Replace strcpy, strncpy & co with strlcpy family functions

[xezon]

For robustness.

Depending on the complexity, better split individual kinds of functions into individual commits

• strcpy fix: Replace strcpy with strlcpy for robustness #1712
• strncpy fix: Replace strncpy with strlcpy for robustness #1533
• wcscpy - none present
• wcsncpy fix: Replace wcsncpy with wcslcpy for robustness #1676
• strcat fix: Replace strcat with strlcat for robustness #1685
• strncat fix: Replace strncat with strlcat for robustness #1677
• wcscat fix: Replace wcscat with wcslcat for robustness #1678
• wcsncat - none present
• sprintf
• swprintf
• Replace constants, defines and sizeof with ARRAY_SIZE

Probably even better to do a PR per function. Otherwise too many files get changed and reviewing in github gets harder.
