Secure String Copy in eos_parse

[ericpassmore]

src/eos_parse.c:210:5: warning: Call to function 'strcat' is insecure as it does not provide bounding of the memory buffer. Replace unbounded copy functions with analogous functions that support length arguments such as 'strlcat'. CWE-119 [security.insecureAPI.strcpy] strcat(arg->data, "@"); ^~

[ericpassmore]

from strcat(arg->data, "@"); to strlcat(arg->data, "@", 1);

[ericpassmore]

actionArgument_t.data is char[128].

[greg7mdp]

see https://linux.die.net/man/3/strlcpy, last argument should be the full size of the buffer, so sizeof(arg->data) in this case.
