some symbols in X_db_search_symbol(). Reject the same symbols that
rev.1.13 did (all except STT_OBJECT and STT_FUNC), except don't reject
typeless symbols. This keeps the typeless symbols in non-verbosely
written assembler code visible, but makes file symbols invisible. ELF
file symbols have type STT_FILE and value 0, so this stops small values
and offsets sometimes being displayed in terms of the first file symbol
in the kernel (usually device_if.c). I think it rejects some other
unwanted symbols (small absolute symbols for things like struct offsets).
It may reject some wanted symbols (large absolute symbols for addresses
like PTmap).
