44782fd8af lib: change controlling expressions in if/while to Boolean
Use `do { ... } while (false)' instead of `do { ... } while (0)'.
Use comparisons with zero instead of implicitly testing integers.
Use comparisons with NULL instead of implicitly testing pointers.
Use comparisons with NUL instead of implicitly testing plain chars.
Use `bool' instead of `int' to represent Boolean values.
Use `while (true)' instead of `while (1)' to express infinite loops.

0e43b8861b libc: fix armclang compiler warnings with is*() functions
We get compile warnings of the form:

error: converting the result of
'<<' to a boolean; did you mean
'((__aeabi_ctype_table_ + 1)[(byte)] << 28) != 0'?
 [-Werror,-Wint-in-bool-context]
                if (!isprint(byte)) {
                     ^

Since isprint (and the other is* functions) return an int, change check
to an explicit test against the return value.

8521b43546 coding guidelines: comply with MISRA C:2012 Rule 21.13
MISRA C:2012 Rule 21.13 (Any value passed to a function in <ctype.h>
shall be representable as an unsigned char or be the value EOF).

Functions in <ctype.h> have undefined behavior if they are called with
any other value. Callers affected by this change are not prepared to
handle EOF anyway. The addition of these casts avoids the issue
and does not result in any performance penalty.

4c32258606 style: add braces around if/while statements
Per guidelines, all statements should have braces around them. We do not
have a CI check for this, so a few went in unnoticed.

4218d5f8f0 kernel: Make If statement have essentially Boolean type
Make if statement using pointers explicitly check whether the value is
NULL or not.

The C standard does not say that the null pointer is the same as the
pointer to memory address 0 and because of this is a good practice
always compare with the macro NULL.
