For FTPS transfers, curl gets close_notify on the data connection
without that being a signal to close the control connection!

OpenSSL 1.1.0 adds SSL_CTX_set_<min|max>_proto_version() that we now use
when available. Existing code is preserved for older versions of
OpenSSL.
Closes#4304
SSL_VersionRangeGetDefault returns (TLSv1.0, TLSv1.2) as supported
range in NSS 3.45. It looks like the intention is to raise the minimum
version rather than lowering the maximum, so adjust accordingly. Note
that the caller (nss_setup_connect) initializes the version range to
(TLSv1.0, TLSv1.3), so there is no need to check for >= TLSv1.0 again.
Closes#4187

It was used (intended) to pass in the size of the 'socks' array that is
also passed to these functions, but was rarely actually checked/used and
the array is defined to a fixed size of MAX_SOCKSPEREASYHANDLE entries
that should be used instead.
Closes#4169
Several reasons:
- we can't add everyone who's helping out so its unfair to just a few
selected ones.
- we already list all helpers in THANKS and in RELEASE-NOTES for each
release
- we don't want to give the impression that some parts of the code is
"owned" or "controlled" by specific persons

Closes#4129
PK11_IsPresent() checks for the token for the given slot is available,
and sets needlogin flags for the PK11_Authenticate() call. Should it
return false, we should however treat it as an error and bail out.

The file suffix for dynamically loadable objects on macOS is .dylib,
which need to be added for the module definitions in order to get the
NSS TLS backend to work properly on macOS.

The value of the maxPTDs parameter to PR_Init() has since at least
NSPR 2.1, which was released sometime in 1998, been marked ignored
as is accordingly not used in the initialization code. Setting it
to a value when calling PR_Init() is thus benign, but indicates an
intent which may be misleading. Reset the value to zero to improve
clarity.
Closes https://github.com/curl/curl/pull/4054
Change the logic around such that we only keep CRLs that NSS actually
ended up caching around for later deletion. If CERT_CacheCRL() fails
then there is little point in delaying the freeing of the CRL as it
is not used.
Closes https://github.com/curl/curl/pull/4053
... since that needs UI_OpenSSL() which isn't provided when OpenSSL is
built with OPENSSL_NO_UI_CONSOLE which happens when OpenSSL is built for
UWP (with "VC-WIN32-UWP").

OpenSSL used to call exit(1) on syntax errors in OPENSSL_config(),
which is why we switched to CONF_modules_load_file() and introduced
a comment stating why. This behavior was however changed in OpenSSL
commit abdd677125f3a9e3082f8c5692203590fdb9b860, so remove the now
outdated and incorrect comment. The mentioned commit also declares
OPENSSL_config() deprecated so keep the current coding.

They serve very little purpose and mostly just add noise. Most of them
have been around for a very long time. I read them all before removing
or rephrasing them.

In Curl_multissl_version() it was possible to overflow the passed in
buffer if the generated version string exceeded the size of the buffer.
Fix by inverting the logic, and also make sure to not exceed the local
buffer during the string generation.

Older versions of OpenSSL report FIPS availabilty via an OPENSSL_FIPS
define. It uses this define to determine whether to publish -fips at
the end of the version displayed. Applications that utilize the version
reported by OpenSSL will see a mismatch if they compare it to what curl
reports, as curl is not modifying the version in the same way. This
change simply adds a check to see if OPENSSL_FIPS is defined, and will
alter the reported version to match what OpenSSL itself provides. This
only appears to be applicable in versions of OpenSSL <1.1.1
Closes#3771
Currently you can do things like --cert <(cat ./cert.crt) with (at least) the
openssl backend, but that doesn't work for nss because is_file rejects fifos.
I don't actually know if this is sufficient, nss might do things internally
(like seeking back) that make this not work, so actual testing is needed.
Closes#3807
As soon as a TLS backend gets ALPN conformation about the specific HTTP
version it can now set the multiplex situation for the "bundle" and
trigger moving potentially queued up transfers to the CONNECT state.
Without this, detecting and avoid reusing a closed TLS connection
(without a previous GOAWAY) when doing HTTP/2 is tricky.

Make functions no-ops if neither both USE_THREADS_POSIX and
HAVE_PTHREAD_H nor both USE_THREADS_WIN32 and HAVE_PROCESS_H are
defined. Previously, if only one of them was defined, there was either
code compiled that did nothing useful or the wrong header included for
the functions used.
Also, move POLARSSL_MUTEX_T define to implementation file as it's not
used externally.

AmiSSL is an Amiga native library which provides a wrapper over OpenSSL.
It also requires all programs using it to use bsdsocket.library
directly, rather than accessing socket functions through clib, which
libcurl was not necessarily doing previously. Configure will now check
for the headers and ensure they are included if found.
Closes#3677
Instead of using a fixed 256 byte buffer in the connectdata struct.
In my build, this reduces the size of the connectdata struct by 11.8%,
from 2160 to 1904 bytes with no functionality or performance loss.
This also fixes a bug in schannel's Curl_verify_certificate where it
called Curl_sspi_strerror when it should have called Curl_strerror for
string from GetLastError. the only effect would have been no text or the
wrong text being shown for the error.
