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.

This extends the INDENTATION case to also handle 'else' statements
and require proper indentation on the following line. Also fixes the
offending cases found in the codebase.

... but output non-stripped version of the line, even if that then can
make the script identify the wrong position in the line at
times. Showing the line stripped (ie without comments) is just too
surprising.

This check scans for fopen() with a mode string without 'b' present, as
it may indicate that an FOPEN_* define should rather be used.
The list of unsafe functions currently consists of sprintf, vsprintf,
strcat, strncat and gets.
Subsequently, some existing code needed updating to avoid warnings on
this.
Allow configure builds to generate src/config-win32.h
Skip checksrc on src/config-win32.h contents already checked at lib/config-win32.h
Allow multiple -W in checksrc.pl
It now scans multiple files and outputs an error+warning count summary
at the end in case at least one was detected.
-D can be used to specify in which dir the files are located
The script now scans for conditions that starts with a space for
if/while/for lines.
