BUG/MINOR: server: Make SRV_STATE_LINE_MAXLEN value from 512 to 2kB (2000 bytes).

The statefile before this patch can only parse lines within 512
characters, now as we made the value to 2000, it can support a
line of length of 2kB.

This patch fixes GitHub issue #1530.
It should be backported to all stable releases.
