to get TOPSRCDIR that avoids use of TEST_ENVIRONMENT and makes automake and cmake more consistent. Basic assumption is that abs_top_srcdir (and cmake equivalent) is known at 'make check' time, so we can use -D flag to compile a program that has the value of abs_top_srcdir embedded into it as a constant. We define two new files in ncdap_test: 1. t_srcdir.h -- provide a gettopsrcdir() function to return the topsrcdir value to the test program. 2. topsrcdir.c -- a program that calls gettopsrcdir() and prints its output (minus any newline) on stdout. This is used in .sh files to get topsrcdir.
