This patch cleans up BaseTools.
On classes that are not instantiated and are deisgned as purely base classes,
they get marked using the abstract base class to prevent instantiation.  This
prevents future errors.
Create a new shared base class to centralize some code that was identical in
multiple classes.
cleanup to pass tuples to startswith and endswith instead of calling multiple
times in a single expression.
when an statement used a fixed list or tuple change to a set to allow
hashing to speed up the operation.  if the order was important then make sure
that is a list.  creating on the fly tuples serves no purpose.
use with statements for file opening and make sure we dont over request file
privilidge.  this also seems to have cleaned up the error about the file
AutoGenTimeStamp which was causing errors previously.
lots of work to elimiate concatenating strings as this is a poor performing
operation since strings are immutable and must be completely reallocated and
moved for each concatenation.

Jaben Carsey (11):
  BaseTools: decorate base classes to prevent instantiation
  BaseTools: Workspace - create a base class
  BaseTools: remove unused code
  BaseTools: remove repeated calls to startswith/endswith
  BaseTools: use set presence instead of series of equality
  BaseTools: refactor section generation
  BaseTools: refactor file opening/writing
  BaseTools: refactor to change object types
  BaseTools: refactor to stop re-allocating strings
  BaseTools: change to set for membership testing
  BaseTools: remove extra assignment

use python's ABC (abstract base class) to raise type errors if we instantiate
classes we designed to be used only as base classes for other classes.

delete commented out code
delete never used class/variable/function/import
refactor to remove Ffs class
dont construct class just for class attribute
