core: Inline mallocing wrapper functions

As far as I can tell, this doesn't make rust compile any
faster, but it does at least remove one level of indirection
on malloc, which might help speed up some operations.
std: change Decoder::read_option to return a generic type

This allows read_option to be used with a custom option type instead
of just core::Option.
