Shuhei Matsumoto 8adbd90991 util/string: sprintf_append_realloc to concatenate strings with realloc
Appending string by using sprintf with realloc will be generally
usable and add sprintf_append_realloc() and vsprintf_append_realloc()
to the utility.

These APIs follow realloc about buffer management, i.e., the original
buffer is left untouched if they fail.

Besides, the original buffer is NULL, they are equivalent to
sprintf_alloc() and vsprintf_alloc(), respectively.
