[Pianod] Missing fgetln, Makefiles, svn versus latest, commands

[Peter Li]

Hey, thanks for your work on this; seems to work pretty nicely.

I had a few problems with building on ArchLinuxARM (RPi).  The main 
thing is that the version from SVN is missing fgetln.h and fgetln.c in 
libfootball.  I had to copy those over from latest to get it to build 
with NEED_FGETLN=1.

On latest, this wasn't an issue because I have libbsd installed.  So it 
just linked against libbsd and didn't NEED_FGETLN.  Would be nice if SVN 
version did this too by default.

Maybe you could explain a little bit the difference between the SVN and 
latest versions; seems kind of weird to me that they are so different.

I also note that a few commands don't seem to be implemented, notably 
"stop" and "shutdown" both reply with 200 but don't appear to do 
anything.  Is that expected?

I also had one instance in a few hours usage where the TLS handshake 
failed for no clear reason.  Just restarting the station worked.

Like I said, it's all working pretty nicely so these are just little things.
Best,
P
