(in case first tftp was successful).

In other words, when there was file wrboot-$eth0.ethaddr on tftp server, script
was still fetching and executing wrboot.
