But don't change the way we process/store transactions and blocks. Effectively
it's just an interface for smart contracts that replaces old syscalls.
Transaction definition is moved temporarily to runtime package and Block
definition is removed (till we solve #1691 properly).
VM types are used in debugger, while smartcontract ones are used in
manifest. We can't save only one of them, because conversion in either
side is lossy:
1. VM has `Array` and `Struct` but smartcontract only has `Array`.
2. Smartcontract has `Hash160` etc, which are all `ByteString` or
`Buffer` in VM.
And to spice things a bit more, return type in debugger can be `Void`,
which corresponds to no real stackitem type (as it must exist).
For proper NEO3 debugger work we should provide namespaces for events
names in .debug.json files. But we don't have namespaces in .yml
configuration files and don't need this information for .manifest.json
generation, so let's just keep namespaces empty. This do not prevents
debugger from accepting our .debug.json files.
We currently can't process events in codegen, so we have to provide
them via .yml config file. Do not delete the rest of the code connected
with conversion of MethodDebugInfo.Event into manifest.Event as we have
issue #1038.
Function name now consists of 3 parts:
1) full package path
2) method receiver type (if any)
3) function name itself .
Fix#1150.

Invoke `_initialize` method on every call if present.
In NEO3 there is no entrypoint and methods are invoked by offset,
thus `Main` function is no longer required.
We still have special `Main` method in tests to simplify them.
Add ability to generate NEO3-compatable *.manifest.json into compiler.
This file represets contract manifest and includes ABI information, so
we don't need to create separate *.abi.json file. NEO3 debugger also
needs *.manifest.json only. So, switched from *.abi.json to
*.manifest.json file.
1. Slot is a new mechanism for storing variables during execution
which is more convenient than alt.stack. This commit implements
support for slot opcodes in both vm and compiler.
2. Remove old alt.stack opcodes.
3. Do not process globals at the start of every function, but instead
load them single time at main.
A part of integration with NEO Blockchain Toolkit (see #902). To be
able to deploy smart-contract compiled with neo-go compiler via NEO
Express, we have to generate additional .abi.json file. This file
contains the following information:
- hash of the compiled contract
- smart-contract metadata (title, description, version, author,
email, has-storage, has-dynamic-invoke, is-payable)
- smart-contract entry point
- functions
- events
However, this .abi.json file is slightly different from the one,
described in manifest.go, so we have to add auxilaury stractures for
json marshalling. The .abi.json format used by NEO-Express is described
[here](https://github.com/neo-project/neo-devpack-dotnet/blob/master/src/Neo.Compiler.MSIL/FuncExport.cs#L66).
Method `methodInfoFromScope(...)` always returned an empty parameters
set, so we were missing this information in both .abi.json and
.debug.json files. Fixed now.
Sequence points is a way to map a specific instruction offset
from a compiled contract to a text span in a source file.
This commit implements mapping only for `return` statements.
Further improvements are straight-forward.
