opkg: Backport improvements to opkg-key

The improvements to opkg-key made for v0.3.0 are backported. The rest of v0.3.0
needs further testing and bugfixing prior to release, but the improvements to
opkg-key have been tested and work well.

+Subject: [PATCH] opkg-key: Backport improvements
+
+The improvements to opkg-key made for v0.3.0 are backported. The rest of v0.3.0
+needs further testing and bugfixing prior to release, but the improvements to
+opkg-key have been tested and work well.
+
+    1) opkg-key: Add 'reset' option
+
+        This option removes the keyrings used to verify package signatures,
+        effectively resetting opkg to the initial state where it recognises no
+        keys.
+
+    2) opkg-key: Add 'populate' option
+
+        This option causes all keyrings in /usr/share/opkg/keyrings to be
+        imported. Thus distributions may install their keys into this directory
+        and use 'opkg-key populate' to ensure the correct keys are loaded.
+
+    3) opkg-key: Improve usage output
