Refresh toolbox.

Use more upstream NetBSD, and update those things that were already NetBSD.

Note that unlike bionic, the upstream-netbsd directory isn't pristine; we have
changes marked by __ANDROID__.

Bug: 16493461

(cherry picked from commit fd4c6b0a3a25921a9fe24691a695d715aecb6afe)

+ * rm_overwrite --

+ * regular files are deleted, directories (and therefore names) will remain.
+ * Also, this assumes a fixed-block file system (like FFS, or a V7 or a
+ * System V file system).  In a logging file system, you'll have to have
+ * kernel support.
+ *
+ * A note on standards:  U.S. DoD 5220.22-M "National Industrial Security
+ * Program Operating Manual" ("NISPOM") is often cited as a reference
+ * for clearing and sanitizing magnetic media.  In fact, a matrix of
+ * "clearing" and "sanitization" methods for various media was given in
+ * Chapter 8 of the original 1995 version of NISPOM.  However, that
+ * matrix was *removed from the document* when Chapter 8 was rewritten
+ * in Change 2 to the document in 2001.  Recently, the Defense Security
+ * Service has made a revised clearing and sanitization matrix available
+ * in Microsoft Word format on the DSS web site.  The standardization
+ * status of this matrix is unclear.  Furthermore, one must be very
+ * careful when referring to this matrix: it is intended for the "clearing"
+ * prior to reuse or "sanitization" prior to disposal of *entire media*,
+ * not individual files and the only non-physically-destructive method of
+ * "sanitization" that is permitted for magnetic disks of any kind is
+ * specifically noted to be prohibited for media that have contained
+ * Top Secret data.
+ *
+ * It is impossible to actually conform to the exact procedure given in
+ * the matrix if one is overwriting a file, not an entire disk, because
+ * the procedure requires examination and comparison of the disk's defect
+ * lists.  Any program that claims to securely erase *files* while 
+ * conforming to the standard, then, is not correct.  We do as much of
+ * what the standard requires as can actually be done when erasing a
+ * file, rather than an entire disk; but that does not make us conformant.
+ *
+ * Furthermore, the presence of track caches, disk and controller write
+ * caches, and so forth make it extremely difficult to ensure that data
+ * have actually been written to the disk, particularly when one tries
+ * to repeatedly overwrite the same sectors in quick succession.  We call
+ * fsync(), but controllers with nonvolatile cache, as well as IDE disks
+ * that just plain lie about the stable storage of data, will defeat this.
+ *
+ * Finally, widely respected research suggests that the given procedure
+ * is nowhere near sufficient to prevent the recovery of data using special
+ * forensic equipment and techniques that are well-known.  This is 
+ * presumably one reason that the matrix requires physical media destruction,
+ * rather than any technique of the sort attempted here, for secret data.
+ *
+ * Caveat Emptor.
+ *
+ * rm_overwrite will return 0 on success.
