    Mono.Unix/UnixProcess.cs, Mono.Unix/UnixSymbolicLinkInfo.cs,
    Mono.Unix/UnixUser.cs, Mono.Unix/UnixUserInfo.cs: Change types of
    [Obsolete] members for consistency and CLS compliance;
    Mono.Unix.Native type migration.
  * Mono.Unix/FileTypes.cs: s/Special/Device/g
    (CharacterSpecial ==> CharacterDevice).  The *Special was a BSD
    convention, while UnixFileSystemInfo uses *Device in property names, and
    these should be consistent.  Changing the enum is simpler than changing
    the UnixFileSystemInfo properties.
  * Mono.Unix/UnixIOException.cs: s/error/errno/g (FxCop suggestion); change
    type of ErrorCode property.
  * Mono.Unix/UnixMarshal.cs: s/error/errno/g (FxCop suggestion);
    Mono.Unix.Native type migration.

  * Test/Mono.Unix/UnixGroupTest.cs: The type of UnixGroupInfo.GroupId changed.
    UnixGroup is deprecated; use UnixGroupInfo instead.
  * Test/Mono.Unix/UnixUserTest.cs: The type of UnixUserInfo.UserId changed.
    UnixUser if deprecated; use UnixUserInfo instead.
