Lubomir I. Ivanov (VMware) 7a218942be os/user: obtain a user home path on Windows
newUserFromSid() is extended so that the retriaval of the user home
path based on a user SID becomes possible.

(1) The primary method it uses is to lookup the Windows registry for
the following key:
  HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList\[SID]

If the key does not exist the user might not have logged in yet.
If (1) fails it falls back to (2)

(2) The second method the function uses is to look at the default home
path for users (e.g. WINAPI's GetProfilesDirectory()) and append
the username to that. The procedure is in the lines of:
  c:\Users + \ + <username>

The function newUser() now requires the following arguments:
  uid, gid, dir, username, domain
This is done to avoid multiple calls to usid.String() and
usid.LookupAccount("") in the case of a newUserFromSid()
call stack.

The functions current() and newUserFromSid() both call newUser()
supplying the arguments in question. The helpers
lookupUsernameAndDomain() and findHomeDirInRegistry() are
added.

This commit also updates:
- go/build/deps_test.go, so that the test now includes the
"internal/syscall/windows/registry" import.
- os/user/user_test.go, so that User.HomeDir is tested on Windows.
