prevent memory leak when going out of memory

allow out-of-memory testing by setting a limit. That number of memory
allocation calls will succeed, the following will return NULL!

better freeing when bailing out due to bad output glob

free data on failure

test87 verifies the new and better check for bad -o #[num] stuff

ignore the .pid files

ignore lib506 too

better report on why tests are skipped, and also show a count of the amount
of test cases that were "considered".

In case the output urlglob file name returned is NULL, then there was
badness in the string and we help our user by returning an error.

modified the #[num] code to be more robust, to return NULL on errors and
to support numbers larger than 9

corrected this test case

test urlglobbing range requests

test86 added

David Byron's fix that makes this script use 'cygpath' instead of 'pwd' if
this runs on windows, to find out the current working directory.
