This is implemented as an output streaming stack of unencoders, the last
calling the client write procedure.

New test 230 checks this feature.

Bug: https://github.com/curl/curl/pull/2002
Reported-By: Daniel Bankhead

Since CURLSSH_AUTH_ANY (aka CURLSSH_AUTH_DEFAULT) is ~0 an arg value
check on this option is incorrect; we have to accept any value.

Prior to this change since f121575c (7.56.1+) CURLOPT_SSH_AUTH_TYPES
erroneously rejected CURLSSH_AUTH_ANY with CURLE_BAD_FUNCTION_ARGUMENT.

It triggers an assert() when built with memdebug since malloc(0) may
return NULL *or* a valid pointer.

By properly keeping track of the last entry in the list of URLs/uploads
to handle, curl now avoids many meaningless traverses of the list which
speeds up many-URL handling *MASSIVELY* (several magnitudes on 100K
URLs).

Added test 1291, to verify that it doesn't take ages - but we don't have
any detection of "too slow" command in the test suite.

Fixes #2047

Prior to this change since f121575c (7.56.1+) CURLOPT_DNS_CACHE_TIMEOUT
erroneously rejected -1 with CURLE_BAD_FUNCTION_ARGUMENT.

This caused the torture tests on test 1800 to fail.

Test cleanup after OOM wasn't being consistently performed.

... which is valid according to documentation. Regression since
f121575c.

Verified now in test 501.

The config files define curl and libcurl targets as imported targets
CURL::curl and CURL::libcurl. For backward compatibility with CMake-
provided find-module the CURL_INCLUDE_DIRS and CURL_LIBRARIES are
also set.

"PR-welcome" was the former name.

If WINAPI_FAMILY is defined, it should be safe to try to include
winapifamily.h to check what the define evaluates to.

This should fix detection of CURL_WINDOWS_APP if building with
_WIN32_WINNT set to 0x0600.

- When uploading via chunked-encoding don't compare file size to bytes
  sent to determine whether the upload has finished.

Chunked-encoding adds its own overhead which why the bytes sent is not
equal to the file size. Prior to this change if a file was uploaded in
chunked-encoding and its size was known it was possible that the upload
could end prematurely without sending the final few chunks. That would
result in a server hang waiting for the remaining data, likely followed
by a disconnect.

The scope of this bug is limited to some arbitrary file sizes which have
not been determined. One size that triggers the bug is 475020.
