> Pepper: Fix crash on allocation failure.

> GetPNaClResourceInfo() currently performs a 1 megabyte allocation. Though any
> memory allocation can fail, this one is more likely due to its size.
> 
> This change mitigates this problem in two ways. If memory allocation fails, we
> report an error and return early instead of using memory.
> 
> Additionally, this change checks the size of the file before performing a
> memory allocation. This should lead to smaller allocations and more successful
> plugin loads.
