[PATCH 00/12] Fix Unchecked return value from library errors

[Ryan Long]

Hi,

Here are the fixes for the "Unchecked return value from library"
Coverity errors. For most of these, I added a status code variable,
returned the value, and used the _Assert_Unused_variable_equal/unequal
macros. For main_help.c, a (void) was just added because we don't care
about the value that is returned.
