configure: Make use of ncurses configurable
When ncurses is found the current build system will use it to build the
"noping" utility. However, that will create an automagic dependencies on
ncurses which is a problem for some distributions.
This commit adds the ability to control the ncurses usage:
a) If the user calls "configure" like before nothing changes: Configure
tries to find a suitable ncurses installation to build "noping". If
not found build system will just skip building of "noping" utility.
b) If the user calls "configure" with new "--with-ncurses" option,
configure will now fail if no suitable ncurses installation was
found.
c) If the user calls "configure" with new "--without-ncurses" option, the
build system will now skip building of "noping" utility and ncurses
will not be used.
In addition, this commit also changes the way configure will detect
ncurses: Configure now tries to use pkg-config to find ncurses but still
falls back to previous legacy checks. This will add support for ncurses
installation built with "--with-termlib" which causes several symbols to
get moved from libncurses.so to libtinfo.so.

add bell output on successful pings
the rationale here is that it's actually pretty hard to do this with a
regular ping. you need a silly shell loop and it doesn't always work
right everywhere, because the output of the system ping is
platform-dependant. it also buffers stdout in some weird ways sometimes.
therefore, i think it's a great addition to oping.
the purpose of this is that it can be useful to "hear" ping packets
come back when doing network diagnostics. obviously, this will be
useless in finding out *failed* hosts if multiple hosts are selected,
as any sucessful host will produce a beep. but it can nevertheless be
used to trace network cables or problems without looking at the
console. i also use audible pings to let me know when a hosts returns
after a reboot.
Note that I had to struggle quite a bit to make my terminal bell work,
the following articles were used to generate documentation on how to
make that work reliably:

add autogen script for clueless people like me
implement some prettyping-inspired display instead of textual
this is a first stab at porting "prettyping.sh" into noping. the idea
is to show a histogram of ping times instead of numerical values. with
some work, we could actually show both, but this focuses on
implementing the hard part (the histogram) properly.
it is very rudimentary for now:
* the math may be wrong for the size of the bar, I was mostly in a
rush to make unicode work and have something pretty quickly.
* all hosts are on the same line: each should have its own line
* the histogram should be displayed in a separate window
* it should use background colors as well
* it should fallback when the terminal is not unicode-capable
* the scaling logic is fully automatic, which necessarily gives weird
results at first
this requires switching to the ncursesw library and other unicode

Bump ABI version; update ChangeLog.
Mac OX S 10.7 compile fixes.
I've attached a patch that's required to be able to compile liboping on
MacOS 10.7 (Lion). The issue is that the IPv6 API's are changing from
RFC 2292 to 3542, and Apple's headers require you to state which API you
want to use by defining a constant. I've changed it to use either based
on the presence of constants, but to prefer 3542 on MacOS.
One problem I see with this is that if you have both multicast and
unicast TTL's set, then this won't report both of them, but I'm not sure
if that's even valid and it would require more significant rework.
Also, I noticed you have fixed the IP_RECVTOS issue in head. That patch
is also required to be able to compile on Solaris and MacOS.

oping: Make the exit status the number of hosts failed.
As far as I know, EXIT_FAILURE is only portable when used as-is, i.e. without
adding anything to it. Especially with "EXIT_FAILURE == -1" we might run into
trouble. I think it's more convenient to just use the number of failed hosts
rather than 1+<num> (on Linux).
