Add the libdb2 type-existence tests to the top-level configure script.

Replace the generated header files in db2 with static ones that
include autoconf.h and make decisions based on the macros defined
there.  Omit some tests that test for things we assume now, like
"const" working and "size_t" being defined.  Update dependencies.

The libdb2 configure script now generates no header files.
