The refactors are also required for https://github.com/bitcoin/bitcoin/pull/23438, but they are split up because the other pull doesn't compile with msvc right now. The third commit is not needed for the other pull, but still nice. ACKs for top commit: klementtan: reACK faa3ec2.

See [this comment](https://github.com/bitcoin/bitcoin/pull/19382#discussion_r446332852) for the reasoning behind the switch. -- Description from #19382: See [here](http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2018/p0936r0.pdf) for more detail on lifetimebound. This is implemented using preprocesor macros rather than configure checks in order to keep span.h self-contained. The ```[[clang::lifetimebound]]``` syntax was chosen over ```__attribute__((lifetimebound))``` because the former is more flexible and works to guard ```this``` as well as function parameters, and also because at least for now, it's available only in clang. There are currently no violations in our codebase, but this can easily be tested by inserting one like this somewhere and compiling with a modern clang: ```c++ Span<const int> bad(std::vector<int>{1,2,3}); ``` The result: > warning: temporary whose address is used as value of local variable 'bad' will be destroyed at the end of the full-expression [-Wdangling] Span<const int> bad(std::vector<int>{1,2,3}); ``` ACKs for top commit: sipa: ACK e3e7446305329ce96e9cf5f5161658eb2e1ea888 ajtowns: ACK e3e7446305329ce96e9cf5f5161658eb2e1ea888 (drive by; only a quick skim of code and some basic sanity checks) MarcoFalke: review ACK e3e7446305329ce96e9cf5f5161658eb2e1ea888 🔗 jonatack: ACK e3e7446 change since last review is adding `[[clang::lifetimebound]]` as `LIFETIMEBOUND` to src/attributes.h as suggested in https://github.com/bitcoin/bitcoin/pull/19387#issuecomment-650752959.

2020-07-30Add MakeUCharSpan, to help constructing Span<[const] unsigned char>Pieter Wuille
Based on a suggestion by Russell Yanofsky.
2020-07-19span: Add Span::empty() and use it in script/descriptorMarcoFalke
2020-06-29span: add lifetimebound attributeCory Fields
See http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2018/p0936r0.pdf for reference. This helps to guard against dangling references caused by construction from temporaries such as: Span<const int> sp(std::vector<int>{1,2,3});
2020-06-29span: (almost) match std::span's constructor behaviorCory Fields
c++20's draft of std::span no longer includes move constructors.

2020-05-12Add Span constructors for arrays and vectorsPieter Wuille
2020-05-12Make pointer-based Span construction saferPieter Wuille
This prevents constructing a Span<A> given two pointers into an array of B (where B is a subclass of A), at least without explicit cast to pointers to A.
2020-05-12Make Span size type unsignedPieter Wuille
This matches a change in the C++20 std::span proposal.
