This moves unsafe_block_from_ptr calls outside of the heap lock.

We assume here that concurrent call to another heap function on a block
being freed is undefined, and it should then be safe to do so:

* The block type or base offset never change after a block has been
  allocated and until it is freed.

* Block flags such as BLOCK_FLAG_LARGE, or BLOCK_FLAG_USER_INFO also
  never change after a block has been allocated.

* Other block flags are only read and modified inside the heap lock.

It's needed before is_inside_syscall accesses TEB.

We can't use NtCurrentTeb before setting %fs base.

This is used by clang to distinguish between MSVC and windows-itanium
targets. We override default option (usually meant for native builds)
to make sure that we use the right target.

-nostartfiles is not enough if clang is configured with explicit default rtlib.

-nostartfiles is not enough if clang is configured with explicit default rtlib.

The structure will be used to store printer information shared between all
printer handles (like printer name, attributes, job queue).

Having an extra layer of indirection here makes the code less clear.

More importantly it gets rid of the ERR since such failures are normal.

So it can async open with proper binding flags.

KWin has a switcher that triggered by Alt+Tab that basically acts like a pager. And hiding items in
the switcher is controlled by _KDE_NET_WM_STATE_SKIP_SWITCHER.
