osmo-tetra: Add DMO Code

Dear Osmocom Community, I currently writing my masterthesis about TETRA. For this, I am currently writing my master thesis on TETRA. For this the support of DMO is necessary. Another student had already implemented a rudimentary DMO receiver (based on the Osmocom code) in his thesis, which I now develop further. I would like to add this code to the Osmocom project as a new branch so that other people can participate. I was unsure, based on which branch I should develop the code, but I decide for the laforge / sq5bpf-rebase-20161218 branch, because this is most useful for my purpose. I hope this is okay and doesn't lead to chaos. When trying to create a new branch and commit this, however I get an error message: $ Git push origin jj / dmo Error: no DAV locking support at https://git.osmocom.org/osmo-tetra/ Fatal: git-http-push failed Error: Error sending some references to 'https://git.osmocom.org/osmo-tetra' Unfortunately, I have not found instructions, who is at Osmocom allowed to commit code or how the process works. Can you help me with this or send me a link, where I find the appropriate information? Best regards, Jannik
