C++ nested classes, namespaces, structs, and compound statements

[Per Bothner]

Nothing much to add, except that namespace support is even
more critical for Java, in which *all* code uses namespaces
(aka "packages").  We kludge around it, by treating a compound
name like 'java.lang.Object' as a single name, but this doesn't
work all that well, especially with mixed Java/C++ code.  And
the primitive methods in Gcj are written in C++.

Fixing this mess is perhaps the most critical issue in terms
of improving Java support in gdb.

Java also has nested ("inner") classes.
