[OE-core] [PATCH 0/3] Support additional user-defined package metadata

[Leonid Borisenko]

I'm an owner of Kindle Touch. It's basically a computer with ARM
Cortex-A8 based CPU and Linux. There is a [small] community of
enthuasists developing homebrew modifications for stock software. For
distributing of these modifications .ipk package format had been chosen
with OE as build infrastructure.

There are already several firmware versions for device and some more are
expected. Every firmware can introduce unpredictable changes, so
modifications for previous firmware versions could stop working.

Custom metadata field with supported firmware version(s) could be
included into package control file for preventing of installing packaged
modifications onto unsupported firmware.

But OE currently doesn't allow to define additional package metadata in
recipes. Patch fixes it.

There is already RPMSPEC_PREAMBLE variable used in package_rpm.bbclass.
I think, it is still useful for defining custom macros in header of spec
file (while additional user-defined metadata is placed somewhere between
common tags).

I didn't found any way to define newline character inside variable value
and it is needed to allow multiple [one-line] metadata fields/tags. So
I've used ability of OE to split list-typed variables (and re-joined
splitted value with real newline character).

The following changes since commit cab85fd0b481cdbf36477348de75352be3f38ca2:
