bitbake: move configuration reading code

The configuration reading code should live in the
main bitbake entry point, and the server modules should
be supplied with correct configuration instead of attempting
to parse from configuration files.

This patch moves the endpoint address reading from XMLRPC
to the bitbake main script.

xmlrpc: client - remove fatal errors

When we use the XMLRPC client API to connect to a bitbake server,
we want to receive errors from the API instead of having the
API exiting without warning.

Thus the "bb.fatal" calls have been replaced with "bb.warn" calls,
and we re-raise the original exception for handling by the
original caller.

The bitbake starting script has been modified to properly test
for failures in calling the client API and handle them.

Additional error handling added in the client, as to prevent
fatal crashes.

uievent: retry on handler registration failure

The registration of a remote UI event handler may fail
if the server cooker is currently in some certain states.
This may happen, for example, when a remote UI is started
very fast after the bitbake server is started, and the
server hadn't time to finish initial configuration parsing.

Rather than fail outright, we have the remote UI event retry
registration for five time at one-second intervals,
in the hope it will succeed.

toaster: read database settings from the environment

We add the capability to read the database settings for
Toaster from the environment. The DATABASE_URL is intepreted
and used to override the default settings.

This capability is essential for easy deployment of Toaster
in a managed hosted environment, and for creating
build environments with custom database settings.

toaster: startup script noweb mode

We add an option to the startup script, named "noweb" that
will start toaster without the embedded web server.

This is useful to start the system for build-only environments,
where the web server code is running on a different machine.

toaster: startup script standalone mode

The toaster starter script was designed to be sourced in
a build environment and set up the build recording environment
to be used in an interactive mode.

For the standalone web server mode, we modify the toaster
script to be run directly from the checked-out sources,
without a build environment set up, and run the web server
alone. In the standalone mode, the build environemnts and
all build activities are controled through the web interface.

toaster: update toaster to run in managed mode

We disable bitbake self start to prevent race condition.

ToasterUI will shutdown the server when the build is done
if running in managed mode.

We fix usage of kill server flag in the bitbake binary.

toaster: add project related models

We introduce the notion of a project in Toaster as the item
that holds the specification for triggering a build: the set
of layers used, the set of configuration variable values, and
the set of targets to be build.

Builds triggered through Toaster will be associated with a
Project, and they will be configured based on the project
settings at the moment when the build is ordered.

toasterui: fix django settings environment value

Previously, the buildinfohelper only set a django settings module
environment variable if none were set.

This may lead to problems when the starting the toasterui
from an already existing Django environment.

As such, we always override the variable to provide the
correct name for the local Django settings module.

bitbake: show wildcard appends for bitbake-layers
