This commit enables colors in bmon. It adds configuration options to
let the user decide, which colors should be used. Therefor the graph_rx and graph_tx
layouts are introduced and applied respectively.
* Add graph_rx, graph_tx and layout_cfg fields.
* Setting default colors if colorized output is enabled.
* draw_table accept additional layout parameter and apply the given layout for
the table graph.
* Apply layouts for rx, tx graph and header and statusbar.
* Add include/layout.h, which provides functions to parse, color and attribute
strings and set the layout.
* Adding a default layout-config example in examples/bmon.conf.

When compiling bmon with gcc 6.1 it complains with the following
warning:
out_format.c: In function ‘get_token’:
out_format.c:134:10: warning: this ‘if’ clause does not guard... [-Wmisleading-indentation]
} else if (!strncasecmp(token+5, "txrate:", 7))
^~
out_format.c:136:4: note: ...this statement, but the latter is misleadingly indented as if it is guarded by the ‘if’
return buf;
^~~~~~
Indeed, the 'return buf' should only be executed if it was snprintf()'ed
to. Otherwise "unknown" should be returned. Fix this by adding braces.
Also use the 'type' variable in strncasecmp() as in the other checks.

Press 'r' in curses mode to reset a statistic counter to
start counting from 0 again. This does NOT reset the
counter from the source itself but merely emulates a
counter reset. If you restart bmon, the counter will be
back to its total value.

The qdisc cache is host wide, the parent classid is not unique
so the ifindex of the parent tc object must be set in the filter
otherwise a leaf qdisc with an identical parent id in another
device can be mistaken.
This also converts the class_cache to be passed up through the
stack to make clear it is not system wide but specific to the
ifindex we are currently handling.

Hook up additional IPv6 link statistics counters available since libnl
v3.2.25. Also add compatibility defines, so bmon can still be compiled
against older libnl versions.

Up to now, the entire Netlink module was disable if QoS statistics were
not available. Merely disable TC stats themselves but continue using
the input module.

When compiling bmon with the Linaro 2014.01 ARM toolchain
(gcc-linaro-arm-linux-gnueabihf-4.8-2014.01_linux) the following compile error occurs:
in_netlink.c: In function ‘do_link’:
in_netlink.c:688:53: error: ‘IFF_UP’ undeclared (first use in this function)
Fix it by explicitly including linux/if.h, where IFF_UP is defined.
