[Bug-wget] [PATCH v4] Add --use-askpass=COMMAND support

[Liam R. Howlett]

This adds the --use-askpass option which is disabled by default.

--use-askpass=COMMAND will request the username and password for a given
URL by executing the external program COMMAND.  If COMMAND is left
blank, then the external program in the environment variable
WGET_ASKPASS will be used.  If WGET_ASKPASS is not set then the
environment variable SSH_ASKPASS is used.  If there is no value set, an
error is returned.  If an error occurs requesting the username or
password, wget will exit.

Note: I am waiting on a member of our legal team to return from vacation to add
wget to our FSF Contribution Agreement.
