4e23ee03ca Handle failed system calls 
Introduce a separate TU for utility functions util.c. Add a function
exec_cmd to simplify execution of system commands with error handling.

While at it, suppress a warning about unused result when executing a
shell command. As we only display the command's output we do not care
about the exit code.

This fixes Debian bug #398989[0]

89e60cc474 form.c: do not gratuitously turn GET into POST 
When encountering a <form ...> tag that contains these values:

    method="get" enctype="multipart/form-data"

Do not transform the method into POST to accomodate enctype.

Instead behave in the compatible way that all other browsers
behave in this instance and ignore the enctype parameter
(treating it as the default application/x-www-form-urlencoded)
and perform a "GET" just as the method parameter requests.

This behavior produces far more compatible results than
gratuitously changing the "get" into a "post" which can
result in unexpected "405 Method Not Allowed" errors.
