60702e8c7c bpf: add extra information for external symbol definitions
Extend struct rte_bpf_xsym with new fields to provide information about:
 - for variables - type and size
 - for functions - number of arguments and type/size of each argument
   and return value

Such information would allow validate code to perform
more extensive checking on input BPF program and catch
misbehaving BPF code.

That change would cause ABI/API breakage for librte_bpf.

94972f35a0 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
