[PATCH] debianize: introduce DEBIAN_PROVIDES and DEBIAN_REPLACES

[srinuvasan.a]

From: Srinuvasan A <srinuvasan.a@siemens.com>

Allow setting the Provides and Replaces field for auto generated control files,
with this changes now user can configure the provides and replaces in the debian/control file.

Recipes can simply setting the Provides and Replaces field now by defining the
DEBIAN_PROVIDES and DEBIAN_REPLACES variable.

Hello Srinuvasan,

We are going to perform a new release today. All the targets were
already tested and adding any new patches on top will results in
postponing the release.
As your patch is not a fix but improvement we plan to apply it right
after the tagging.

This looks like considering my comment in the same patch from Cedric
Hombourger
(https://groups.google.com/g/isar-users/c/fpPkw0WxQno/m/CLIq3fo8BwAJ),
but this patch misses original modification of user_manual.md.

Something is wrong with your mail setup. The From: header 
is "Srinuvasan Arjunan <srinuvasan_a@mentor.com>" while your singed-
off-by and the From: part of the body is set to "Srinuvasan
<srinuvasan.a@siemens.com>"

Would not this somehow lead to broken control file if these new
variables are not defined / not used in the recipe? For other vars here
(e.g., DEBIAN_CONFLICTS, DEBIAN_DEPENDS) we at least have a weak
assignments (??= "") on top of debianize.bbclass.

[PATCH] debianize: introduce DEBIAN_PROVIDES and DEBIAN_REPLACES

[Cedric Hombourger]

When optimizing an embedded system (and mostly for advanced users),
dpkg-raw may be used to generate virtual packages to replace larger
packages that would otherwise be pulled to satisfy image dependencies.
