Now that we are using absolute paths we can remove some of the sys.path
mangling that appears in the tools.

We only need to add the path to 'tools/' so that everything can find
modules relative to that directory.

The special paths for finding pylibfdt remain.

At present patman sets the python path on startup so that it can access
the libraries it needs. If we convert to use absolute imports this is not
necessary.

Move patman to use absolute imports. This requires changes in tools which
use the patman libraries (which is most of them).

At present buildman sets the python path on startup so that it can access
the libraries it needs. If we convert to use absolute imports this is not
necessary.

Move buildman to use absolute imports. Also adjust moveconfig.py too since
it uses some buildman modules and cannot work without this.

The naming is slightly different on kernel.org now. Update the regex so
that the test still passes.

These are becoming more common now. They cause boards to show warnings
which can be mistaking for compiler warnings.

Add a buildman option to ignore them. This option works only with the
summary option (-s). It does not affect the build process.

Unfortunately the plague of device-tree warnings has not lifted. These
warnings infiltrate almost every build, adding noise and confusion.

Add a buildman option to ignore them. This option works only with the
summary option (-s). It does not affect the build process.

When buildman finishes it leaves the last summary line visible, which
shows the number of successful builds, builds with warnings and builds
with errors.

It is useful also to see how many builds were done in total along with
the time taken. Show these on a separate line before buildman finishes.

At present the board names shown with -l are separated by commas. This
makes it hard to double-click to select a particular board. Also it is not
possible to select all boards and paste them as arguments to a subsequent
buildman run, since buildman requires spaces to separate the list on the
command line, not commas.

Change the output format to use spaces instead of commas.

It is quite hard to see the list of board for each error line since the
colour is the same as the actual error line. Show the board list in
magenta so that it is easier to distinguish them.

There is no point in checking the colour of the overall line, since there
are now multiple colours. So drop those tests.

At present warnings are shown in yellow in the summary (-s) but magenta in
the detail listing (-e). Use yellow in both.
