devtool: add search command
Adds a subcommand to search to find the target recipe name providing some file or capability. This is implemented by searching on recipe name, package name, description, package contents (file names), and runtime file provides. For example: $ devtool search libGL mesa $ devtool search X11 xextproto libxxf86vm xf86driproto xf86vidmodeproto libxfixes xproto libx11 ... $ devtool search /bin/sed busybox sed This is particularly useful within the extensible SDK but is also made available in devtool alongside the build system. Note of course that because this searches pkgdata, useful results depend upon do_packagedata(_setscene) having executed for the recipe being searched for. (From OE-Core rev: 48cbde0ea77ed20126eceba5feb37c42a9229500) Signed-off-by: Paul Eggleton <paul.eggleton@linux.intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
