Tidy up CPDFDOC_Environment.

- untabify as encountered.
- Only put single-statement method in .h file, move more
  complex methods to .cpp (counting an if without braces as
  a single statement, killing braces as needed).
- Move invariant arguments to constructor and make
  corresponding members const.
- Make all members private and add accessor methods.
- Make existing accessor methods const where possible.
- Kill meaningless asserts.
- Add helper functions in place of duplicate code.
- Rename GetCurrentDoc() to GetSDKDocument(), since the class
  has two document members, one of CPDF_Document and one of
  CPDFSDK_Document, making it clear which one you get.
- Simplify some logic with early returns.
