sfeed.c: parsetime improve parsing RFC2822 obsolete short year
https://datatracker.ietf.org/doc/html/rfc2822#section-4.3
"Where a two or three digit year occurs in a date, the year is to be
interpreted as follows: If a two digit year is encountered whose
value is between 00 and 49, the year is interpreted by adding 2000,
ending up with a value between 2000 and 2049. If a two digit year is
encountered with a value between 50 and 99, or any three digit year
is encountered, the year is interpreted by adding 1900."
Improvement on commit 7086670e4335714e1df982bf1058082b7400b653
For example (output from TZ=UTC sfeed_plain):
input: Sun, 26 Jul 049 19:26:34
was: 2049-07-26 19:26
now: 1949-07-26 19:26 (because this is a 3-digit year)
input: Sun, 26 Jul 1 19:26:34
was: 2001-07-26 19:26
now: 0001-07-26 19:26 (because this is a 1-digit year and doesn't match the short year rule)
input: Sun, 26 Jul 001 19:26:34
was: 2001-07-26 19:26
now: 1901-07-26 19:26 (because this is a 3 digit year)
These cases are all added to the tests in the sfeed_tests repo (times.xml file).
