bitbake: bitbake-setup: further rework the settings handling

Browse Source 
After some further feedback, additional changes are made:

1. 'setting' command is renamed to 'settings' to better reflect
that it is an interface to various ways of managing settings.

2. This command now has a -l/--list option to list all settings
with their values (same as 'git config -l').

3. A new level of settings (built-in defaults) is added,
and used as a last resort after command line options, top dir
settings file and global settings file.

4. This means bitbake-setup does not have to write and use a
global settings file, and it no longer does so when initializing
a build, avoiding default 'pollution' of ~/.config/bitbake-setup/
which can be problematic or unwelcome.

A global settings file is still created if a setting is explicitly
requested to be placed into it.

5. 'install-global-settins' is removed as the use case for it
(tweak default settings before using them to initialize a build)
can be achieved by setting the settings individually.

5. Similarly, a top dir settings file is no longer created by default
and only appears if a setting needs to be written into it.

6. Default dl-dir is again created inside a top directory and not
in ~/.cache/ to make default builds fully contained in the top
directory (which was also asked about).

(Bitbake rev: 664f8ec48d42d2ddc5f234c4f7d590fa597f489a)
