Expose the size of the table in the ObjectSymbolTable trait

[sfackler]

It looks like all of the symbol table implementations expose a length method. It would be great to propagate that up to the read::SymbolTable.

Note that for some formats this length includes auxiliary symbols, so it would be a hint rather than an exact length.

[sfackler]

Oh interesting. What I'm really after is the ability to directly binary search on the table for the symbol corresponding to an address rather than having to load all of the symbols into a different data structure. I believe this is doable on ELF objects at least. Is that not possible in other formats?

[philipc]

COFF and XCOFF both have auxiliary symbols, and you can't determine which symbols are auxiliary without parsing in order.
