directory. OpenVMS couldn't open a file through symbolic link. This macro is mainly used
in test/links.c for the function call external_symlink and in src/H5F.c.
Tested the same change for 1.8 on OpenVMS.

Add detection for POSIX lstat() routine to configure script (mostly for
non-UNIX/Linux machines) and add macro wrapper for it.
Alphabetatize the system/library calls we test for, to make them easier
to read.
Removed the sigaction() detection & macro wrappers, since it's not
used by the distribution currently.
