Now returns a copy of the removed kv instead of a pointer to the removed kv. The removed kv gets overwritten when shifting the hash map after the removal, so returning a pointer to it will have another kv's values in it after the return.
This bug had some nasty downstream effects in things like BufSet and BufMap where delete would free a still in-use KV and leave the actually removed KV un-free'd.
Documentation comments copied here:
On Linux, it is possible that the thread spawned with `spawnThread`
finishes executing entirely before the clone syscall completes. In this
case, `std.os.Thread.handle` will return 0 rather than the
no-longer-existing thread's pid.
* Fixes to divsf3
Embarrassingly failed to notice a section that was unchanged from where
it was copied from mulXf3.zig. The test cases for this function series
div{s,d,t}f3 are very incomplete and don't exercise all code paths.
Remove unnecessary switch from divsf3 left during development from when
I tried to make it generic to support f32, f64, and f128 in one go.
Make runtime safety dependent on whether a test is being run.
* divsf3: switch plus to minus
This fixes comes thanks to Rich Felker from the musl libc project,
who gave me this crucial information:
"to satisfy the abi, your init code has to write the same value
to that memory location as the value passed to the [arch_prctl]
syscall"
This commit also changes the rules for when to build statically
by default. When building objects and static libraries, position
independent code is disabled if no libraries will be dynamically
linked and the target does not require position independent code.

It is sometimes useful to skip generating of the header file (e.g. https://github.com/ziglang/zig/issues/2173), and zig compiler provides an option `--disable-gen-h` to control that behaviour. However, setting `lib.disable_gen_h = true` in a typical `build.zig` didn't append the option to arguments. This commit fixes it and adds a convenient `setDisableGenH` setter.
