Subject: [PATCH] Add UUID support to Asterisk.

This provides a common API for dealing with unique identifiers.
The API provides methods to create, parse, copy, and stringify UUIDs.

An accompanying unit test is provided that tests all operations.

(closes issue ASTERISK-20726)

+   Here is a matrix of mmap possibilities:
+	mmap private not fixed
+	mmap private fixed at somewhere currently unmapped
+	mmap private fixed at somewhere already mapped
+	mmap shared not fixed
+	mmap shared fixed at somewhere currently unmapped
+	mmap shared fixed at somewhere already mapped
+   For private mappings, we should verify that changes cannot be read()
+   back from the file, nor mmap's back from the file at a different
+   address.  (There have been systems where private was not correctly
+   implemented like the infamous i386 svr4.0, and systems where the
+   VM page cache was not coherent with the file system buffer cache
+   like early versions of FreeBSD and possibly contemporary NetBSD.)
+   For shared mappings, we should conversely verify that changes get
+   propagated back to all the places they're supposed to be.
+
+   Grep wants private fixed already mapped.
+   The main things grep needs to know about mmap are:
+   * does it exist and is it safe to write into the mmap'd area
+   * how to use it (BSD variants)  */

-   Here is a matrix of mmap possibilities:
-	mmap private not fixed
-	mmap private fixed at somewhere currently unmapped
-	mmap private fixed at somewhere already mapped
-	mmap shared not fixed
-	mmap shared fixed at somewhere currently unmapped
-	mmap shared fixed at somewhere already mapped
-   For private mappings, we should verify that changes cannot be read()
-   back from the file, nor mmap's back from the file at a different
-   address.  (There have been systems where private was not correctly
-   implemented like the infamous i386 svr4.0, and systems where the
-   VM page cache was not coherent with the file system buffer cache
-   like early versions of FreeBSD and possibly contemporary NetBSD.)
-   For shared mappings, we should conversely verify that changes get
-   propagated back to all the places they're supposed to be.
-
-   Grep wants private fixed already mapped.
-   The main things grep needs to know about mmap are:

+	 * uuid_generate(), uuid_generate_random(), and uuid_generate_time().
+	 *
+	 * uuid_generate_random() creates a UUID based on random numbers. The method
+	 * attempts to use either /dev/urandom or /dev/random to generate random values.
+	 * If these resources are unavailable, then random numbers will be generated
+	 * using C library calls to generate pseudorandom numbers.
+	 * This method of generating UUIDs corresponds to section 4.4 of RFC 4122.
+	 *
+	 * uuid_generate_time() creates a UUID based on the current time plus
+	 * a system identifier (MAC address of the ethernet interface). This
+	 * method of generating UUIDs corresponds to section 4.2 of RFC 4122.
+	 *
+	 * uuid_generate() will check if /dev/urandom or /dev/random is available to
+	 * use. If so, it will use uuid_generate_random(). Otherwise, it will use
+	 * uuid_generate_time(). The idea is that it avoids using pseudorandom
+	 * numbers if necessary.
+	 *
+	 * For our purposes, we do not use the time-based UUID at all. There are
+	 * several reasons for this:
+	 *
+	 * 1) The time-based algorithm makes use of a daemon process (uuidd) in order
+	 * to ensure that any concurrent requests for UUIDs result in unique results.
+	 * Use of this daemon is a bit dodgy for a few reasons
+	 *
+	 *     a) libuuid assumes a hardcoded location for the .pid file of the daemon.
+	 *     However, the daemon could already be running on the system in a different
+	 *     location than expected. If this is the case, then attempting to connect
+	 *     to the daemon will fail, and attempting to launch another instance in
+	 *     the expected location will also fail.
+	 *
+	 *     b) If the daemon is not running, then the first attempt to create a
+	 *     time-based UUID will result in launching the daemon. Because of the hard-
+	 *     coded locations that libuuid assumes for the daemon, Asterisk must be
+	 *     run with permissions that will allow for the daemon to be launched in
+	 *     the expected directories.
+	 *
+	 *     c) Once the daemon is running, concurrent requests for UUIDs are thread-safe.
+	 *     However, the actual launching of the daemon is not thread-safe since libuuid
+	 *     uses no synchronization primitives to ensure that only one thread (or process)
+	 *     launches the daemon.
+	 *
+	 *     d) When libuuid launches the daemon, it sets an inactivity timer.
+	 *     If no UUID generation requests are issued in that time period,
+	 *     then the daemon will exit. If a new request should occur after the daemon
+	 *     exits, then the daemon will be relaunched. Given point c), we cannot
+	 *     necessarily guarantee the thread-safety of time-based UUID generation since
+	 *     we cannot necessarily guarantee the daemon is running as we expect.
+	 *     We could set up a watchdog thread to generate UUIDs at regular intervals to
+	 *     prevent the daemon from exiting, but frankly, that sucks.
+	 *
+	 * 2) Since the MAC address of the Ethernet interface is part of the UUID when
+	 * using the time-based method, there is information leaked.
+	 *
+	 * Given these drawbacks, we stick to only using random UUIDs. The chance of /dev/random
+	 * or /dev/urandom not existing on systems in this age is next to none.
+	 */
+
+	/* XXX Currently, we only protect this call if the user has no /dev/urandon on their system.
+	 * If it turns out that there are issues with UUID generation despite the presence of
+	 * /dev/urandom, then we may need to make the locking/unlocking unconditional.
