RFR: 8306949: Resolve miscellaneous multiple symbol definition issues when statically linking JDK/VM natives with standard launcher

[Jiangli Zhou]

Resolve misc symbol issues observed when statically linking JDK/VM natives with the standard Java launcher executable. Use the same approaches adopted by earlier fixes for static linking related symbol problems (e.g. JDK-8306033):

- Change findFunction() to be a static function in src/java.smartcardio/unix/native/libj2pcsc/pcsc_md.c.
- Rename findFunction() to p11FindFunction() in libj2pkcs11 code.
- Rename 'debug' to 'debug_j2pkcs11' in libj2pkcs11 code.
- Rename 'jvm' to 'jvm_xawt' in libawt_xawt code.
