Processing of WNM frames can results in a lookup of the current BSS
table. As such, the testing tool needs to initialize the BSS table to
avoid NULL pointer dereferences. This is not an issue that would show up
with real production uses with wpa_supplicant since wpa_bss_init() is
called there.

The commit that renamed the WNM BTM deallocation function forgot to
update the fuzz tester tool.

The function wpa_config_get_line() is used by the wpa_supplicant config
file parser to retrieve the next non-comment non-blank line. We'll need
the same kind of functionality to implement the file-based external
password backend, so as a preparatory step this commit extracts the
function into its own standalone file in the utils package.
No functional changes are expected from this commit.

This is a newer version of tests/wnm-fuzzer tool as the initial step in
creating a more uniform set of fuzzing tools that can be used with both
libFuzzer and afl-fuzz.
