We mustn't use m_system when it is nullptr. This was causing Dolphin to
crash on Android whenever an activity was recreated or resumed while
emulation is running, which is super common.
Prototype of a system to whitelist known game patches that are allowed to be used while RetroAchievements Hardcore mode is active. ApprovedInis.txt contains known hashes for the ini files as they appear in the repo, and can be compared to the local versions of these files to ensure they have not been edited locally by the player. ApprovedInis.txt is hashed and verified similarly first, with its hash residing as a const string within AchievementManager.h, ensuring ApprovedInis and the hashes within cannot be modified without editing Dolphin's source code and recompiling completely.
The challenge popups have proven to be excessive and are no longer useful thanks to the achievements hotkey. Instead, those events will ask for an immediate RP-level update to the achievements dialog, which will among other things re-sort the dialog to show challenges on top faster.
This way, by pressing Continue on top of a breakpoint, the emulation will actually continue (like on Cached Interpreter and JIT), instead of doing nothing.
Before:
1. In theory there could be multiple, but in practice they were (manually) cleared before creating one
2. (Some of) the conditions to clear one were either to reach it, to create a new one (due to the point above), or to step. This created weird behavior: let's say you Step Over a `bl` (thus creating a temporary breakpoint on `pc+4`), and you reached a regular breakpoint inside the `bl`. The temporary one would still be there: if you resumed, the emulation would still stop there, as a sort of Step Out. But, if before resuming, you made a Step, then it wouldn't do that.
3. The breakpoint widget had no idea concept of them, and will treat them as regular breakpoints. Also, they'll be shown only when the widget is updated in some other way, leading to more confusion.
4. Because only one breakpoint could exist per address, the creation of a temporary breakpoint on a top of a regular one would delete it and inherit its properties (e.g. being log-only). This could happen, for instance, if you Stepped Over a `bl` specifically, and pc+4 had a regular breakpoint.
Now there can only be one temporary breakpoint, which is automatically cleared whenever emulation is paused. So, removing some manual clearing from 1., and removing the weird behavior of 2. As it is stored in a separate variable, it won't be seen at all depending on the function used (fixing 3., and removing some checks in other places), and it won't replace a regular breakpoint, instead simply having priority (fixing 4.).
Now it actually does what it says on the name, instead of creating a breapoint and doing nothing else (not even updating the widget).
Also, it now can't be selected if emulation isn't running.

Change misleading names.
Fix function usage: Intepreter and Step Out will not check breakpoints in their own wrong way anymore (e.g. breaking on log-only breakpoints).
There are two pieces of functionality to be added here. One, we want to disallow pausing too frequently, as it may be used as an artificial slowdown. This is handled within the client, which can tell us if a pause is allowed. Two, we want to call rc_client_idle on a periodic basis so the connection with the server can be maintained even while the emulator is paused.
When the immediate value is zero, we can do a negation. On ARM64 the NEG
/NEGS instructions are just an alias for SUB/SUBS with a hardcoded WZR.
Before:
```
ldr w22, [x29, #0x28]
mov w21, #0x0 ; =0
subs w22, w21, w22
```
After:
```
ldr w22, [x29, #0x28]
negs w22, w22
```
This reverts commit 72cf2bdb87f09deff22e1085de3290126aa4ad05.
SYSCONF settings are getting cleared when they shouldn't be. Let's
revert the change until I get proper time to figure out why it's broken.
rc_client calls the provided memory peeker asynchronously in the callback for starting a session, to validate/invalidate the memory used for achievements. Dolphin cannot access memory from any thread but host or CPU so this access has a small chance of being invalid. This commit adds a MemoryVerifier that the AchievementManager will use to perform this, before changing the peek method back to the original MemoryPeeker for normal operation.
Some pieces of code are calling IsRunning because there's some
particular action that only makes sense when emulation is running, for
instance showing the state of the emulated CPU. IsRunning is appropriate
to use for this. Then there are pieces of code that are calling
IsRunning because there's some particular thing they must avoid doing
e.g. when the CPU thread is running or IOS is running. IsRunning isn't
quite appropriate for this. Such code should also be checking for the
states Starting and Stopping. Keep in mind that:
* When the state is Starting, the state can asynchronously change to
Running at any time.
* When we try to stop the core, the state gets set to Stopping before we
take any action to actually stop things.
This commit adds a new method Core::IsUninitialized, and changes all
callers of IsRunning and GetState that look to me like they should be
changed.
Core::GetState reads from four different pieces of state: s_is_stopping,
s_hardware_initialized, s_is_booting, and CPUManager::IsStepping.
I'm keeping that last one as is for now because there's code in Dolphin
that sets it directly, but we can unify the other three to make things
easier to reason about.
This commit also gets rid of s_is_started. This was previously used in
Core::IsRunningAndStarted to ensure true wouldn't be returned until the
CPU thread was started, but it wasn't used in Core::GetState, so
Core::GetState would happily return State::Running after we had
initialized the hardware but before we had initialized the CPU thread.
As far as I know, there are no callers that have any real need to know
whether the boot process is currently initializing the hardware or the
CPU thread. Perhaps once upon a time there was a desire to make the
apploader debuggable, but a long time has passed without anyone stepping
up to implement it, and the way CBoot::RunApploader is implemented makes
it rather difficult. So this commit makes all the functions in Core.cpp
consider the core to still be starting until the CPU thread is started.
Since rcheevos headers are included in AchievementManager.h, and everyone that depends on Core can include that, we must also pass on the include directory and defines to those dependencies
If an icon is displayed on screen before it downloads, it was displaying a default icon but it would fail to load the actual icon even after it was downloaded. This fixes that.
Add a two second timer to Achievement Progress Indicators to wait until two seconds after the previous message (when it should have decayed out automatically) before posting any new ones.
AchievementManager maintains a unique pointer to a copy of the current volume so it can asynchronously hash that volume. It is not needed otherwise, so I can release that pointer when hashing is complete. This change fixes a bug whereby changing discs in a game and then changing to a different game would result in the loaded volume pointer still being loaded with and hashing to the previous game.
