Fixes #2929
Closes #3080

The result of a memory allocation should always be checked, as we may
run under memory pressure where even a small allocation can fail. This
adds checking and error handling to a few cases where the allocation
wasn't checked for success. In the ftp case, the freeing of the path
variable is moved ahead of the allocation since there is little point
in keeping it around across the strdup, and the separation makes for
more readable code. In nwlib, the lock is aslo freed in the error path.

Also bumps the copyright years on affected files.

Bug: #3077

runtests.pl support running a range of tests, like "44 to 127". Starting
now, the code makes sure that even such given ranges will ignore tests
that are marked as disabled.

Disabled tests can still be run by explictly specifying that test
number.

CURLOPT_POSTFIELDSIZE is long. Fixes a compiler warning on 64-bit
MinGW.

Use 'GNUInstallDirs' standard module to set destinations of installed
files.

Use uppercase "CURL" names instead of lowercase "curl" to match standard
'FindCURL.cmake' CMake module:
* https://cmake.org/cmake/help/latest/module/FindCURL.html

Meaning:
* Install 'CURLConfig.cmake' instead of 'curl-config.cmake'
* User should call 'find_package(CURL)' instead of 'find_package(curl)'

Use 'configure_package_config_file' function to generate
'CURLConfig.cmake' file. This will make 'curl-config.cmake.in' template
file smaller and handle components better.  E.g.  current configuration
report no error if user specified unknown components (note: new
configuration expects no components, report error if user will try to
specify any).

Due to an issue with travis

Closes #3057

Changes in commit 7867aaa9 (cmake: link curl to the OpenSSL targets
instead of lib absolute paths, 2018-07-17) and commit f826b4ce (cmake:
bumped minimum version to 3.4, 2018-07-19) required CMake 3.4 to fix
issue #2746.  This broke support for users on older versions of CMake
even if they just want to build curl and do not care whether transitive
dependencies work.

Backport the logic to work with CMake 3.0 again by implementing the
fix only when the version of CMake is at least 3.4.

Classic MinGW still has _beginthreadex's return type as unsigned long
