util-device: break into public and private definitions
util-device.h exposes some details that are particularly problematic for C++, even when wrapped in 'extern "C"'. To address this, break the header into public and private parts. The public part exposes LiveDevice as an opaque data structure, while the private header has the actual definition. The idea is that only Suricata C source files should include the private header, it should not be re-included in any other header file. And this is the header library users should use, however we don't enforce it with tecnical means, a library user could still include the private header, but the clue there is in the name.pull/13125/head
