Title: Support changing default logger's max level before grn_init()

grn_init() logs some messages such as vm.overcommit_memory related
messages. vm.overcommit_memory related messages uses INFO log level.
The messages never be logged because the default max log level is
NOTICE and the default max log level can't be changed before grn_init().
