135155a836 build: align wording of non-support reasons
Reasons for building not supported generally start with lowercase
because printed as the second part of a line.

Other changes:
	- "linux" should be "Linux" with a capital letter.
	- ARCH_X86_64 may be simply x86_64.
	- aarch64 is preferred over arm64.

b287267d62 event/dlb: add token pop API
The PMD uses a public interface to allow applications to
control the token pop mode. Supported token pop modes are
as follows, and they impact core scheduling affinity for
ldb ports.

AUTO_POP: Pop the CQ tokens immediately after dequeueing.
DELAYED_POP: Pop CQ tokens after (dequeue_depth - 1) events
	     are released. Supported on load-balanced ports
	     only.
DEFERRED_POP: Pop the CQ tokens during next dequeue operation.

02ce8e8837 event/dlb: add flexible interface
This commit introduces the flexible interface. This
interface allows the core code to operate in PF mode (direct
hardware access) or bifurcated mode (hardware configured via
kernel driver). This driver currently only supports PF modei,
but bifurcated mode will be added in a future patch-set.
Note that the flexible interface is not used for data path
operations, and thus there are no performance concerns
related to the use of function pointers.

218be03459 event/dlb: add documentation and build infrastructure
Note that config/rte_config.h contains several configuration
switches, providing for fine control of the PMD's
runtime behaviour.

The meson infrastructure is expanded as additional files are
added to this patchset.

Adds announcement of availability of the new driver
for Intel Dynamic Load Balancer 1.0 hardware.
