Support latent and delayed symbols

Neither latent, nor delayed symbols are given a breakpoint.  The difference
is in who's responsible for the state.  Latent symbols are (will be) used
by ltrace core.  Delayed symbols are used by backends.  Only when both of
these flags are cleared is a breakpoint enabled for the symbol.
