utstring.h: fix wrong sequence of parameters calling calloc().

[silvioprog]

Hello.

According to man 3 calloc, the first parameter of calloc() function is the nmemb of elements:

SYNOPSIS

...

       void *calloc(size_t nmemb, size_t size);

...

DESCRIPTION

...

       The  calloc()  function allocates memory for an array of nmemb elements
       of size bytes each and returns a pointer to the allocated memory.   The
       memory  is  set  to zero.  If nmemb or size is 0, then calloc() returns
       either NULL, or a unique pointer value that can later  be  successfully
       passed to free().

So this PR should fix it.

(notice it was property used here).

Thank you!

LGTM.

LGTM, but I'd be inclined to merge 1dd1d23 instead, because I don't see why we need calloc at all. Anyone feel like defending calloc here?
Otherwise I'll merge 1dd1d23 in a few days.

Issue #94 is tangentially related, btw.

Since utstring_init() already zero-initializes the structure, +1 for pure malloc() since . 😃

Closing to merge 1dd1d23 as better fixing.

Thanks dudes! 👍 😃 👍
