[PATCH v3 0/6] bpf: simple tests and fixes

[Marat Khalili]

Add simple unit-style tests for rte_bpf_load, and fix some minor
discovered bugs.

v3:
* Fixed unfortunate typos in the last patch commit message.
* Marked all ARM opcodes with UINT32_C for clarity as suggested by
  Morten Brørup, in a separate commit.

v2:
* Moved new tests back into test_bpf.c
* Changed library macros RTE_SHIFT_VALxx to handle variable first
  arguments instead of introducing new macros.
* Added another test and fix, for conditional jump as first instruction.

Marat Khalili (6):
  eal: variable first arguments of RTE_SHIFT_VALxx
  bpf: fix signed shift overflows in ARM JIT
  bpf: mark ARM opcodes with UINT32_C
  bpf: disallow empty program
  bpf: make add/subtract one program validate
  bpf: fix BPF validation w/ conditional jump first
