Merge r1541655 and 1541666 from trunk:

Fix message when !APR_HAS_MMAP

Read the contents of the test datafile instead of
hard-coding it in the source and relying on the line
ending in the datafile to be the same as APR_EOL_STR.
(Or, allow building and testing on Windows and Unix
using the same release tarball.)
