lib: build with meson Add non-EAL libraries to DPDK build. The compat lib is a special case, along with the previously-added EAL, but all other libs can be build using the same set of commands, where the individual meson.build files only need to specify their dependencies, source files, header files and ABI versions.

build: detect and use libnuma DPDK has an optional dependency on libnuma, so manage that through the build system, by dynamically detecting the presence of the needed library and header files. Since this library is used by both EAL and vhost, check for the presence at the top level in the config directory.

vhost: add config flag for postcopy Postcopy live-migration features relies on userfaultfd, which was only introduced in kernel v4.3. This patch introduces a new define to allow building vhost library on kernels not supporting userfaultfd. With legacy build system, user has to explicitly set CONFIG_RTE_LIBRTE_VHOST_POSTCOPY to 'y'. With Meson build system, RTE_LIBRTE_VHOST_POSTCOPY gets automatically defined if userfaultfd kernel header is present.

vhost: support selective datapath This patch set introduces support for selective datapath in DPDK vhost-user lib. vDPA stands for vhost Data Path Acceleration. The idea is to support virtio ring compatible devices to serve virtio driver directly to enable datapath acceleration. A set of device ops is defined for device specific operations: a. get_queue_num: Called to get supported queue number of the device. b. get_features: Called to get supported features of the device. c. get_protocol_features: Called to get supported protocol features of the device. d. dev_conf: Called to configure the actual device when the virtio device becomes ready. e. dev_close: Called to close the actual device when the virtio device is stopped. f. set_vring_state: Called to change the state of the vring in the actual device when vring state changes. g. set_features: Called to set the negotiated features to device. h. migration_done: Called to allow the device to response to RARP sending. i. get_vfio_group_fd: Called to get the VFIO group fd of the device. j. get_vfio_device_fd: Called to get the VFIO device fd of the device. k. get_notify_area: Called to get the notify area info of the queue.
