meta-openembedded and poky: subtree updates
Squash of the following due to dependencies among them
and OpenBMC changes:
meta-openembedded: subtree update:d0748372d2..9201611135
meta-openembedded: subtree update:9201611135..17fd382f34
poky: subtree update:9052e5b32a..2e11d97b6c
poky: subtree update:2e11d97b6c..a8544811d7
The change log was too large for the jenkins plugin
to handle therefore it has been removed. Here is
the first and last commit of each subtree:
meta-openembedded:d0748372d2
cppzmq: bump to version 4.6.0
meta-openembedded:17fd382f34
mpv: Remove X11 dependency
poky:9052e5b32a
package_ipk: Remove pointless comment to trigger rebuild
poky:a8544811d7
pbzip2: Fix license warning

However, the MD5 checksum does not add much given its inherent weakness; thus when a checksum fails only the SHA256 sum will now be printed. The md5sum will still be verified if it is specified.

+ <title>npm fetcher changes</title>
+
+ <para>
+ The npm fetcher has been completely reworked in this release. The npm fetcher now only fetches the package source itself and no longer the dependencies; there is now also an npmsw fetcher which explicitly fetches the shrinkwrap file and the dependencies. This removes the slightly awkward <filename>NPM_LOCKDOWN</filename> and <filename>NPM_SHRINKWRAP</filename> variables which pointed to local files; the lockdown file is no longer needed at all. Additionally, the package name in <filename>npm://</filename> entries in <link linkend='var-SRC_URI'><filename>SRC_URI</filename></link> is now specified using a <filename>package</filename> parameter instead of the earlier <filename>name</filename> which overlapped with the generic <filename>name</filename> parameter. All recipes using the npm fetcher will need to be changed as a result.

+ <para>
+ An example of the new scheme:
+ <literallayout class='monospaced'>
+SRC_URI = "npm://registry.npmjs.org;package=array-flatten;version=1.1.1 \
+ npmsw://${THISDIR}/npm-shrinkwrap.json"
+ </literallayout>
+ Another example where the sources are fetched from git rather than an npm repository:
+ <literallayout class='monospaced'>
+SRC_URI = "git://github.com/foo/bar.git;protocol=https \
+ npmsw://${THISDIR}/npm-shrinkwrap.json"
+ </literallayout>
+ </para>
+ <para>
+ devtool and recipetool have also been updated to match with the npm fetcher changes. Other than producing working and more complete recipes for npm sources, there is also a minor change to the command line for devtool: the <filename>--fetch-dev</filename> option has been renamed to <filename>--npm-dev</filename> as it is npm-specific.
