This will be required for permission checks in the future.
Note that this is only for the PPC as we do not have actual processes.
Keeping track of other modules' UIDs/GIDs is virtually useless anyway.
UID/GID changes are implemented in the following functions:
* ES_Launch
* ES_DIVerify
ES_SetUid is not implemented yet because it'd need further changes.
Fixes warnings:

Dolphin assumes that content 0 is opening.bnr, without checking
whether content 0 exists or if it is even supposed to be there (it's
only there for channels). This results in sometimes reading garbage.
This adds a check to only try to read names from content 0's header
if the title is a channel (channel, system channel or game channel).
The Tools > Load System Menu option displays the version of the
installed Wii Menu. This commit changes the way we display that
version, like so: "Load System Menu 514P" -> "Load System Menu 4.3E"
The numbers are from http://wiibrew.org/wiki/System_Menu
5.0-2712 made ES's code for setting the game ID use the
title ID converted to hex (except for disc titles) instead
of using a 6-char game ID like before. Then, 5.0-2830 made
us use that code even when loading game INIs. This breaks the
expectations of both users and the game INIs we ship with.
This commit makes Dolphin use 6-char game IDs for all
titles (unless the 6-char ID would contain unprintable
characters, which is the case with e.g. the Wii Menu).
I'm also putting unprintability checks in VolumeWad
for consistency.
Advantages:
* Simpler code in general
* No extra volume objects created
* Now actually notices if the disc or partition gets
changed while the core is running
* No longer picks up on disc access done by the GUI
(it used to do so as long as the core was running)
* Gets rid of a Core dependency in DiscIO
There are two performance disadvantages:
* FileMonitor is now a bit slower when used with VolumeDirectory
because FileMonitor now always uses the FileSystemGCWii code
for finding filenames instead of VolumeDirectory finding the
filename on its own and directly hooking into FileMonitor.
But this isn't such a big deal, because it's happening on the
DVD thread, and my currently unmerged file system PR will make
FileSystemGCWii's file finding code about as fast as
VolumeDirectory's.
* FileMonitor's creation of the file system object is now
done on the CPU thread instead of the DVD thread, and
it will be done even if FileMonitor logging is disabled.
This will be fixed in the next commit.
There's no point in creating a volume without a blob,
since essentially all the functionality of a volume
requires a blob to be used.
Also, VolumeCreator doesn't support creating volumes
without blobs (it can't even figure out the volume type
unless it gets a blob), so it's currently impossible
for a volume to be created without a blob.
Most of the Volume code was written before this
convenience function was added. Let's use it more.
Also deleting m_pReader nullptr checks that are
unnecessary because of Read (which ReadSwapped calls)
already having a nullptr check.
This moves all the byte swapping utilities into a header named Swap.h.
A dedicated header is much more preferable here due to the size of the
code itself. In general usage throughout the codebase, CommonFuncs.h was
generally only included for these functions anyway. These being in their
own header avoids dumping the lesser used utilities into scope. As well
as providing a localized area for more utilities related to byte
swapping in the future (should they be needed). This also makes it nicer
to identify which files depend on the byte swapping utilities in
particular.
Since this is a completely new header, moving the code uncovered a few
indirect includes, as well as making some other inclusions unnecessary.
This changes ES to keep track of the active title properly,
just like IOS:
* It is NOT changed on resource manager open/close.
* It is reset on IOS reload.
* It is changed by ES_DIVerify and ES_Launch.
IOS stores the active title in a structure like this:
struct ESTitleContext
{
Ticket* ticket;
TMD* tmd;
u32 active;
};
With this commit, we also do keep the Ticket and TMD around. This
makes some of the DI ioctlvs (which return data about the current
active title) trivial to implement in the future.
This fixes the System Menu not being able to see update partitions
and also allows us to change Dolphin's active game info in the future.
We already have a TMDReader, so let's actually use it.
And move ESFormats to IOS::ES, since it's definitely part of IOS.
This adds a DiscIO dependency on Core which will be fixed in a
follow-up PR.
This prevents Dolphin from writing to /sys/uid.sys (on the host; root
partition) when installing a WAD before starting emulation, because
the session root is not initialized at that moment.
Incidentally, this also gets rid of a singleton.
This fixes a regression from 5.0-1556, but I don't know why
the regression occurred or why this fixes it. (Many games
failed to fully boot - I tried Metroid Prime and Twilight
Princess (both GC), and they never got to the title screen.)
