This commit adds new rte_prefetchX_write() variants, that suggest to the

what the best implementation for this instruction is.
Three versions are provided, targeting the different levels of cache.

struct cmdline exposes platform-specific members it contains, most
notably struct termios that is only available on Unix. While ABI
considerations prevent from hinding the definition on already supported
platforms, struct cmdline is considered logically opaque from now on.
Add a deprecation notice targeted at 20.11.
* Remove tests checking struct cmdline content as meaningless.
* Fix missing cmdline_free() in unit test.
* Add cmdline_get_rdline() to access history buffer indirectly.
The new function is currently used only in tests.

Forward error correction (FEC) is a bit error correction mode.
It adds error correction information to data packets at the

to signals. This function can be enabled or disabled as required.

Rather than having the fence signalled via a flag on a descriptor - which
requires reading the docs to find out whether the flag needs to go on the
last descriptor before, or the first descriptor after the fence - we can
instead add a separate fence API call. This becomes unambiguous to use,
since the fence call explicitly comes between two other enqueue calls. It
also allows more freedom of implementation in the driver code.
