A few changes in tests about number of bits in integers
...
- The preprocessor must work with at least 'long', and therefore must
do shifts of up to 31 bits correctly.
- Whenever possible, use unsigned types in shifts.

Name 'nonstrict' in the UTF-8 library changed to 'lax'
...
It is not a good idea to use negative words to describe boolean
values. (When we negate that boolean we create a double negative...)

Changes in the validation of UTF-8
...
All UTF-8 encoding functionality (including the escape
sequence '\u') accepts all values from the original UTF-8
specification (with sequences of up to six bytes).
By default, the decoding functions in the UTF-8 library do not
accept invalid Unicode code points, such as surrogates. A new
parameter 'nonstrict' makes them accept all code points up to
(2^31)-1, as in the original UTF-8 specification.

Avoid using 'int' for UTF-8 values
...
An 'int' may have only 16 bits, so it may not be big enough for UTF-8
values. The new type 'utfint' (in the utf8 library) ensures at least
21 bits for those values.

...
that the function cannot continue past that call)
