91a7a4a786 accounts/abi: fixed unpacking in to already slice interfaces
Previously it was assumed that wheneven type `[]interface{}` was given
that the interface was empty. The abigen rightfully assumed that
interface slices which already have pre-allocated variable sets to be
assigned.

This PR fixes that by checking that the given `[]interface{}` is larger
than zero and assigns each value using the generic `set` function (this
function has also been moved to abi/reflect.go) and checks whether the
assignment was possible.

The generic assignment function `set` now also deals with pointers
(useful for interface slice mentioned above) by dereferencing the
pointer until it finds a setable type.

5127ec10cb accouns/abi: refactored ABI package
Refactored the abi package parsing and type handling. Relying mostly on
package reflect as opposed to most of our own type reflection. Our own
type reflection is still used however for cases such as Bytes and
FixedBytes (abi: bytes•).

This also inclused several fixes for slice handling of arbitrary and
fixed size for all supported types.

This also further removes implicit type casting such as assigning,
for example `[2]T{} = []T{1}` will fail, however `[2]T{} == []T{1, 2}`
(notice assigning *slice* to fixed size *array*). Assigning arrays to
slices will always succeed if they are of the same element type.

Incidentally also fixes #2379

fe45210c55 accounts/abi: Fixed bytes input accept []byte and variable input support
Fixed up `[]byte` slice support such that `function print(bytes input)`
accepts `[]byte` as input and treats it as 1 element rather than a slice
of multiple elements.

Added support for variable length input parameters like `bytes` and
`strings`.

6fe917ecb8 accounts/abi: support for typed array
Added support for fixed size and arbitrary length byte arrays to be
marshallable in fixed size (typed) byte slices.

ecc876cec0 accounts/abi: fixed return tuple and string, bytes return type parsing
Removed old unmarshalling of return types: `abi.Call(...).([]byte)`.
This is now replaced by a new syntax:

```
var a []byte
err := abi.Call(&a, ...)
```

It also addresses a few issues with Bytes and Strings and can also
handle both fixed and arbitrary sized byte slices, including strings.

bddf8f76c8 account/abi: implements event parsing
Implementation of basic event parsing and its input types. This
separates methods and events and fixes an issue with go type parsing and
validation.

All code outside of cmd/ is licensed as LGPL. The headers
now reflect this by calling the whole work "the go-ethereum library".
