[patch] Refactor wordexp-test

Authentication-results: sourceware.org; auth=none

Greetings,

This patch modifies wordexp-test.c such that words always ends at the
edge of unreadable page.

This makes it easy to catch overflows, such as BZ #18043 (and BZ #18042).

Tested: reverted fix for BZ #18043 in wordexp.c and verified that the
test for it fails with expected SIGSEGV.


Thanks,

2015-03-06  Paul Pluzhnikov  <ppluzhnikov@google.com>

        * posix/wordexp-test.c (test_case): Add test for BZ #18043
        (do_bz18043): Delete.
        (at_page_end): New.
        (testit): Refactor to have words at the edge of unreadable page.
