Patch: Regenerate JNI headers automatically

[Thomas Fitzsimmons]

Hello,

This patch adds a configure flag that enables automatic regeneration of
JNI headers.  The flag is disabled by default.

Each header is only rebuilt if its prerequisite .java file changes.  The
new automake file, include/Makefile.am, contains the list of header
targets.

Currently the list consists of AWT-related headers.  Could someone who
is more familiar with the other areas of classpath that require JNI
headers complete the list?  Some headers should probably be removed.

Mark Wielaard suggested that anyone checking in changes to these headers
should use gcjh, since it is free and produces clean output.  If people
agree with this, I will regenerate the AWT-headers and check them in.

Comments?

Tom
