9a06995460 bigint: don't allocate in ToPreallocatedBytes
Turns out, it's almost always allocating because we're mostly dealing with
small integers while the buffer size is calculated in 8-byte chunks here, so
preallocated buffer is always insufficient.

name                   old time/op    new time/op    delta
ToPreallocatedBytes-8    28.5ns ± 7%    19.7ns ± 5%   -30.72%  (p=0.000 n=10+10)

name                   old alloc/op   new alloc/op   delta
ToPreallocatedBytes-8     16.0B ± 0%      0.0B       -100.00%  (p=0.000 n=10+10)

name                   old allocs/op  new allocs/op  delta
ToPreallocatedBytes-8      1.00 ± 0%      0.00       -100.00%  (p=0.000 n=10+10)

Fix StorageItem reuse at the same time. We don't copy when getting values from
the storage, but we don when we're putting them, so buffer reuse could corrupt
old values.

10110d4e70 bigint: correct MaxBytesLen
It can't be 33, positive signed int256 all fit into 32 bytes (no need for
leading zero), negative ones fit into 32 bytes as well.

3945e81857 bigint: don't allocate in ToPreallocatedBytes() for negative numbers
In-place modifications are somewhat dangerous, but yet another allocation is
quite costly.

5a3fa47b95 encoding: panic on nil slice
After `state.StorageItem` became a slice of bytes
we no longer panic on accessing `si.Value`. This helps
to ensure that nothing was broken. Providing `nil` to `FromBytes`
is probably an error anyway.

Quoted or not, they should be unmarshalled without going through float64.

ff11a5f990 state: use more efficient encoding for amount
It's variable-length anyway, so wasting 8 bytes for what typically is 1 byte
makes no sense.

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.

7b4ca57e33 *: change address to the new format
NEO3 uses new prefix for address (53 = 0x35), thus string representations as
well as encrypted WIFs should be changed.

It doesn't belong to crypto in any way other than it uses hash function
