first version of OMS based meter support

[mbehr1]

As discussed in #176 see here the first version.
Thanks to @schnello for support with infos and debug host.

Currently only 4 Obis values are supported: 1.7.0, 2.7.0, 1.8.0 and 2.8.0.

For configuration use conf editor or

{
"protocol":  "oms",
"device": "/dev/ttyUSB0",
"key": "<32char AES key in hex without spaces>"
"channel": { "uuid": "...", "identifier": "1.7.0" }
}

.
Currently only serial/tty devices and encryption mode 5 is supported.

Please don't use interval but use aggregation to reduce data rate if needed/wanted.

It requires openssl and libmbus >=0.8.0 from e.g. https://github.com/rscada/libmbus.git
(installation is easy:

git clone https://github.com/rscada/libmbus.git
cd libmbus
./build.sh
make install

Please test and let me know any feedback.

I fixed a hang on program termination (in non daemon mode after pressing ctrl-c) that was introduced with push data but found during tests here (thanks to @schnello).
Dumped version to 0.4.3. to reflect support of new meter.

Do we need libmbus support in install.sh?

[mbehr1]

Would make sense (but otherwise build process will be ok but just with OMS support). Can you add it? Needed steps see above (git clone ..., ./build.sh make install)

[andig]

Can you add it?

Glad to. I'll merge first and add install.sh then, ok?

[mbehr1]

sure

[andig]

We're also missing a config example? I'll add one later on. Json editor should not be missed.

[mbehr1]

I’ll add one. Had it in the first version but needed to remove as otherwise tests fail without libmbus…

+1 for merging this pr. libmbus is merged.

[UdoSchake]

What abt. openssl? Don't we need it too?

[mbehr1]

openssl is already part for SML based readers.

[mbehr1]

But there is one issue with the timestamps under investigation. I wait for merge until that's sorted out.

Really? I dont find it in the dependencies of vzlogger, libsml or middleware.

[mbehr1]

sorry. is needed for mysmartgrid not for SML
excerpt from CMakeList.txt

 include(FindGnutls)
  include(FindOpenSSL) # needed by MySmartGrid API...

[mbehr1]

Still ok for merge? I added conf file and fixed the timestamp issue reported from @schnello.

[mbehr1]

Still one issue with timestamps (devices seems to send packets with duplicate ones). I'll add a workaround.

[mbehr1]

I'll merge now so that we might get more people to test it. Different meters than the one from @schnello will most likely show new effects. Just let me know in case of any problems.
