2018-10-05checksrc: enable strict mode and warningsDaniel Gustafsson
Enable strict and warnings mode for checksrc to ensure we aren't missing anything due to bugs in the checking code. This uncovered a few things which are all fixed in this commit: * several variables were used uninitialized * several variables were not defined in the correct scope * the whitelist filehandle was read even if the file didn't exist * the enable_warn() call when a disable counter had expired was passing incorrect variables, but since the checkwarn() call is unlikely to hit (the counter is only decremented to zero on actual ignores) it didn't manifest a problem.

2018-10-03memory: ensure to check allocation resultsDaniel Gustafsson
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.

2018-10-01CMake: Improve config installationRuslan Baratov
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).

2018-09-20vtls: fix ssl version "or later" behavior change for many backendsJay Satiro
- Treat CURL_SSLVERSION_MAX_NONE the same as CURL_SSLVERSION_MAX_DEFAULT. Prior to this change NONE would mean use the minimum version also as the maximum. This is a follow-up to 6015cef which changed the behavior of setting the SSL version so that the requested version would only be the minimum and not the maximum. It appears it was (mostly) implemented in OpenSSL but not other backends. In other words CURL_SSLVERSION_TLSv1_0 used to mean use just TLS v1.0 and now it means use TLS v1.0 *or later*. - Fix CURL_SSLVERSION_MAX_DEFAULT for OpenSSL. Prior to this change CURL_SSLVERSION_MAX_DEFAULT with OpenSSL was erroneously treated as always TLS 1.3, and would cause an error if OpenSSL was built without TLS 1.3 support.

2018-09-19urlapi: add CURLU_GUESS_SCHEME and fix hostname acceptanceDaniel Stenberg
In order for this API to fully work for libcurl itself, it now offers a CURLU_GUESS_SCHEME flag that makes it "guess" scheme based on the host name prefix just like libcurl always did. If there's no known prefix, it will guess "http://". Separately, it relaxes the check of the host name so that IDN host names can be passed in as well. Both these changes are necessary for libcurl itself to use this API. Assisted-by: Daniel Gustafsson Closes #3018
