Now that we've dropped MSVC 2015, I believe we can rely on C++14 (which
is now seven years old). This switches the build to require C++14. I've
gone ahead and switched code in both public headers and within the
library, but if the public headers are a problem, we can revert those
separately.
C++14 doesn't get us quite as much as C++17, but see if we can get to
C++14 first. Still, std::enable_if_t and the less restricted constexpr
are nice wins.
Update-Note: C++14 is now required to build BoringSSL. If the build
breaks, make sure your compiler is C++14-capable and is not passing
-std=c++11. If this is causing problems for your project, let us know.

VS 2017 was released in March 2017, five years ago now. This means VS
2015 is now past our support window.
This will make the unmarked and "vs2017" configs in CI/CQ do the same
thing. I'll follow up with a separate CL in infra/config to switch the
test VS 2019 instead.
Update-Note: BoringSSL may no longer build with VS 2015. Consumers
should upgrade to the latest Visual Studio release. VS 2017 or later is
required.

Although we defined a CBS -> Span<const uint8_t> conversion, MSVC 2015
keeps trying to call the Span(const Container&) constructor. It seems to
not correctly SFINAE the existence of data() and size() members unless
the expression is inlined into the default template argument.

absl::Span, base::span, and std::span have first() and last() methods
which give prefixes and suffixes. first() just saves 5 characters, but
last() is nicer to write than subspan() for suffixes.
Unlike subspan(), they also do not have clipping behavior, so we're
guaranteed the length is correct. The clipping behavior comes from
absl::Span::subspan() and is not present in std::span or base::span.
I've left it in, in case we switch to absl::Span in the future, but I
imagine absl::Span will need to migrate this at some point.

The headers aren't quite interchangeable. stdlib.h defines ::abort()
while cstdlib defines std::abort(). The Google style guide doesn't give
much guidance but says to match the existing style, so I've switched it
to stdlib.h.
