Summary: [jni: fatal error (Local reference capacity exceeded)]

Initial Comment:
I'm trying to run an application that uses Soot. If I
try to process
too many classfiles at once, I get this error plus a
core dump:

  [jni: fatal error (Local reference capacity exceeded)]

This makes SableVM suddenly look like a "toy" Java VM when
we know it's really better than that :-)

SableVM should handle this situation more gracefully,
even if
it means an 'escape' mechanism that's slower than normal or
whatever.

Actually, a simpler way to fix this than using
EnsureCapacity() is to
use DeleteLocalRef() after assigning each parameter in the
array.
DeleteLocalRef() is already unimplemented.

See attached patch.

I think the 'correct' way to fix this is:

- Implement the JNI method EnsureCapacity()
- In sablevm.c, call (*env)->EnsureCapacity() to guarantee there
  will be at least as many local native references available as
  there are parameters to main().

Note: this happens if you give Sablevm more than 12 arguments
on the command line. For example:

$ sablevm 1 2 3 4 5 6 7 8 9 10 11 12 13
[jni: fatal error (Local reference capacity exceeded)]

This seems like a real bug, rather than an JNI limitation or
Classpath screwup.. (?)
