<mutex>: Implement mutex and recursive_mutex on SRW Lock. Support recursion only on recursive_mutex #654
Description
- correctness (constexpr construction)
- no undesired strengthening (recursion on non-recursive deliberately not behaving correctly)
- performance (no dynamic API binding => no control flow guard overhead; no recursion support overhead)
I expect it is already done in ABI-breaking branch.
vNext note: Resolving this issue will require breaking binary compatibility. We won't be able to accept pull requests for this issue until the vNext branch is available. See #169 for more information.
