Use an unsigned variable: as the signed operation behavior is undefined,
this change silents clang-tidy about it.

When failing to set the 1.3 cipher suite, the wrong string pointer would

Ensure to clear the session object in case the libssh2 initialization
fails.
It could be argued that the libssh2 error function should be called to
get a proper error message in this case. But since the only error path
in libssh2_knownhost_init() is memory a allocation failure it's safest
to avoid since the libssh2 error handling allocates memory.

Most headerfiles end with a /* <headerguard> */ comment, but it was
missing from some. The comment isn't the most important part of our
code documentation but consistency has an intrinsic value in itself.
This adds header guard comments to the files that were lacking it.

Curl_follow() no longer frees the string. Make sure it happens in the
caller function, like we normally handle allocations.

Closes#3149
For IP addresses in the subject alternative name field, the length
of the IP address (and hence the number of bytes to perform a
memcmp on) is incorrectly calculated to be zero. The code previously
subtracted q from name.end. where in a successful case q = name.end
and therefore addrlen equalled 0. The change modifies the code to
subtract name.beg from name.end to calculate the length correctly.
The issue only affects libcurl with GSKit SSL, not other SSL backends.
The issue is not a security issue as IP verification would always fail.

Now FILE transfers send headers to the header callback like HTTP and
other protocols. Also made curl_easy_getinfo(...CURLINFO_PROTOCOL...)
work for FILE in the callbacks.
Makes "curl -i file://.." and "curl -I file://.." work like before
again. Applied the bold header logic to them too.

In case a very small buffer was passed to the version function, it could
result in the buffer not being NULL-terminated since strncpy() doesn't
guarantee a terminator on an overflowed buffer. Rather than adding code
to terminate (and handle zero-sized buffers), move to using snprintf()
instead like all the other vtls backends.

If a !checksrc! disable command specified to ignore zero errors, it was
still added to the ignore block even though nothing was ignored. While
there were no blocks ignored that shouldn't be ignored, the processing
ended with with a warning:
<filename>:<line>:<col>: warning: Unused ignore: LONGLINE (UNUSEDIGNORE)
/* !checksrc! disable LONGLINE 0 */
^
Fix by instead treating a zero ignore as a a badcommand and throw a
warning for that one.

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.

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.

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).
