Localization: Make Qt's locale-aware formatting accessible from C
This commit introduces functions:
- QString asprintf_loc(const char *cformat, ...);
- int snprintf_loc(char *dst, size_t size, const char *cformat, ...);
- put_format_loc(struct membuffer *, const char *fmt, ...);
and their va_arg equivalents, which use Qt's QString::arg() formatting
options to render the strings.
The snprintf_loc() function takes care not to truncate multi-byte
UTF-8 encodings. Thus, on overflow, the resulting string might be
shorter than size-1.
