Add support for unique TFTP root per MAC.

Browse Source 
It is currently only possible to let the TFTP server serve a different
folder depending on the client's IP address.
However it isn't always possible to predict what the client's
IP address will be, especially in situations in which we are not
responsible for handing them out (e.g. proxy dhcp setups).

Extend the current --tftp-unique-root parameter to support having a
separate folder per MAC address instead.

.B --tftp-no-fail
Do not abort startup if specified tftp root directories are inaccessible.
.TP
.B --tftp-unique-root
Add the IP address of the TFTP client as a path component on the end
of the TFTP-root (in standard dotted-quad format). Only valid if a
tftp-root is set and the directory exists. For instance, if tftp-root is "/tftp" and client
1.2.3.4 requests file "myfile" then the effective path will be
"/tftp/1.2.3.4/myfile" if /tftp/1.2.3.4 exists or /tftp/myfile otherwise.
.B --tftp-unique-root[=ip|mac]
Add the IP or hardware address of the TFTP client as a path component on the end
of the TFTP-root. Only valid if a tftp-root is set and the directory exists.
Defaults to adding IP address (in standard dotted-quad format).
For instance, if tftp-root is "/tftp" and client 1.2.3.4 requests file "myfile"
then the effective path will be "/tftp/1.2.3.4/myfile" if /tftp/1.2.3.4 exists or /tftp/myfile otherwise.
When "=mac" is specified it will append the MAC address instead, using lowercase zero padded digits
separated by dashes, e.g.: 01-02-03-04-aa-bb
Note that resolving MAC addresses is only possible if the client is in the local network or obtained
a DHCP lease from us.
