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.

mbuf: support dynamic fields and flags Many features require to store data inside the mbuf. As the room in mbuf structure is limited, it is not possible to have a field for each feature. Also, changing fields in the mbuf structure can break the API or ABI. This commit addresses these issues, by enabling the dynamic registration of fields or flags: - a dynamic field is a named area in the rte_mbuf structure, with a given size (>= 1 byte) and alignment constraint. - a dynamic flag is a named bit in the rte_mbuf structure. The typical use case is a PMD that registers space for an offload feature, when the application requests to enable this feature. As the space in mbuf is limited, the space should only be reserved if it is going to be used (i.e when the application explicitly asks for it). The registration can be done at any moment, but it is not possible to unregister fields or flags.

mbuf: move definitions into a separate file Right now inclusion of rte_mbuf.h header can cause inclusion of some arch/os specific headers. That prevents it to be included directly by some non-DPDK (but related) entities: KNI, BPF programs, etc. To overcome that problem usually a separate definitions of rte_mbuf structure is created within these entities. That aproach has a lot of drawbacks: code duplication, error prone, etc. This patch moves rte_mbuf structure definition (and some related macros) into a separate file that can be included by both rte_mbuf.h and other non-DPDK entities. Note that it doesn't introduce any change for current DPDK code.
