Initial changelog entry created; ChangeLog removed.
ruleset/common/pkgvars.mk:  Set variables, esp. INITRD

Set maintainer and email vars.

Ensure initrd kernel is always built by setting INITRD to YES.  (The
--initrd option to make-kpkg passes INITRD=YES on the make command
line.)
rules:  'make test' prints KPKG_SUBARCH

Used in .config selection
rules:  add useful info to test target
Fix .config target to generate kernel configs with kconfigtool.py

- Add FLAVOR_CONFIG_FILE variable pointing at xenomai config
  - Run 'debian/rules test' to see its value
- Be sure that  .cofig isn't copied from anywhere weird in modules.mk
- Run kconfigtool from common.mk
Delete accidentally committed timestamps, whoops
Add source/format 3.0
.gitignore timestamps
Create stamp/ directory
ruleset/targets/common.mk:  don't remove the /debian directory!
source/format:  backing down to 1.0
pkgvars.mk:  add Xenomai patch
targets.mk:  don't remove stamps directory
changelog:  bump revision
Add XENOMAI_VERSION to KERNELRELEASE
local.mk:  Make .config a prereq of stamp/conf/vars.  Why???

Without something like this, debian/rules build doesn't try to create
the .config at all.
