php_value[xxx] in php-fpm pool - first declaration wins

Description

The following code:

[www]
; ...
pm.start_servers = 5
pm.start_servers = 6

php_value[default_socket_timeout] = 61
php_value[default_socket_timeout] = 62

Resulted in this result:

pm.start_servers = 6
php_value[default_socket_timeout] = 61

But I expected this output instead:

pm.start_servers = 6
php_value[default_socket_timeout] = 62

Note, with php_value entries, the first declaration wins and with other directives, the last declared value wins. This behavior of php_value entries is inconsistent with the way the rest of the php configuration files operation.

This appears to function contrary to the php-fpm configuration documentation which reads:

PHP settings passed with php_value or php_flag will overwrite their previous value.

该 issue 未指定源文件或测试。首先在 PHP-FPM pool 配置中复现重复的 php_value 声明，并跟踪 php_value 与 pm.start_servers 的配置处理逻辑。完成的标准是：后出现的 php_value 声明始终按照文档所述的行为生效，并且为重复声明提供覆盖测试。
