This patch set make DPDK library, driver, and application code
optionally use the compiler/libc memcpy() when functions in
<rte_memcpy.h> are invoked.

The new compiler memcpy-based rte_memcpy() implementations may be
enabled by means of a build-time option.

This patch set only make a difference on x86, PPC and ARM. Loongarch
and RISCV already used compiler/libc memcpy().

This patch set includes a number of fixes in drivers and libraries
which errornously relied on <rte_memcpy.h> including header files
(i.e., <rte_vect.h>) required by its implementation.

Mattias Rönnblom (7):
  event/dlb2: include headers for vector and memory copy APIs
  net/octeon_ep: add missing vector API header include
  distributor: add missing vector API header include
  fib: add missing vector API header include
  eal: provide option to use compiler memcpy instead of RTE
  ci: test compiler memcpy
  vhost: optimize memcpy routines when cc memcpy is used
