  hash: move SHA1 implementations into 'sha1/' folder
  
  As we will include additional hash algorithms in the future due
  to upstream git discussing a move away from SHA1, we should
  accomodate for that and prepare for the move. As a first step,
  move all SHA1 implementations into a common subdirectory.
  
  Also, create a SHA1-specific header file that lives inside the
  hash folder. This header will contain the SHA1-specific header
  includes, function declarations and the SHA1 context structure.
