- cmp-config.pl: add remaining exceptions. Sort list.
- drop unused `HAVE_SYS_WAIT_H`.

- drop unused `HAVE_FCHMOD`.

- autotools: stop promoting variables to macros:
`USE_NGTCP2_CRYPTO_*`, `USE_NGTCP2_H3`, `USE_OPENSSL_H3`,
`HAVE_LIBRESSL`.
They are not used in the source.
- cmake: drop unused `HAVE_O_NONBLOCK`,
`HAVE_DISABLED_NONBLOCKING`.
- lib: drop `NEED_MALLOC_H`.
It was used in manual-build cases for Amiga/MS-DOS/Windows/WinCE, but
never by autotools/cmake, thus apparently unnecessary.
- lib: drop unused `NEED_MEMORY_H`.
- lib: simplify classic mac feature guards,
drop `HAVE_EXTRA_STRICMP_H` and `HAVE_EXTRA_STRDUP_H`.
- autotools: drop unused `HAVE_GETHOSTBYNAME` detection.
- autotools: drop unused OpenSSL feature tests:
`HAVE_ERR_H`, `HAVE_PEM_H`, `HAVE_RSA_H`
- autotools: drop unused OpenSSL feature tests:
`HAVE_X509_H`, `HAVE_CRYPTO_H`, `HAVE_SSL_H`.
They performed a fallback check when the primary check missed
`openssl/x509.h`. Though if any other prefixed headers were found,
OpenSSL is already assumed detected.
The fallback check was looking for 3 unprefixed OpenSSL headers, and
if all found, marked OpenSSL found internally, but did not promote
it to `curl_config.h` via `USE_OPENSSL`. Meaning it either didn't do
anything or may have continued with an inconsistent state.
Added in d99c20f628 (2008)
At the time, there was an extra `AC_DEFINE(USE_SSLEAY, 1 ...` logic
after this code, which kicked in in the fallback case, but that code
was deleted in 709cf76f6b (2015)

- autotools: drop `AC_SUBST()` where the value is explicitly set anyway
and the macro is unused.
- autotools: replace `AC_SUBST(VAR, 1)` with local variable assigments,
where the `@VAR@` macro is unused. Also dedupe the local variable if
there was a parallel one used for the same purpose.
- autotools: drop local feature variables that were never used.
- autotools: drop unused `CURL_CHECK_OPTION_NTLM_WB`,
`CURL_CHECK_NTLM_WB`.
Also stop setting unused `NTLM_WB_ENABLED` macro for VMS.
