a script as a JMP instruction irregardless of whether it is

094c8474b7 compiler: move tests from vm/tests 
These don't belong to VM as they compile some Go code and run it in a VM. One
may call them integration tests, but I prefer to attribute them to
compiler. Moving these tests into pkg/compiler also allows to properly count
the compiler coverage they add:

-ok     github.com/CityOfZion/neo-go/pkg/compiler       (cached)        coverage: 69.7% of statements
+ok     github.com/CityOfZion/neo-go/pkg/compiler       (cached)        coverage: 84.2% of statements

This change also fixes `contant` typo and removes fake packages exposed to the
public by moving foo/bar/foobar into the testdata directory.

a7457d08a1 vm/core: add ID support for SYSCALL, redo interop registration 
This solves two problems:
 * adds support for shortened SYSCALL form that uses IDs (similar to #434, but
   for NEO 2.0, supporting both forms), which is important for compatibility
   with C# node and mainnet chain that uses it from some height
 * reworks interop plugging to use callbacks rather than appending to the map,
   these map mangling functions are clearly visible in the VM profiling
   statistics and we want spawning a VM to be fast, so it makes sense
   optimizing it. This change moves most of the work to the init() phase
   making VM setup cheaper.

Caveats:
 * InteropNameToID accepts `[]byte` because that's the thing we have in
   SYSCALL processing and that's the most often usecase for it, it leads to
   some conversions in other places but that's acceptable because those are
   either tests or init()
 * three getInterop functions are: `getDefaultVMInterop`, `getSystemInterop`
   and `getNeoInterop`

Our 100K (1.4M->1.5M) block import time improves by ~4% with this change.

54d888ba70 io: add type-specific read/write methods

 * uses fast ReadBytes everywhere it's appropriate

It also makes Fixed8 Serializable just for convenience.

d0f9a28196 vm/core: improve block import speed with PublicKey caching 
This change (closely related to the neo-project/neo#1321 proposal) speeds up
1.4M mainnet blocks import by 30%. Basically, we're eliminating key decoding
for block's multisignature that has the same keys most of the time.

Things I don't like about this patch:
 * yet another parameter for verifyHashAgainstScript()
 * vm keys are not copied in/out

But it's rather simple and solves the problem for this particular case, so I
think it's worth it.

And yes, they're opcodes because an instruction is a whole thing with
operands, that's what context.Next() returns.

e319c6c638 cli: move avm inspect from vm to contract command 
Make inspect work with avms by default and with go files if told so. In the
end this makes our CLI interface more consistent and usable. Drop useless
CompileAndInspect() compiler method along the way.

b2609786e9 vm: copy slice in NEWARRAY/NEWSTRUCT 
When performing NEWARRAY on a Struct or NEWSTRUCT on a Array,
underlying slice needs to be copied, because when it's capacity
doesn't matches it's length, underlying storage will be used
for appends even if it is already pointed at by another slice.

1bf232ad50 vm: introduce TryBool() for Element and use it in VerifyWitnesses 
Script can return non-bool results that can still be converted to bool
according to the usual VM rules. Unfortunately Bool() panics if this
conversion fails which is OK for things done in vm.execute(), but certainly
not for VerifyWitnesses(), thus there is a need for TryBool() that will just
return an error in this case.

d62a367900 vm: add Value() method to Element

428e789ddc vm: produce better error for ROLL with wrong index 
Current VM implementation doesn't return errors for many operations, so the
only way to handle it here is to check for NULL. Refs. #96.

ec7e17ffa6 pkg: make use of the new crypto/hash package 
Simplifies a lot of code and removes some duplication. Unfortunately I had to
move test_util random functions in same commit to avoid cycle
dependencies. One of these random functions was also used in core/transaction
testing, to simplify things I've just dropped it there and used a static
string (which is nice to have for a test anyway).

There is still sha256 left in wallet (but it needs to pass Hash structure into
the signing function).

4ccda04eea compiler: fix string/numbers equality/inequality gen again 
Unfortunately d58fbe0c88 didn't really fix the
problem because tinfo.Type (the expression resulting type) actually is a bool
and we need to check its parameters. Also, there is need to fix the NEQ
operation.

a1e3655560 interop: move into pkg/interop, replace pkg/vm/api 
neo-storm has developed more wrappers for syscall APIs, so they can and should
be used as a drop-in replacement for pkg/vm/api. Moving it out of vm, as it's
not exactly related to the VM itself.

7cd91610df compiler: quick and dirty inspection fix for JMP instrs 
These were interpreted completely wrong, they actually have two next bytes
indicating an offset. This patch is a quick fix, actually more work is needed
here to properly display various instructions.

810f096811 compiler: change codegen to emit NUMEQUAL instead of EQUAL 
This is wrong, see issue #294, but it makes our VM tests work (as VM is
missing EQUAL implementation), so until #294 is properly resolved we're better
have this kind of wrong code generation.
