The previous fix#21960 converted the float to an intermediate signed int, before attempting the uint conversion. Although this works, this doesn't guarantee that other architectures will work the same.
This PR reimplements the light client server pool. It is also a first step
to move certain logic into a new lespay package. This package will contain
the implementation of the lespay token sale functions, the token buying and
selling logic and other components related to peer selection/prioritization
and service quality evaluation. Over the long term this package will be
reusable for incentivizing future protocols.
Since the LES peer logic is now based on enode.Iterator, it can now use
DNS-based fallback discovery to find servers.

* accounts/abi: implement new fackball functions
In Solidity v0.6.0, the original fallback is separated
into two different sub types: fallback and receive.
This PR addes the support for parsing new format abi
and the relevant abigen functionalities.
* accounts/abi: fix unit tests
* accounts/abi: minor fixes
* accounts/abi, mobile: support jave binding
* accounts/abi: address marius's comment
* accounts/abi: Work around the uin64 conversion issue

This PR adds service value measurement statistics to the light client. It
also adds a private API that makes these statistics accessible. A follow-up
PR will add the new server pool which uses these statistics to select
servers with good performance.

* les: move execqueue into utilities package
execqueue is a util for executing queued functions
in a serial order which is used by both les server
and les client. Move it to common package.
* les: move randselect to utilities package
weighted_random_selector is a helpful tool for randomly select
items maintained in a set but based on the item weight.
It's used anywhere is LES package, mainly by les client but will
be used in les server with very high chance. So move it into a
common package as the second step for les separation.
* les: rename to utils
