internal/{socks,sockstest}: new packages

This change factors out the code related to SOCKS protocol version 5
from the golang/x/net/proxy package and provides new SOCKS-specific
API to fix the following:
- inflexbility of forward proxy connection setup; e.g., no support for
  context-based deadline or canceling, no support for dial deadline,
  no support for working with external authentication mechanisms,
- useless error values for troubleshooting.

The new package socks is supposed to be used by the net/http package
of standard library and proxy package of golang.org/x/net repository.

Fixes golang/go#11682.
Updates golang/go#17759.
Updates golang/go#19354.
Updates golang/go#19688.
Fixes golang/go#21333.
