e754ca62db compiler: do not emit CONVERT for syscall results 
When we encounter type assertion CONVERT is emitted.
This isn't needed for SYSCALL (or opcode) results
because value already has needed type.
Problems can arise when result is converted to invalid type
but `neogointernal` package shouldn't be used directly anyway.

b66b853285 compiler: drop stack after inline 
Some control-flow statements drop stack items, for example
`return` when it is used inside of `range` loop.
For inlined calls this `return` should drop only portion of stack
which belongs to inlined call.

d16ef53653 compiler: support ellipsis for append of non-byte slices 
NeoVM lacks opcode for array append, thus some
kind of loop is needed for this.

fc3b840335 compiler: append bytes >0x80 properly 
NeoVM encoding for int(0x80) is []byte{0x80, 0x00} and
byte constant can be used both as integer and as an element
of byte-slice. Thus special case needs to be taken in
`append`.

560aff6155 compiler: adjust init/_deploy method offsets during optimization

cbf26f315c compiler: save both VM and smartcontract types 
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).

a1f98f92fe compiler: add ConvertResultToStruct flag 
Part of #1055.

There'll be a lot of interops which result with a struct on stack instead
of interop interface, and sometimes their names are the same, so it's
unrelyable to take into account interop name only and don't pay
attention to it's API (package).

Also sort syscalls by package and name.
