nginx-0.3.39-RELEASE import
*) Feature: the "uninitialized_variable_warn" directive; the logging
level of the "uninitialized variable" message was lowered from
"alert" to "warn".
*) Feature: the "override_charset" directive.
*) Change: now if the unknown variable is used in the "echo" and "if
expr='$name'" SSI-commands, then the "unknown variable" message is
not logged.
*) Bugfix: the active connection counter increased on the exceeding of
the connection limit specified by the "worker_connections"
directive; the bug had appeared in 0.2.0.
*) Bugfix: the limit rate might not work on some condition; the bug had
appeared in 0.3.38.
