A custom `HAVE_GETADDRINFO` check came with the initial CMake commit
[1]. A later commit [2] added a standard check for it as well. The
standard check run before the custom one, so CMake ignored the latter.
The custom check was also non-portable, so this patch deletes it in
favor of the standard check.

Enable `HAVE_UNISTD_H`, `HAVE_STRTOK_R` and `HAVE_STRCASECMP` detection
on Windows, instead of having predefined values.
With these features detected correctly, CMake Windows builds get closer
to the autotools and `config-win32.h` ones.
This also fixes detecting `HAVE_FTRUNCATE` correctly, which required
`unistd.h`.
Fixing `ftruncate()` in turn causes a build warning/error with legacy
MinGW/MSYS1 due to an offset type size mismatch. This env misses to
detect `HAVE_FILE_OFFSET_BITS`, which may be a reason. This patch
force-disables `HAVE_FTRUNCATE` for this platform.

Detecting headers and lib separately makes sense when headers come in
variations or with extra ones, but this wasn't the case here. These were
duplicate/parallel macros that we had to keep in sync with each other
for a working build. This patch leaves a single macro for each of these
dependencies:
- Rely on `HAVE_LIBZ`, delete parallel `HAVE_ZLIB_H`.
Also delete CMake logic making sure these two were in sync, along with
a toggle to turn off that logic, called `CURL_SPECIAL_LIBZ`.
Also delete stray `HAVE_ZLIB` defines.
There is also a `USE_ZLIB` variant in `lib/config-dos.h`. This patch
retains it for compatibility and deprecates it.
- Rely on `USE_LIBSSH2`, delete parallel `HAVE_LIBSSH2_H`.
Also delete `LIBSSH2_WIN32`, `LIBSSH2_LIBRARY` from
`winbuild/MakefileBuild.vc`, these have a role when building libssh2
itself. And `CURL_USE_LIBSSH`, which had no use at all.
Also delete stray `HAVE_LIBSSH2` defines.
- Rely on `USE_LIBSSH`, delete parallel `HAVE_LIBSSH_LIBSSH_H`.
Also delete `LIBSSH_WIN32`, `LIBSSH_LIBRARY` and `HAVE_LIBSSH` from

This is the single place in libcurl code where it uses the "native"

1. Re-enable `HAVE_GETADDRINFO` detection on Windows
Commit d08ee3c83d (in 2013) added logic
that automatically assumed `getaddrinfo()` to be present for builds
with IPv6 enabled. As it turns out, certain toolchains (e.g. original
MinGW) by default target older Windows versions, and thus do not
support `getaddrinfo()` out of the box. The issue was masked for
a while by CMake builds forcing a newer Windows version, but that
logic got deleted in commit 8ba22ffb20.
Since then, some CI builds started failing due to IPv6 enabled,
`HAVE_GETADDRINFO` set, but `getaddrinfo()` in fact missing.
It also turns out that IPv6 works without `getaddrinfo()` since commit
67a08dca27 (from 2019, via #4662). So,
to resolve all this, we can now revert the initial commit, thus
restoring `getaddrinfo()` detection and support IPv6 regardless of its
outcome.

2. Omit `bcrypt` with original MinGW
Original (aka legacy/old) MinGW versions do not support `bcrypt`
(introduced with Vista). We already have logic to handle that in
`lib/rand.c` and autotools builds, where we do not call the
unsupported API and do not link `bcrypt`, respectively, when using
original MinGW.
This patch ports that logic to CMake, fixing the link error:
`c:/mingw/bin/../lib/gcc/mingw32/9.2.0/../../../../mingw32/bin/ld.exe: cannot find -lbcrypt`

This patch makes CMake fill the "OS string" with the value of
`CMAKE_C_COMPILER_TARGET`, if passed. This typically contains a triplet,
the same we can pass to `./configure` via `--host=`.
For non-CMake, non-autotools, Windows builds, this patch adds the ability
to override the default `OS` value in `lib/config-win32.h`.
With these its possible to get the same OS string across the three build
systems.
This patch supersedes the earlier, partial, CMake-only solution:
435f395f3f, thus retiring the
`CURL_OS_SUFFIX` CMake option.

The goal of this patch is to avoid CMake forcing specific Windows
versions and rely on toolchain defaults or manual selection instead.
This gives back control to the user. This also brings CMake closer to
how autotools and `Makefile.m32` behaves in this regard.
- CMake had a setting `ENABLE_INET_PTON` defaulting to `ON`, which did
nothing else than fixing the Windows build target to Vista. This also
happened when the toolchain did not have Vista support (e.g. original
MinGW), breaking such builds.
In other environments it did not make a user-facing difference,
because libcurl has its own pton() implementation, so it works well
with or without Vista's inet_pton().
This patch drops this setting. inet_pton() is now used whenever
building for Vista or newer, either when requested manually or by
default with modern toolchains (e.g. mingw-w64). Older envs will fall
back to curl's pton().

- When the user did no select a Windows target version manually, stop
explicitly targeting Windows XP, and instead use the toolchain default.
This may pose an issue with old toolchains defaulting to pre-XP
targets. In such case you must manually target Windows XP via:
`-DCURL_TARGET_WINDOWS_VERSION=0x0501`
or
`-DCMAKE_C_FLAGS=-D_WIN32_WINNT=0x0501`

- 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.

- Change normaliz lib name to all lowercase.
This is from a standing patch in vcpkg:

- Prevent CMake to auto-detect /dev/urandom when cross-building.
Before this patch, it would detect it in a cross-build scenario on *nix
hosts with this device present. This was a problem for example with
Windows builds, but it could affect any target system with this device
missing. This also syncs detection behaviour with autotools, which also
skips it for cross-builds.
- Also, make sure to never use the file RANDOM_FILE as entropy for libcurl's
fallback random number generator on Windows. Windows does not have the
concept of reading a random stream from a filename, nor any guaranteed
non-world-writable path on disk. With this, a manual misconfiguration or
an overeager auto-detection can no longer result in a user-controllable
seed source.
