comex 2ba35cab73 Fix thread naming on Linux, which limits names to 15 bytes.
- In `SetCurrentThreadName`, when on Linux, truncate to 15 bytes, as (at
  least on glibc) `pthread_set_name_np` will otherwise return `ERANGE` and
  do nothing.
- Also, add logging in case `pthread_set_name_np` returns an error
  anyway.  This is Linux-specific, as the Apple and BSD versions of
  `pthread_set_name_np return `void`.
- Change the name for CPU threads in multi-core mode from
  "yuzu:CoreCPUThread_N" (19 bytes) to "yuzu:CPUCore_N" (14 bytes) so it
  fits into the Linux limit.  Some other thread names are also cut off,
  but I didn't bother addressing them as you can guess them from the
  truncated versions.  For a CPU thread, truncation means you can't see
  which core it is!

common: Port some changes from dolphin (#5127)
* IOFile: Make the move constructor and move assignment operator noexcept

Certain parts of the standard library try to determine whether or not a
transfer operation should either be a copy or a move. The prevalent notion
of move constructors/assignment operators is that they should not throw,
they simply move an already existing resource somewhere else.

This is typically done with 'std::move_if_noexcept'. Like the name says,
if a type's move constructor is noexcept, then the functions retrieves an
r-value reference (for move semantics), or an l-value (for copy semantics)
if it is not noexcept.

As IOFile deletes the copy constructor and copy assignment operators,
using IOFile with certain parts of the standard library can fail in
unexcepted ways (especially when used with various container
implementations). This prevents that.

* fix various instances of -1 being assigned to unsigned types

* do not assign in conditional statements

* File/IOFile: Check _tfopen_s properly

* common/file_util.cpp: address review comments

Port various minor changes from yuzu PRs (#4725)
* common/thread: Remove unused functions

Many of these functions are carried over from Dolphin (where they aren't
used anymore). Given these have no use (and we really shouldn't be
screwing around with OS-specific thread scheduler handling from the
emulator, these can be removed.

The function for setting the thread name is left, however, since it can
have debugging utility usages.

* input_common/sdl: Use a type alias to shorten declaration of GetPollers

Just makes the definitions a little bit more tidy.

* input_common/sdl: Correct return values within implementations of GetPollers()

In both cases, we weren't actually returning anything, which is
undefined behavior.

* yuzu/debugger/graphics_surface: Fill in missing surface format listings

Fills in the missing surface types that were marked as unknown. The
order corresponds with the TextureFormat enum within
video_core/texture.h.

We also don't need to all of these strings as translatable (only the
first string, as it's an English word).

* yuzu/debugger/graphics_surface: Clean up connection overload deduction

We can utilize qOverload with the signal connections to make the
function deducing a little less ugly.

* yuzu/debugger/graphics_surface: Tidy up SaveSurface

- Use QStringLiteral where applicable.

- Use const where applicable

- Remove unnecessary precondition check (we already assert the pixbuf
  being non null)

* yuzu/debugger/graphics_surface: Display error messages for file I/O errors

* core: Add missing override specifiers where applicable

Applies the override specifier where applicable. In the case of
destructors that are  defaulted in their definition, they can
simply be removed.

This also removes the unnecessary inclusions being done in audin_u and
audrec_u, given their close proximity.

* kernel/thread: Make parameter of GetWaitObjectIndex() const qualified

The pointed to member is never actually modified, so it can be made
const.

* kernel/thread: Avoid sign conversion within GetCommandBufferAddress()

Previously this was performing a u64 + int sign conversion. When dealing
with addresses, we should generally be keeping the arithmetic in the
same signedness type.

This also gets rid of the static lifetime of the constant, as there's no
need to make a trivial type like this potentially live for the entire
duration of the program.

* kernel/codeset: Make CodeSet's memory data member a regular std::vector

The use of a shared_ptr is an implementation detail of the VMManager
itself when mapping memory. Because of that, we shouldn't require all
users of the CodeSet to have to allocate the shared_ptr ahead of time.
It's intended that CodeSet simply pass in the required direct data, and
that the memory manager takes care of it from that point on.

This means we just do the shared pointer allocation in a single place,
when loading modules, as opposed to in each loader.

* kernel/wait_object: Make ShouldWait() take thread members by pointer-to-const

Given this is intended as a querying function, it doesn't make sense to
allow the implementer to modify the state of the given thread.

Lioncash a7a319cfd1 common/thread: Remove SleepCurrentThread()
This is also unused and superceded by standard functionality. The
standard library provides std::this_thread::sleep_for(), which provides
a much more flexible interface, as different time units can be used with
it.

Lioncash 61eafcee98 common/thread: Remove unused CurrentThreadId()
This is an old function that's no longer necessary. C++11 introduced
proper threading support to the language and a thread ID can be
retrieved via std::this_thread::get_id() if it's ever needed.

Emmanuel Gil Peyrot ebdae19fd2 Remove empty newlines in #include blocks.
This makes clang-format useful on those.

Also add a bunch of forgotten transitive includes, which otherwise
prevented compilation.
