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.
