bpf: add BPF loading and execution framework librte_bpf provides a framework to load and execute eBPF bytecode inside user-space dpdk based applications. It supports basic set of features from eBPF spec (https://www.kernel.org/doc/Documentation/networking/filter.txt). Not currently supported features: - JIT - cBPF - tail-pointer call - eBPF MAP - skb - function calls for 32-bit apps - mbuf pointer as input parameter for 32-bit apps Signed-off-by: Konstantin Ananyev <konstantin.ananyev@intel.com> Acked-by: Ferruh Yigit <ferruh.yigit@intel.com>

build: set RTE_ARCH_64 based on pointer size Rather than relying on the target machine architecture, use the size of a pointer from the compiler to determine if we are 64-bits or not. This allows correct behaviour when you pass -m32 as a compile option. It also allows us to use this value repeatedly throughout the repo rather than continually testing for the sizeof(void*).

build: improve dependency handling Whenever possible (if the library ships a pkg-config file) use meson's dependency() function to look for it, as it will automatically add it to the Requires.private list if needed, to allow for static builds to succeed for reverse dependencies of DPDK. Otherwise the recursive dependencies are not parsed, and users doing static builds have to resolve them manually by themselves. When using this API avoid additional checks that are superfluous and take extra time, and avoid adding the linker flag manually which causes it to be duplicated.

bpf: remove use of weak functions Weak functions don't work well with static libraries and require the use of "whole-archive" flag to ensure that the correct function is used when linking. Since the weak function is only used as a placeholder within this library alone, we can replace it with a non-weak version protected using preprocessor ifdefs.
