Updates

This update essentially contains 2 parts:
* misc build fixes and slight rearrangement of the CMakeLists.txt file
* change in handling of the machine file (regardless of local or remote addresses, it's now up to the client to check whether it needs to use the loopback address or not. All what's required is to enable the "SKV_ROQ_LOOPBACK_WORKAROUND" compile flag - this flag will be auto-enabled if the verbs implementation of the IT-API is selected)

The high number of changes is caused by moving it_api and fxlogger files for better installation paths of headers
