Some firewalls mandate a minimum size of 4k for SYN packets, which
transmission does not do by default. Upstream issue here:

Cleanup:

Fixed license info.

Removed two unnecessary patches.

The init script runs transmission with the foreground parameter for procd to control it. However, if transmission is ran in the foreground, nothing is logged to syslog. Added a patch to remove this restriction.

Also added a sysctl file that removes these warnings:

UDP Failed to set receive buffer: requested 4194304, got 262142 (tr-udp.c:75)
UDP Please add the line "net.core.rmem_max = 4194304" to /etc/sysctl.conf (tr-udp.c:80)
UDP Failed to set send buffer: requested 1048576, got 262142 (tr-udp.c:86)
UDP Please add the line "net.core.wmem_max = 1048576" to /etc/sysctl.conf (tr-udp.c:91)
