Remove unneeded whitespace.

* fhandler_fifo.cc (fhandler_fifo::open): Rework to cause errno to be set to
ENXIO when opening a fifo write/nonblocking.
* environ.cc (ucreqenv): Rename to ucenv.  Move code from old ucenv here and
conditionalize it on create_upcaseenv.
(ucenv): Delete.
(environ_init): Fix compiler warning by moving create_upcaseenv test to ucenv.
Don't bother checking for child_proc_info when calling ucenv since it is
assumed to be NULL at the point where the function is called.
* path.cc (symlink_worker): Turn off MS-DOS path warnings when dealing with
devices since the device handler passes in a translated MS-DOS path.
* sec_auth.cc (lsaprivkeyauth): Avoid variable initialization which causes a
compiler error.
* fhandler_netdrive.cc: Update copyright.
