re: github issue #1425
The 'ncdump -v' command causes a constraint to be sent
to the opendap code (in libdap2). This is a separate path
from specifying the constraint via a URL.
This separate path encoded its constraint using code independent
of and duplicative of that provided by ncuri.c and this duplicate
code did not properly encode the constraint, which might include
square brackets.
Solution chosen here was to get rid of the duplicate code and
ensure that all URL escaping is performed in the ncuribuild function
in the ncuri.c file.
Also removed the use of the NEWESCAPE conditional in ncuri.c
because it is no longer needed.
