In some cases the license-identification header was missing,
so I added that as well. Replaced the remaining headers that
specifically identified "Versions 3.13.7 and higher".
Makefiles and the build system were deliberately excluded.
This fixes the perl compilation failures of fullPathName.pl
that occur before the src/tools directory has been built, and
ensures that the other tools that use EPICS modules also work.
Removed the -h option to convertRelease, use $ENV{EPICS_HOST_ARCH} instead.
Reworked variables associated with expandVars to make it simpler to use.
Split EPICS::Utils module into three parts.
Moved code from fullPathName.pl into the new EPICS::Path module.
Changed convertRelease.pl to use new modules.
Added some documentation to RELEASE_NOTES.html
