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.

Removed done stuff. Removed entries no longer considered for the near
term.

Closes #2028

returning 'time_t' is problematic when that type is unsigned and we
return values less than zero to signal "already expired", used in
several places in the code.

Regression since f121575c

This avoids warnings about unused stuff.

"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.

Closes #2025

- 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.

Fixes timeouts in the fuzzing tests for non-FTP protocols.

Closes #2016

Allow users to specify their own hash define for
CURL_CONNECTION_HASH_SIZE so that both values can be overridden.

Closes #1982

... since the 'tv' stood for timeval and this function does not return a
timeval struct anymore.

Also, cleaned up the Curl_timediff*() functions to avoid typecasts and
clean up the descriptive comments.

Closes #2011

When using the FTP list parser, ensure that the memory that's
allocated is always freed.

Closes #2013

... to cater for systems with unsigned time_t variables.

- Renamed the functions to curlx_timediff and Curl_timediff_us.

- Added overflow protection for both of them in either direction for
  both 32 bit and 64 bit time_ts

- Reprefixed the curlx_time functions to use Curl_*

Even if OpenSSL is enabled, it might not be the default backend when
multi-ssl is enabled, causing the test to fail.

On OS/400, `close' is an ASCII system macro that corrupts the code if
not used in a context not targetting the close() system API.

Also adjust makefile to renamed files and warn about installation dirs mix-up.
