Merge of r4617: fastcgi padding fix.
Fastcgi: fixed padding handling on fixed-size records.
Padding was incorrectly ignored on end request, empty stdout and stderr
fastcgi records. This resulted in protocol desynchronization if fastcgi
application used these records with padding for some reason.
Reported by Ilia Vinokurov.

17 * Linux does not test /etc/localtime change in localtime(), | |
