* server.c (do_cvs_command): add another environment variable,

CVS_SERVER_SLEEP2, after forking to pause the program so one can
attach a debugger.

* sanity.sh (crerepos): clean up crerepos-18 now that multiroot
works in this case.
(multiroot): finalize tests for local vs. remote operation.

* recurse.c (start_recursion): near the beginning, save the list
of directories to spoof as command-line arguments, if necessary.
Use that list near the end and call send_file_names to send those
arguments to the server.
(do_argument_proc): removed, since we call send_file_names now.

* main.c (main): re-initialize dirs_sent_to_server on each pass
through the loop for each CVSROOT.

* cvs.h: add proto for global variable which keeps track of which
directories have been sent to the server when in client mode.

* client.c (is_arg_a_parent_or_listed_dir): new function.
(arg_should_not_be_sent_to_server): new function.  Tries to decide
whether the given argument should be sent to the server, based on
the current CVSROOT and the list of directories sent to the
server.
(send_repository): add the directory name to the list of
directories sent to the server.
(send_file_names): call arg_should_not_be_sent_to_server.

* add.c (add): switch the order of send_files and send_file_names
to make multiple repository support possible.  send_files needs to
create a list of directories being requested so that
send_file_names can decide which command-line arguments to send to
the server for the given current CVSROOT.
