Increase test coverage for ELF-related tables
Add additional test RPMs
database: Use pg_put_copy for most Java loading operations
database::add_elf_image(): Minor reformatting
cxxll::pg_put_copy::pg_put_copy_base: Use pgresult_handle::binaryTuples()
cxxll::pgresult_handle::nfields(): New member function
cxxll::pg_put_copy::pg_put_copy_base: Additional error handling
cxxll::assertion_error: New class

And an assert macro.
cxxll::pg_put_copy: Switch to cxxll::assert
database: Switch to cxxll::assert
database: Begin switching ELF loading to COPY mode
database: Switch most of the ELF loading to COPY statements
cxxll::pg_put_copy::row_1(): Drop unnecessary template parameters
cxxll::pg_prepared: Return pgresult_handle objects
symboldb integration test: Record test success
cxxll::elf_image::symbol_range::state::next_section(): Only process .dynsym
Add debuginfo test RPM
cxxll::elf_debuglink: New class
cxxll::elf_image::debuglink(): New member function
symboldb integration test: Check for ELF errors
