Gets rid some uses of the deprecated LocalBroadcastManager.
One note about the changes in GameFileCacheManager itself:
The change from compareAndSet to getValue followed by
setValue is actually safe, because startLoad and startRescan
only run from the main thread, and only the main thread ever
sets the flags to true. So it's impossible for any other thread
to change the flag in between the getValue and the setValue.
The past few Android releases have been adding restrictions
to what services are allowed to do, for the sake of stopping
services from using up too much battery in the background.
The IntentService class, which GameFileCacheService uses,
was even deprecated in Android 11 in light of this.
Typically, the reason why you would want use a service instead of
using a simple thread or some other concurrency mechanism from the
Java standard library is if you want to be able to run code in the
background while the user isn't using your app. This isn't actually
something we care about for GameFileCacheService -- if Android wants
to kill Dolphin there's no reason to keep GameFileCacheService
running -- so let's make it not be a service.
I'm changing this mainly for the sake of future proofing, but there
is one immediate (minor) benefit: Previously, if you tried to launch
Dolphin from Android Studio while your phone was locked, the whole
app would fail to launch because launching GameFileCacheService
wasn't allowed because Dolphin wasn't considered a foreground app.
These messages apply to the User directory regardless of
whether it's global or local, so we shouldn't specify "global".
Also changing "directory" to "folder", just for consistency
with "GC folder" in the same sentence.
This should make C++20 and std::filesystem work. (Not that
we really can use std::filesystem much on Android since
it doesn't work with scoped storage...)
We implement this by first rounding to nearest integer using the current
rouding mode, then converting this value from floating point to an integral
value.
Prefer using eax to isolate the sign bit. This saves a byte when the
destination ends up as r8-15, because those require a REX prefix.
Before:
41 8B C5 mov eax,r13d
41 C1 ED 1F shr r13d,1Fh
44 03 E8 add r13d,eax
41 D1 FD sar r13d,1
After:
41 8B C5 mov eax,r13d
C1 E8 1F shr eax,1Fh
44 03 E8 add r13d,eax
41 D1 FD sar r13d,1
This function was deprecated in ffmpeg in January[1], while its
replacement got introduced in 2015[2], so now might be the time to start
using it in Dolphin. :)

This moves the only direct call to zlib’s crc32() into its own
translation unit, but that operation is cold enough that this won’t
matter in the slightest. crc32_z() would be more appropriate, but
Android has an older zlib version…
This was originally intended to fix https://bugs.dolphin-emu.org/issues/12717 but this ended up not being the issue (instead it seems like files just weren't recompiled when imgui was updated due to MSVC weirdness). Still, using brackets instead of quotes is preferable as this is a library include.
