Remove superfluous null-checks before strdup/free
NULL checks were removed for following free functions:
- g_free "If mem is NULL it simply returns"
https://developer.gnome.org/glib/stable/glib-Memory-Allocation.html#g-free
- g_slist_free(_full)? "NULL is considered to be the empty list"
https://developer.gnome.org/glib/stable/glib-Singly-Linked-Lists.html
- g_strfreev "If str_array is NULL, this function simply returns."
https://developer.gnome.org/glib/stable/glib-String-Utility-Functions.html#g-strfreev
- g_slice_free "If mem is NULL, this macro does nothing."
https://developer.gnome.org/glib/stable/glib-Memory-Slices.html#g-slice-free
- g_match_info_free "not NULL... otherwise does nothing"
https://developer.gnome.org/glib/stable/glib-Perl-compatible-regular-expressions.html#g-match-info-free
- dfilter_free defined in Wireshark code. Returns early when passed NULL
epan/dfilter/dfilter.c
They were also removed around calls to g_strdup where applicable:
- g_strdup "If str is NULL it returns NULL."
https://developer.gnome.org/glib/stable/glib-String-Utility-Functions.html#g-strdup
