We are currently using the include path used when building DPDK, however
when installing DPDK, the headers are put in ${prefix}/include/dpdk.
We should use the latter in our include path.

build: make so numbering to be tied to ODP versions
We do not make any promises on ABI backwards compatibility, we have been
using -version-number instead of -version-info for ages, so affirm this
approach. Drop misleading comment and tie SO version numbers to ODP
relase numbers.

linux-gen: sched: optimize parallel packet input queue throughput
Extend direct packet input processing to parallel queues. Parallel
queues do not quarantee ordering, so also those can pass packets
directly to application and (potentially) stash some per thread.

linux-gen: sched: optimize atomic packet input queue throughput
When packet input queue is atomic, packets received from packet
input are passed directly to the application. Other queue types
may have events stashed on other threads, so for those incoming
packets are always enqueued (to maintain packet order).

commit 3e61be54a77ed8ccc2030e88b9a26372d3f76e2c

linux-gen: sched: optimize packet input polling
Optimize scheduler throughput with packet IO interfaces.
Special pktio poll commands are removed and event queue is
used instead to trigger packet input polling. Packet input is
polled when those queues are empty. Thus, these queues
connected to packet input are not removed from scheduling
when empty.

validation: pktio: remove pktio_test_send_failure test
pktio_test_send_failure() tries to transmit a packet which is larger
than odp_pktout_maxlen. ODP API doesn't guarantee what happens when one
tries to send an oversized packet, so remove the test.

linux-gen: add runtime configuration file
Enables changing ODP runtime configuration options by using an optional
configuration file (libconfig). Path to the conf file is passed using
environment variable ODP_CONF_FILE. If ODP_CONF_FILE or a particular option
is not set, hardcoded default values are used instead. An template
configuration file is provided in config/odp-linux.conf.
Runtime configuration is initially used by DPDK pktio to set NIC options.
Adds new dependency to libconfig library.

ODP configuration options
-------------------------
+
+Runtime configuration options can be passed to an ODP instance by
+setting ODP_CONFIG_FILE environment variable to point to a libconfig
+format configuration file. A template configuration file with default
+values is provided in config/odp-linux-generic.conf. The values set in
+config/odp-linux-generic.conf are hardcoded during configure/build
+phase. If ODP_CONFIG_FILE is not set at runtime, hardcoded default
+values are used instead of any configuration file. A configuration file
+passed using ODP_CONFIG_FILE doesn't have to include all available
+options. The missing options are replaced with hardcoded default values.

This update added new revisions after undoing existing revisions. That is
to say, the old revision is not a strict subset of the new revision. This
situation occurs when you --force push a change and generate a repository
containing something like this:
* -- * -- B -- O -- O -- O (89f735041d4474f5da399ff683200991fc73cdd9)
\
N -- N -- N (f3cf9c3583364af7625679d0021c4d55c3414994)
When this happens we assume that you've already had alert emails for all
of the O revisions, and so we here report only the revisions in the N
branch from the common base, B.
Those revisions listed above that are new to this repository have
not appeared on any other notification email; so we list those
revisions in full, below.
