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.

Add missing ASN1_TIME functions
Do some cleanup of the ASN1_TIME code.
Add ASN1_TIME_normalize() to normalize ASN1_TIME structures.
Add ASN1_TIME_compare() to compare two ASN1_TIME structures.
Add ASN1_TIME_cmp_time_t() to compare an ASN1_TIME to time_t
(generic version of ASN1_UTCTIME_cmp_time_t()).

Based on discussion in PR #3566. Reduce duplicated code in original
asn1_utctime_to_tm and asn1_generalizedtime_to_tm, and introduce a new
internal function asn1_time_to_tm. This function also checks if the days
in the input time string is valid or not for the corresponding month.
Test cases are also added.

Avoid some strlen operations when the previous sprintf return value can be used.
Also fix the undefined behaviour `*(long *)x = y` when x isn't a long or character pointer.

ASN1_GENERALIZEDTIME and ASN1_UTCTIME may be specified using offsets,
even though that's not supported within certificates.
To convert the offset time back to GMT, the offsets are supposed to be
subtracted, not added. e.g. 1759-0500 == 2359+0100 == 2259Z.

sure they are available in opensslconf.h, by giving them names starting

I've checked fairly well that nothing breaks with this (apart from
external software that will adapt if they have used something like
NO_KRB5), but I can't guarantee it completely, so a review of this
change would be a good thing.

like Malloc, Realloc and especially Free conflict with already existing names

GeneralizedTime. At several points PKIX specifies that GeneralizedTime can be
used but OpenSSL doesn't currently support it. This patch adds several files
and a bunch of functions.
Of interest is the ASN1_TIME structure and its related functions. At several
points certificates, CRLs et al specify that a time can be expressed as a
choice of UTCTime and GeneralizedTime. Currently OpenSSL interprets this
(wrongly) as UTCTime because GeneralizedTime isn't supported. The ASN1_TIME
stuff provides this functionality.
Still todo is to trace which cert and CRL points need an ASN1_TIME and modify
the utilities appropriately and of course fix all the bugs.
Note new OpenSSL copyright in the new file a_time.c. I didn't put it in
a_gentm.c because it is a minimally modified form a_utctm.c .
Since this adds new files and error codes you will need to do a 'make errors'
at the top level to add the new codes.
