vsnprintf() replacement using a big malloc()ed internal buffer, originally by David Pfitzner dwp@m.nosp@m.so.a.nosp@m.nu.ed.nosp@m.u.au
Parameter n specifies the maximum number of characters to produce. This includes the trailing null, so n should be the actual number of characters allocated (or sizeof for char array). If truncation occurs, the result will still be null-terminated. (I'm not sure whether all native vsnprintf() functions null-terminate on truncation; this does so even if calls native function.)
Return value: if there is no truncation, returns the number of characters printed, not including the trailing null. If truncation does occur, returns the number of characters which would have been produced without truncation. (Linux man page says returns -1 on truncation, but glibc seems to do as above nevertheless; configure tests this.)
[glibc is correct. Viz.
PRINTF(3) Linux Programmer's Manual PRINTF(3)
(Thus until glibc 2.0.6. Since glibc 2.1 these functions follow the C99 standard and return the number of characters (excluding the trailing '\0') which would have been written to the final string if enough space had been available.)]
The method is simply to malloc (first time called) a big internal buffer, longer than any result is likely to be (for non-malicious usage), then vsprintf to that buffer, and copy the appropriate number of characters to the destination. Thus, this is not 100% safe. But somewhat safe, and at least safer than using raw snprintf! :-) (And of course if you have the native version it is safe.)
Before rushing to provide a 100% safe replacement version, consider the following advantages of this method:

cat_snprintf() is like a combination of fc_snprintf() and fc_strlcat(); it does snprintf() to the end of an existing string.
Like fc_strlcat(), n is the total length available for str, including existing contents and trailing nul. If there is no extra room available in str, does not change the string.
Also like fc_strlcat(), returns the final length that str would have had without truncation, or -1 if the end of the buffer is reached. I.e., if return is >= n, truncation occurred.

| size_t fc_strlcpy | ( | char * | dest, |

fc_strlcpy() provides utf-8 version of (non-standard) function strlcpy() It is intended as more user-friendly version of strncpy(), in particular easier to use safely and correctly, and ensuring nul-terminated results while being able to detect truncation.
n is the full size of the destination buffer, including space for trailing nul, and including the pre-existing string for fc_strlcat(). Thus can eg use sizeof(buffer), or exact size malloc-ed.
Result is always nul-terminated, whether or not truncation occurs, and the return value is the strlen the destination would have had without truncation. I.e., a return value >= input n indicates truncation occurred.
Not sure about the asserts below, but they are easier than trying to ensure correct behaviour on strange inputs. In particular note that n == 0 is prohibited (e.g., since there must at least be room for a nul); could consider other options.
