Environment variable 'ALL_PROXY=socks5h://example.com' is commonly
used to specify a SOCKS5 proxy server.
In curl, 'socks5' means the host name will be resolved locally,
and 'socks5h' means the host name will be resolved by the server.
Go SOCKS5 client always uses the server to resolve host names.
So this change just added socks5h as a supported URL scheme.

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.

Split off a new SOCKS5 connect() method from Dial.
connect() takes an existing connection to a socks5 server, and
commands the server to extend that connection to a given target
address and port.

SOCKS5 uses a single-byte field for domain name length. This change
causes dials to domain names longer than 255 chars to fail instead
of sending an invalid request to the proxy.

The code was using the SOCKS version number (5) where it should have been using the username/password protocol version number (1).
With this change, username/password authentication actually works.

address are not allowed to be used in wire protocols.

net.IP represents either an IPv4 or IPv6 address. In case of
the address of IPv4 node, it uses IPv4-mapped IPv6 address
format by default.

This change copies exp/proxy to go.net without any code changes. A
followup CL will remove exp/proxy.
