We had some inconsistencies between functions prototypes and actual
definitions.
Let's avoid this by only adding the experimental tag to the prototypes.
Tests with gcc and clang show it is enough.

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.

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.

Introduce rte_bpf_elf_load() function to provide ability to
load eBPF program from ELF object file.
It also adds dependency on libelf.

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
