Unicode replace() avoids calling unicode_adjust_maxchar() when it's useless

If maxchar == PyUnicode_MAX_CHAR_VALUE(unicode), we do an useless copy.

Add asciilib: similar to ucs1, ucs2 and ucs4 library, but specialized to ASCII
...
ucs1, ucs2 and ucs4 libraries have to scan created substring to find the
maximum character, whereas it is not need to ASCII strings. Because ASCII
strings are common, it is useful to optimize ASCII.

shorter character type. For example, _PyUnicode_FromUCS1() stops if we
have at least one character in range U+0080-U+00FF
