Clang-format: make format is now multithreaded.

Clang-format: Wrap brace after Objective-C declaration

Makes those behave similar to C/C++ functions.

Clang-format: half-indent access modifier

We definitely shouldn't use a regular indent for it.

The half one (which is a single space in this case) might
not be so well visible, but kind of helps reading that it
is inside a class.

Clang-format: Indent the constructor initializer

Makes it easier to read what is an initialzier and what is the code,
adding some space to the initialization.

Clang-format: Don't line break after class

One can think of a class as a structure with different
default visibility.

Point is: in C++ code it will be weird to see different
rules for classes and structures.

Clang-format: Make it easier to tweak running command

Allows to compare behavior of various clang-format versions.

Use 4 spaces for continuations, addresses T53211#611987

Before:

```
if (
psmd->mesh_final->totvert != psmd->totdmvert || psmd->mesh_final->totedge != psmd->totdmedge ||
psmd->mesh_final->totface != psmd->totdmface) {
psys->recalc |= ID_RECALC_PSYS_RESET;

psmd->totdmvert = psmd->mesh_final->totvert;
psmd->totdmedge = psmd->mesh_final->totedge;
psmd->totdmface = psmd->mesh_final->totface;
}
```

After:

```
if (psmd->mesh_final->totvert != psmd->totdmvert ||
psmd->mesh_final->totedge != psmd->totdmedge ||
psmd->mesh_final->totface != psmd->totdmface)
{
psys->recalc |= ID_RECALC_PSYS_RESET;

psmd->totdmvert = psmd->mesh_final->totvert;
psmd->totdmedge = psmd->mesh_final->totedge;
psmd->totdmface = psmd->mesh_final->totface;
}
```

Test not aligning escaped newlines

They're annoying to edit if you ever dont have auto-formatting enabled
and with 100 char width, they may run off the screen.

Fix expanding tabs for 2 space indentation.

Use 2 space indent, brace on same line
