c2i_ASN1_BIT_STRING takes length as a long but uses it as an int. Check
bounds before doing so. Previously, excessively large inputs to the
function could write a single byte outside the target buffer. (This is
unreachable as asn1_ex_c2i already uses int for the length.)

return true for characters > 127. I.e. they are allowing extended ASCII
characters through which then cause problems. E.g. marking superscript '2' as
a number then causes the common (ch - '0') conversion to number to fail
miserably. Likewise letters with diacritical marks can also cause problems.
If a non-ASCII character set is being used (currently only EBCDIC), it is
adjusted for.
The implementation uses a single table with a bit for each of the defined
classes. These functions accept an int argument and fail for
values out of range or for characters outside of the ASCII set. They will
work for both signed and unsigned character inputs.

Trouble was that integer negation wasn't producing *formally* correct
result in platform-neutral sense. Formally correct thing to do is
-(int64_t)u, but this triggers undefined behaviour for one value that
would still be representable in ASN.1. The trigger was masked with
(int64_t)(0-u), but this is formally inappropriate for values other
than the problematic one. [Also reorder branches to favour most-likely
paths and harmonize asn1_string_set_int64 with asn1_get_int64].]

Clearing a misunderstanding. The routines c2i_uint64_int() and
i2c_uint64_int() expect to receive that internal values are absolute
and with a separate sign flag, and the x_int64.c code handles values
that aren't absolute and have the sign bit embedded. We therefore
need to convert between absolute and non-absolute values for the
encoding of negative values to be correct.

LONG and ZLONG items (which are OpenSSL private special cases of
ASN1_INTEGER) are encoded into DER with padding if the leading octet
has the high bit set, where the padding can be 0x00 (for positive
numbers) or 0xff (for negative ones).
When decoding DER to LONG or ZLONG, the padding wasn't taken in
account at all, which means that if the encoded size with padding
is one byte more than the size of long, decoding fails. This change
fixes that issue.
