Title:
  SRU: apply four upstream bug fixes in bash for 16.04 LTS

Status in bash package in Ubuntu:
  New

Bug description:
  Proposing to apply the four upstream changes to the bash package for
  xenial, plus the addition to the PATH variable.

    * Apply upstream patches 043 - 046. Fixes:
      - When the lastpipe option is enabled, the last component can contain
        nested pipelines and cause a segmentation fault under
        certain circumstances.
      - A typo prevents the `compat42' shopt option from working as intended.
      - If a file open attempted as part of a redirection fails because it is
        interrupted by a signal, the shell needs to process any pending traps
        to allow the redirection to be canceled.
      - An incorrect conversion from an indexed to associative array can result
        in a core dump.
    * Add $HOME/.local/bin to PATH, and add the user's home directories
      unconditionally to the path, so that they are available without
      a new login. Closes: #820856, LP: #1588562.

  The rationale for the PATH change is explained in LP: #1588562.

  Verification: The package builds, passes it's tests, and for new users
  you'll find $HOME/.local/bin in PATH.
