usbip: tools: add more error codes for usbip request/reply messages

Browse Source 
Currently ST_OK and ST_NA are the only values defined to communicate
status of a request from a client. Add more error codes to clearly
indicate what failed. For example, when client sends request to import
a device that isn't export-able, server can send a specific error code
to the client.

Existing defines are moved to a common header in libsrc to be included
in the libusbip_la-usbip_common.o to be used by all the usbip tools.
Supporting interface to print error strings is added to the common lib.
