[OpenJDK 2D-Dev] RFR: JDK-8035821: Move psfont properties files from src/share/classes to src/share/lib

Hi Phil,

Is psfont*.properties* file more of a resource file?  Is there any 
reason (or specification) that psfont*.properties has to be in JRE/lib 
directory? One potential reason might be the startup performance (warm 
start/cold start) to avoid opening a jar file? They don't look like a 
user-editable properties file and that could be the reason why they live 
in src/share/classes.

As part of the modularization effort, we want to separate the 
user-editable configuration file from the non-modifiable resource 
files.   For the non-modifiable resource files, does it make sense to 
move them together with the classes like other java resources?

What Erik is doing to prepare for the source restructuring to enable the 
module build such that we can build one module at a time (i.e. you can 
just build the desktop module + its dependencies and skip the rest of 
JDK build).

Here are the list of files under JRE/lib directory.  Do you see any 
reason any of these can be moved to a different directory e.g. together 
with the classses?
