* gpgsm.c (main): Use GNUPG_DEFAULT_HOMEDIR constant.V0-3-9NEWPG-0-3-9
* call-agent.c (start_agent): Create and pass the list of FD to keep in the child to assuan. * call-dirmngr.c (start_dirmngr): Ditto. * scdaemon.c (main): Use GNUPG_DEFAULT_HOMEDIR constant. * assuan-pipe-connect.c (assuan_pipe_connect): No special handling for the log_fd and stderr. Connect stderr to /dev/null if it should not be retained.
