Consolidate to a single asn1_time_from_tm() function

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()).

Replace '0' .. '9' compares with isdigit()

=head1 DESCRIPTION
The function ASN1_TIME_set() sets the ASN1_TIME structure B<s> to the
time represented by the time_t value B<t>. If B<s> is NULL a new ASN1_TIME
structure is allocated and returned.
The ASN1_TIME_set(), ASN1_UTCTIME_set() and ASN1_GENERALIZEDTIME_set()
functions set the structure B<s> to the time represented by the time_t
value B<t>. If B<s> is NULL a new time structure is allocated and returned.
ASN1_TIME_adj() sets the ASN1_TIME structure B<s> to the time represented
The ASN1_TIME_adj(), ASN1_UTCTIME_adj() and ASN1_GENERALIZEDTIME_adj()
functions set the time structure B<s> to the time represented
by the time B<offset_day> and B<offset_sec> after the time_t value B<t>.
The values of B<offset_day> or B<offset_sec> can be negative to set a
time before B<t>. The B<offset_sec> value can also exceed the number of
seconds in a day. If B<s> is NULL a new ASN1_TIME structure is allocated
seconds in a day. If B<s> is NULL a new structure is allocated
and returned.
ASN1_TIME_set_string() sets ASN1_TIME structure B<s> to the time
represented by string B<str> which must be in appropriate ASN.1 time
format (for example YYMMDDHHMMSSZ or YYYYMMDDHHMMSSZ). If B<s> is NULL
this function performs a format check on B<str> only.
The ASN1_TIME_set_string(), ASN1_UTCTIME_set_string() and
ASN1_GENERALIZEDTIME_set_string() functions set the time structure B<s>
to the time represented by string B<str> which must be in appropriate ASN.1
time format (for example YYMMDDHHMMSSZ or YYYYMMDDHHMMSSZ). If B<s> is NULL
this function performs a format check on B<str> only. The string B<str>
is copied into B<s>.
ASN1_TIME_set_string_X509() sets ASN1_TIME structure B<s> to the time
represented by string B<str> which must be in appropriate time format
@ -45,13 +86,21 @@ YYYYMMDDHHMMSSZ (leap second is rejected), all other ASN.1 time format
are not allowed. If B<s> is NULL this function performs a format check
on B<str> only.
ASN1_TIME_check() checks the syntax of ASN1_TIME structure B<s>.
The ASN1_TIME_normalize() function converts an ASN1_GENERALIZEDTIME or
ASN1_UTCTIME into a time value that can be used in a certificate. It
should be used after the ASN1_TIME_set_string() functions and before
ASN1_TIME_print() functions to get consistent (i.e. GMT) results.
ASN1_TIME_print() prints out the time B<s> to BIO B<b> in human readable

ASN1_TIME_adj() may change the type from ASN1_GENERALIZEDTIME to ASN1_UTCTIME,

ASN1_UTCTIME_adj() functions will not modify the type of the return structure.
It is recommended that functions starting with ASN1_TIME be used instead of
those starting with ASN1_UTCTIME or ASN1_GENERALIZEDTIME. The functions
starting with ASN1_UTCTIME and ASN1_GENERALIZEDTIME act only on that specific
time format. The functions starting with ASN1_TIME will operate on either
format.

out "GMT" or nothing. But all certificates complying with RFC5280 et al use GMT
