[PATCH 03/10] kconfig: resort the documentation of the environment variables

[Markus Heidelberg]

All the KCONFIG_ environment variables were previously located in a
section "Environment variables in 'menuconfig'", but neither are they
restricted to 'menuconfig' nor are they all used by 'menuconfig'.

Introduce the following three sections for these variables:
  * Environment variables for '*config'
  * Environment variables for '{allyes/allmod/allno/rand}config'
  * Environment variables for 'silentoldconfig'

Furthermore this puts MENUCONFIG_MODE next to MENUCONFIG_COLOR into a
common section "User interface options for 'menuconfig'".

[PATCH 09/10] kconfig: do not hardcode ".config" filename

[Markus Heidelberg]

Rather than hardcoding ".config" use conf_get_configname(), which also
respects the environment variable KCONFIG_CONFIG.

This fixes "make silentoldconfig" when KCONFIG_CONFIG is used and also
suggests the given filename for "Load" and "Save as" in qconf.

[PATCH 10/10] kconfig: do not hardcode "include/config/auto.conf" filename

[Markus Heidelberg]

Regardless of KCONFIG_AUTOCONFIG, the filename written as a Make target
into "include/config/auto.conf.cmd" was always the default one.

Of course this doesn't make it work for the Kernel kbuild system, since
there the filename is hardcoded at several places in the Makefiles.
