To sum up, this commit finishes FSTUB API implementation in the ReactOS kernel. This means one important thing: now ReactOS kernel knows about a bit about EFI and about GPT. No need to say that it's the first step into EFI support. But a lot more work is needed. Especially since the kernel is the only real entity in ReactOS to handle GPT. All the rest of the OS doesn't know anything about GPT.

A small note about FstubVerifyPartitionTableEFI(). This function is supposed to check whether a disk formated with GPT is valid, and if it's not, to fix it. First step is implemented. Second step isn't yet supported.

A general note about all that stuff: on GPT, backup table isn't properly handled for the moment, as ReactOS is experiencing disk geometry issues. That means it's not having the proper disk sectors count and then, can't find the backup table (which is located on last disk sector).
