Wolfgang Hotwagner cb70d85c69 conf: fix NULL-pointer dereference in CoredumpLoadConfig 
An empty value for coredump.max-dump in the config-file leads to a segfault because of a NULL-pointer dereference in CoredumpLoadConfig().

Here is a configuration example:

coredump.max-dump: []

This lets suricata crash with a segfault:

ASAN-output:

Victor Julien ab1200fbd7 compiler: more strict compiler warnings 
Set flags by default:

    -Wmissing-prototypes
    -Wmissing-declarations
    -Wstrict-prototypes
    -Wwrite-strings
    -Wcast-align
    -Wbad-function-cast
    -Wformat-security
    -Wno-format-nonliteral
    -Wmissing-format-attribute
    -funsigned-char

Fix minor compiler warnings for these new flags on gcc and clang.
