* accounts/abi/bind: support for multi-dim arrays
Also:
- reduce usage of regexes a bit.
- fix minor Java syntax problems
Fixes#15648
* accounts/abi/bind: Add some more documentation
* accounts/abi/bind: Improve code readability
* accounts/abi: bugfix for unpacking nested arrays
The code previously assumed the arrays/slices were always 1 level
deep. While the packing supports nested arrays (!!!).
The current code for unpacking doesn't return the "consumed" length, so
this fix had to work around that by calculating it (i.e. packing and
getting resulting length) after the unpacking of the array element.
It's far from ideal, but unpacking behaviour is fixed now.
* accounts/abi: Fix unpacking of nested arrays
Removed the temporary workaround of packing to calculate size, which was
incorrect for slice-like types anyway.
Full size of nested arrays is used now.
* accounts/abi: deeply nested array unpack test
Test unpacking of an array nested more than one level.
* accounts/abi: Add deeply nested array pack test
Same as the deep nested array unpack test, but the other way around.
* accounts/abi/bind: deeply nested arrays bind test
Test the usage of bindings that were generated
for methods with multi-dimensional (and not
just a single extra dimension, like foo[2][3])
array arguments and returns.
edit: trigger rebuild, CI failed to fetch linter module.
* accounts/abi/bind: improve array binding
wrapArray uses a regex now, and arrayBindingJava is improved.
* accounts/abi: Improve naming of element size func
The full step size for unpacking an array
is now retrieved with "getFullElemSize".
* accounts/abi: support nested nested array args
Previously, the code only considered the outer-size of the array,
ignoring the size of the contents. This was fine for most types,
but nested arrays are packed directly into it, and count towards
the total size. This resulted in arguments following a nested
array to replicate some of the binary contents of the array.
The fix: for arrays, calculate their complete contents size:
count the arg.Type.Elem.Size when Elem is an Array, and
repeat when their child is an array too, etc.
The count is the number of 32 byte elements, similar to how it
previously counted, but nested.
* accounts/abi: Test deep nested arr multi-arguments
Arguments with a deeply nested array should not cause the next arguments
to be read from the wrong position.
* accounts/abi: reorganizing package and some notes and a quick correction of name.

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.
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
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`.
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.
