eventdev: add buffered enqueue and flush APIs
lib/librte_eventdev/rte_eventdev.c | 29 ++
lib/librte_eventdev/rte_eventdev.h
This commit adds buffered enqueue functionality to the eventdev API.
It is conceptually similar to the ethdev API's tx buffering, however
with a smaller API surface and no dropping of events.

I'm moving on to a new position in November and won't be able to continue
as a stack library maintainer.
Thanks to fellow maintainer Olivier, and the rest of the DPDK community,
for the support over the past few years.

When using the compiler to link libraries, include EXTRA_CFLAGS. This is
needed when cross-compiling to pass --sysroot, for example. GCC
cross-compilers built with Yocto don't use the --with-sysroot option,
making it necessary to pass the --sysroot command-line option.
This is the same solution as
ution as in commit e8fbb6d9cfd9 ("mk: use extra cflags
when linking with compiler"), but applied to libs instead of apps.

The linked list elements themselves are maintained in a non-blocking LIFO,
and are allocated before stack pushes and freed after stack pops. Since the
stack has a fixed maximum depth, these elements do not need to be
dynamically created.

This commit adds non-blocking stack variants of stack_autotest
(stack_nb_autotest) and stack_perf_autotest (stack_nb_perf_autotest),
which differ only in that the non-blocking versions pass the STACK_F_NB
flag to all rte_stack_create() calls.

This patchset is the successor to a patchset containing only the new mempool
