76f11310df sim: bpf: include more local headers & fix broken funcs
Various files were not including the relevant headers, or some funcs
were missing prototypes entirely, leading to mismatch between the
actual definition of the functions.  Add includes to a few places and
fix the broken functions that are uncovered as a result.  Fixing some
compile warnings (e.g. missing prototypes) often find real bugs.

0316fb52d6 bpf: several small fixes in the simulator
This patch fixes the following problems:
- Missing includes in several files leading to implicit function
  declarations.
- Missing prototype for bpf_trace_printk in bpf-helpers.h
- The simulator bitsize was set to 32 bits, causing truncation of
  the program counter.

Tested in bpf-unknown-none.
