new -w option for bsqldb(1)

I will write the description such that it could be copied right into the man pages, serving multiple purposes

Options

-w n This option instructs bsqldb(1) to pause or wait
for n seconds between each request (or GO). This
option allows developers to send a batch of
requests to a server but pause for each request,
perhaps to monitor the wire protocol or examine
ends of the communication.

Possible values are:
If n is zero, then bsqldb(1) will pause forever
prompting the user and requiring user action.
if n is non-zero positive number, then each
request is paused or throttled for n seconds.
if n is non-zero negative number, (the default),
no pausing takes place and bsqldb(1) operates at
full speed (subject to road and env conditions).

Also, this is my first time doing this, so if you see some issues, let me know...

I started my code change based on freetds-0.64.tgz. I have only modified src/apps/bsqldb.c. Today I downloaded the HEAD version of this file (Rev 1.3) from the CVS and generated a diff against the two files (enclosed here).
