Adds the barebones enumeration constants and functions in place to handle memory attributes, while also essentially leaving the attribute itself non-functional.

We can hide the direct array from external view and instead provide functions to retrieve the necessary info. This has the benefit of completely hiding the makeup of the SinkDetails structure from the rest of the code. Given that this makes the array hidden, we can also make the array constexpr by altering the members slightly. This gets rid of several static constructor calls related to std::vector and std::function. Now we don't have heap allocations here that need to occur before the program can even enter main(). It also has the benefit of saving a little bit of heap space, but this doesn't matter too much, since the savings in that regard are pretty tiny.

svcQueryProcessMemory is trivial to implement, given all the behavior necessary for it is present, it just needs a handler for it.

In the previous change, the memory writing was moved into the service function itself, however it still had a problem, in that the entire MemoryInfo structure wasn't being written out, only the first 32 bytes of it were being written out. We still need to write out the trailing two reference count members and zero out the padding bits. Not doing this can result in wrong behavior in userland code in the following scenario: MemoryInfo info; // Put on the stack, not quaranteed to be zeroed out. svcQueryMemory(&info, ...); if (info.device_refcount == ...) // Whoops, uninitialized read. This can also cause the wrong thing to happen if the user code uses std::memcmp to compare the struct, with another one (questionable, but allowed), as the padding bits are not guaranteed to be a deterministic value. Note that the kernel itself also fully zeroes out the structure before writing it out including the padding bits.

Moves the memory writes directly into QueryProcessMemory instead of letting the wrapper function do it. It would be inaccurate to allow the handler to do it because there's cases where memory shouldn't even be written to. For example, if the given process handle is invalid. HOWEVER, if the memory writing is within the wrapper, then we have no control over if these memory writes occur, meaning in an error case, 68 bytes of memory randomly get trashed with zeroes, 64 of those being written to wherever the memory info address points to, and the remaining 4 being written wherever the page info address points to. One solution in this case would be to just conditionally check within the handler itself, but this is kind of smelly, given the handler shouldn't be performing conditional behavior itself, it's a behavior of the managed function. In other words, if you remove the handler from the equation entirely, does the function still retain its proper behavior? In this case, no. Now, we don't potentially trash memory from this function if an invalid query is performed.

These should be swapped.

This would result in svcSetMemoryAttribute getting the wrong value for its third parameter. This is currently fine, given the service function is stubbed, however this will be unstubbed in a future change, so this needs to change.

The kernel returns a memory info instance with the base address set to the end of the address space, and the size of said block as 0 - address_space_end, it doesn't set both of said members to zero.

Gets rid of the need to directly access the managed VMAs outside of the memory manager itself just for querying memory.

Gets the two structures out of an unrelated header and places them with the rest of the memory management code. This also corrects the structures. PageInfo appears to only contain a 32-bit flags member, and the extra padding word in MemoryInfo isn't necessary.

Amends the MemoryState enum to use the same values like the actual kernel does. Also provides the necessary operators to operate on them. This will be necessary in the future for implementing svcSetMemoryAttribute, as memory block state is checked before applying the attribute.

The Process object kept itself alive indefinitely because its handle_table contains a SharedMemory object which owns a reference to the same Process object, creating a circular ownership scenario. Break that up by storing only a non-owning pointer in the SharedMemory object.

fmt::format() returns a std::string instance by value, so calling .c_str() on it here is equivalent to doing: auto* ptr = std::string{}.c_str(); The data being pointed to isn't guaranteed to actually be valid anymore after that expression ends. Instead, we can just take the string as is, and provide the necessary formatting parameters.

This constant is related to the size of the instruction.

The previous code would cause a warning, as it was truncating size_t (64-bit) to a u32 (32-bit) implicitly.

Based off RE, the backing code only ever seems to use 0-2 as the range of values 1 being a generic log enable, with 2 indicating logging should go to the SD card. These are used as a set of flags internally. Given we only care about receiving the log in general, we can just always signify that we want logging in general.
