[iot-pmc] Californium - Milestone 1 for upcoming 3.0.0

["Kraus Achim (IOC/PAP-DDM-HU)" <Achim.Kraus@xxxxxxxx>]

Dear Californians,

the first milestone for the upcoming version 3.0.0 is released and available at the Eclipse Repo and on Maven Central.

The list of changes is long ...

Overall:
617 files changed, 28271 insertions(+), 22460 deletions(-)
Element-Connector:
68 files changed, 5123 insertions(+), 1322 deletions(-)
Scandium:
179 files changed, 7815 insertions(+), 9494 deletions(-)
Californium-Core:
130 files changed, 5895 insertions(+), 3659 deletions(-)

Generally, a lot of time was spent into tests, but with that amount of changes, I guess, some issues are still to be found.

The covered topics:

-    more cleanup of Scandium
-    RFC 7627 (extended master secret)
-    RFC 7967 (no response)
-    session cache
-    DTLS graceful start over
-    integrate BERT (TCP) into blockwise, redesigned bockwise
-    redesigned congestion control (still experimental)

Some topics are still uncovered, I hope I find some time at least after the 3.0.0-M1

-    Redesign NetworkConfig (Please participate in the discussion [7]
-    update proxy2 to Apache HTTP 5. (on the way, may be available next week)
