-gzip: fix compression level bug. Closes 9131
-fix broken logic to get the gzip_level_config value from options -1 to
--9.
-
-This fixes an off-by-one bug that caused gzip -9 output bigger files
-than the other compression levels.
-
-It fixes so that compression level 1 to 3 are actually mapped to level 4
-as comments say.
-
-It also fixes that levels -4 to -9 is mapped to correct level and avoids
-out-of-bounds access.

-ntpd: respond only to client and symmetric active packets
-The busybox NTP implementation doesn't check the NTP mode of packets
-received on the server port and responds to any packet with the right
-size. This includes responses from another NTP server. An attacker can
-send a packet with a spoofed source address in order to create an
-infinite loop of responses between two busybox NTP servers. Adding
-more packets to the loop increases the traffic between the servers
-until one of them has a fully loaded CPU and/or network.
