Message:

Test suite: Allow the user to disable use of "flock"

Using "flock" causes trouble on some exotic architectures (e.g. Hurd),
so allow disabling it. Running without lock files requires serial
execution of test cases to achieve reliable results.

Files:

• configure.ac (modified) (1 diff)
• test/Makefile.am (modified) (3 diffs)
• test/common.bash (added)
• test/proxy_backend.bash (modified) (4 diffs)
• test/runtests (modified) (3 diffs)
