To reduce the number `-Wunused-macro` compiler warnings:
- delete unused macros.
- comment out unused macro that are part of a set.
- move macros into the scope they are used.
This may be useful to enable by default, but there are tricky cases that
I didn't manage to fix and paused the effort. E.g. internal features
checks in `openssl.c`. There is more, once those are fixed.
Closes#16279
- drop version guard for `__inline`.
Supported since `_MSC_VER` 1000.
Visual C++, 32-bit, version 4.0 (1996)
- drop version guard for `__declspec(noreturn)` and `__forceinline`.
Supported since `_MSC_VER` 1200.
Visual C++, 32-bit, version 6.0 (1998)
For ancient versions, it's possible to override the default behaviour
by setting these macros via `CPPFLAGS`: `CURL_NORETURN`, `CURL_INLINE`,
`CURL_FORCEINLINE`
Closes#15946
Instead of redefining the `inline` keyword, introduce curl's own
`CURL_INLINE` macro and set it depending on the compiler's capabilities,
or use its value set via custom C flags.
Also keep honoring a custom `inline` macro, if set.
Closes#15523
`SHA512_256_BLOCK_SIZE`, `SHA512_256_DIGEST_SIZE` macros were both
defined within curl and also in the nettle library required by GnuTLS.
Fix it by namespacing the curl macros.

Based on the standards and guidelines we use for our documentation.
- expand contractions (they're => they are etc)
- host name = > hostname
- file name => filename
- user name = username
- man page => manpage
- run-time => runtime
- set-up => setup
- back-end => backend
- a HTTP => an HTTP
- Two spaces after a period => one space after period
Closes#14073
- Fix sha256 and sha512 duplicate macro names (eg function-like macro Ch
is now Sha256_Ch and Sha512_Ch).
- Avoid defining short defines like R, S. (eg S is now Sha256_S).
Closes https://github.com/curl/curl/pull/13751
This is a follow-up for PR #12897.
Add support for SHA-512/256 digest calculation by TLS backends.
Currently only OpenSSL and GnuTLS (actually, nettle) support
SHA-512/256.
Closes#13070
