a2fcab9978 Fix undefined behaviour in shifts.
Td4 and Te4 are arrays of u8. A u8 << int promotes the u8 to an int first then shifts.
If the mathematical result of a shift (as modelled by lhs * 2^{rhs}) is not representable
in an integer, behaviour is undefined. In other words, you can't shift into the sign bit
of a signed integer. Fix this by casting to u32 whenever we're shifting left by 24.

(For consistency, cast other shifts, too.)

e6dcb08984 ASN1_primitive_new NULL param handling
ASN1_primitive_new takes an ASN1_ITEM * param |it|. There are a couple
of conditional code paths that check whether |it| is NULL or not - but
later |it| is deref'd unconditionally. If |it| was ever really NULL then
this would seg fault. In practice ASN1_primitive_new is marked as an
internal function in the public header file. The only places it is ever
used internally always pass a non NULL parameter for |it|. Therefore, change
the code to sanity check that |it| is not NULL, and remove the conditional
checking.

e961fa4479 Restore -DTERMIO/-DTERMIOS on Windows platforms.
The previous defaulting to TERMIOS took away -DTERMIOS / -DTERMIO a
bit too enthusiastically.  Windows/DOSish platforms of all sorts get
identified as OPENSSL_SYS_MSDOS, and they get a different treatment
altogether UNLESS -DTERMIO or -DTERMIOS is explicitely given with the
configuration.  The answer is to restore those macro definitions for
the affected configuration targets.

aafdbbc469 Assume TERMIOS is default, remove TERMIO on all Linux.
The rationale for this move is that TERMIOS is default, supported by
POSIX-1.2001, and most definitely on Linux.  For a few other systems,
TERMIO may still be the termnial interface of preference, so we keep
-DTERMIO on those in Configure.

crypto/ui/ui_openssl.c is simplified in this regard, and will define
TERMIOS for all systems except a select few exceptions.
