- Use the Windows API to seed the fallback random generator. This ensures to always have a random seed, even when libcurl is built with a vtls backend lacking a random generator API, such as rustls (experimental), GSKit and certain mbedTLS builds, or, when libcurl is built without a TLS backend. We reuse the Windows-specific random function from the Schannel backend. - Implement support for `BCryptGenRandom()` [1] on Windows, as a replacement for the deprecated `CryptGenRandom()` [2] function. It is used as the secure random generator for Schannel, and also to provide entropy for libcurl's fallback random generator. The new function is supported on Vista and newer via its `bcrypt.dll`. It is used automatically when building for supported versions. It also works in UWP apps (the old function did not). - Clear entropy buffer before calling the Windows random generator. This avoids using arbitrary application memory as entropy (with `CryptGenRandom()`) and makes sure to return in a predictable state when an API call fails.
