54dcfdee85 drivers/raw: standardize naming
The driver names for rawdevs were both different in make and meson builds
and were non-standard in the make version in that some included "rawdev" in
the name while others didn't.

Therefore, for global consistency of naming, we can use "rte_rawdev" rather
than "rte_pmd" for the prefix for the libraries. While most other driver
categories use "rte_pmd" as a prefix, there is precedent for this in the
mempool drivers use "rte_mempool" as a prefix.

c5eebf85ba examples/ntb: add example for NTB
Enable an example for rawdev ntb. Support interactive mode to send
file on one host and receive file from another host. The command line
would be 'send [filepath]' and 'receive [filepath]'.

But since the FIFO is not enabled right now, use rte_memcpy as the enqueue
and dequeue functions and only support transmitting file no more than 4M.
