+Subject: fix cloning arrays with unused elements
+
+ce0d59fd changed arrays to use NULL instead of &PL_sv_undef for
+unused elements, unfortunately it missed updating sv_dup_common()'s
+initialization of unused elements, leaving them as &PL_sv_undef.
+
+This resulted in modification of read only value errors at runtime.

+Subject: lib/perl5db.pl: Restore noop lock prototype
+
+cde405a6b9b86bd8110f63531b42d89590a4c56e removed the lock prototype
+"because it's already a do-nothing weak keyword without threads".
+However, that causes "perl -d threaded-script.pl" to complain
+
+ lock can only be used on shared values at /usr/share/perl/5.20/perl5db.pl line 4101.
+ BEGIN failed--compilation aborted at threaded-script.pl line 2.
+ lock can only be used on shared values at /usr/share/perl/5.20/perl5db.pl line 2514.
+ END failed--call queue aborted at threaded-script.pl line 2.
+ Unbalanced scopes: 3 more ENTERs than LEAVEs
+
+because threaded-script.pl's importing of threads::shared enable's
+lock()'s non-noop behavior. Restoring the lock() prototype fixes the
+inconsistency between lock() and share() usage.
