Python 3 requires better UTF-8 handling of files and FreeBSD has UTF-8
characters in some files.
Refactor builder.py to clean up the code and remove the need to have
a temporary file. Update other scripts to use the new code.
Add support to force the RTEMS version. This remove the need for using
the --rtems-version command line option if the automatic detection fails.
Update all python code to support python 2 and 3.
Update rtems_waf to the latest version to support the RTEMS version,
check environment variables and to display the CC version.
Sort all tests. I think the unsorted list is dependent on the version
of python and so would result in repo noise as if it regenerted.
- Update the file builder generator to handle generator specific cflags and
includes. The tcpdump and libpcap have localised headers and need specific
headers paths to see them. There are also module specific flags and these
need to be passed to the lex and yacc generators.
- Add the tcpdump support.
