Make the Loader API thread-safe
...
Since the majority of the code is using ReadAt API already, map this to
a `readp` "syscall" which does not mutate any state about the file
descriptor therefore making it fairly safe multi-threading wise.
This allows to get rid of read-time mutexes in RamCachedFileLoader and
therefore fixes #9803

Big mutex overhaul - remove our custom ones, make them non-recursive where possible

android: Change preprocessor define to standard __ANDROID__

ANDROID is only standard to the old Makefile buildsystem, not the platform.

Add uncached flag for file loader reads.
...
This allows us to indicate that a read need not be cached.

http: Make sure we don't hang checking existence.
...
It's not great to delay loading when the server is down - we'll do a
proper check when we display the games.
This also fixes shutdown being slow.

Reduce load delay with many recent http files.
...
If we have data for them, we can start up fairly quickly.

Clamp reads at the beginning too.
...
Safer, avoids an index overrun in disk cache.

Fix reads from cache outside the file.
...
Homebrew seems to all trigger us to read after the end of file, which was
looping infinitely. Fixes #8773 .

Correct recovery of locked disk cache files.
...
We were keeping the index when creating a new file, rather than clearing
it. Additionally, flush before all reads - in case of overlap.

This prevents it from being corrupted due to a crash.

This way it will shrink to allow a few games to be cached simultaneously.
