commit 75daad8401f036d2117d6ad3e558b52ae50fc243
Author: Josh Stone <jistone@redhat.com>

    remote: Normalize the shell used to invoke stapsh
    
    We're using a little bit of shell magic on the remote side to tell
    whether a system has stapsh available, but that magic depends on
    specific shell functionality.  We now explicitly start it with
    /bin/bash, so the user's choice of $SHELL doesn't matter.
    
    * remote.cxx (ssh_remote::connect): Wrap the command in /bin/bash -c.

    Loop server requests over every remotes' session
    
    Now the list/trust-server options work on every unique session generated
    by the requested remote targets.  This enables usage such as:
        $ stap --remote HOST --list-servers
    
    * main.cxx (passes_0_4): Move the version/session banner to main.
      (main): Print the version just once, and the session banner for each
      unique session.  Perform server actions within the session loop.

    Restore signals after removing the tmpdir
    
    This is necessary because passes_0_4_again_with_server() will remove the
    tmpdir before trying again on a server.  If it is then successful, the
    proceeding run should be interruptible as normal.
    
    * main.cxx (remove_temp_dir): Restore signals after removal.
