loader: add rom transaction API
Image file loaders may add a series of roms. If an error occurs partway
through loading there is no easy way to drop previously added roms.
This patch adds a transaction mechanism that works like this:
rom_transaction_begin();
...call rom_add_*()...
rom_transaction_end(ok);
If ok is false then roms added in this transaction are dropped.
