f068f4c0ed pkg/vm/stack: drop unused (*RandomAccess).items() 
GolangCI complains:
  U1000: func (*RandomAccess).items is unused

And it looks like everyone and their dog just use ras.vals without any
wrappers when there is a need to access it, so drop the wrapper.

1fb66d6b73 pkg/vm/stack: improve Array testing code slightly 
GolangCI complained:
  testArray is unused (from deadcode)

But this function was actually wrong being a copy-paste of testMakeStackMap(),
it also didn't conform to testMake... naming scheme, so this fixes it. To make
thing more uniform NewArray() was also changed to return error, map_test.go
code adjusted to this changes and finally array_test.go was added as a stub
for future Array testing.

06f9e1d123 pkg/(crypto|vm): fix GolangCI errcheck warnings 
Like:
  Error return value of alg.Write is not checked (from errcheck)

Actually even though the hash.Hash implements an io.Writer interface (that
return meaningful things on .Write()) it has this comment in its
documentation:

// Write (via the embedded io.Writer interface) adds more data to the running hash.
// It never returns an error.

so it should be OK to ignore return results here.
