This patch moves all GSM-specific definitions to include/osmocom/gsm.
Moreover, the headers in include/osmocore/ have been moved to
include/osmocom/core.
This has been proposed by Harald Welte and Sylvain Munaunt.
Tested with `make distcheck'.

It is easier from languages that dlopen libosmocore to have a function
to access this data than to poke at the bytes of the struct directly. Add
copyright for this method and the reset method I did earlier this year.
