2b73508561 compiler: emit short jumps while short-circuiting
Unless there is some `ast.Walk` between current instruction and jump
target, we can calculate the offset precisely.

984aba3113 compiler: process last instructin in writeJumps
It is unlikely that we will emit a script with a JMP in the end,
but `writeJumps` must work correctly even in such case.

cfa62e7051 compiler: emit short jumps where possible
Convert long jumps to short ones if the offset
can be represented in a single byte.

Close #805.

681e81420a vm: make (*Context).IP() return instruction pointer
It is misleading to return +1 in code, and user representation
can always be altered.

3c170271c4 compiler: provide namespace for events names
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.

b5494320f9 compiler, cli: support events from .yml config file
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.

0e2784cd2c always wrap errors when creating new ones with fmt.Errorf()
It doesn't really change anything in most of the cases, but it's a useful
habit anyway.

5ef08f60ae remove github.com/pkg/errors from dependencies
It's not needed any more with Go 1.13 as we have wrapping/unwrapping in base
packages. All errors.Wrap calls are replaced with fmt.Errorf, some strings are
improved along the way.

f2107bfbc4 compiler: copy structs when passing as arguments
In Go structs must be copied when used as arguments.
To do so we must clone struct on VM level.
This is done by appending this struct to an intermediate array.

685d44dbc1 *: support _initialize method in contracts
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.

2. Check arguments count on invocation.
3. Change AppCall to a regular syscall.
