strncpy(3) is not so safe function and can lead to mistakes. For
example, strncpy(dest, "Profanity", 10); is redundant and leads to
problems when someone changes the source string.
Different example is when 3rd argument equals to length of the
destination buffer. strncpy(3) doesn't terminate string with '\0' when
it truncates. Therefore, the destination string becomes corrupted.
Zeroize storage for 'nid', so the last byte remains '\0' in case of
truncate.
Since d92c576aa5
we rely on g_spawn_sync().
Which doesn't do variable/glob expansion.
For our use of call_external() in opening and URL or avatar this is
fine.
For getting the password we want to be able to use ~ for our files.
Let's use a shell here.
Fix https://github.com/profanity-im/profanity/issues/1364
With recent changes to c99 and -D_POSIX_C_SOURCE=200809L we get the following:

Let us use gnu99. Has been proposed before already and is fine.

sets C99 as standard.
strdup() is not part of C99.
For now set `-D_POSIX_C_SOURCE=200809L` macro to have strdup() in C99.
Using `gnu99` instead would be another option.
We should take more care to use glib functions whenever possible.

Not sure if it is related.
man 3 getenv sais:
```
As typically implemented, getenv() returns a pointer to a string within
the environment list. The caller must take care not to modify this
string, since that would change the environment of the process.
```
Some systems don't provide recent libstrophe releases. When older
version of libstrophe is detected, don't build legacy auth support.
To simplify this patch, report about unsupported legacy auth and
keep commands option as is.
