zed supports a '-M' cmdline opt to lock all pages in memory via mlockall(). The _POSIX_MEMLOCK define is checked to determine whether this function is supported. The current test assumes mlockall() is supported if _POSIX_MEMLOCK is non-zero. However, this test is insufficient according to mlock(2) and sysconf(3). If _POSIX_MEMLOCK is -1, mlockall() is not supported; but if _POSIX_MEMLOCK is 0, availability must be checked at runtime. This commit adds an autoconf check for mlockall() to user.m4. The zed code block for mlockall() is now guarded with a test for HAVE_MLOCKALL. If defined, mlockall() will be called and its runtime availability checked via its return value.
