Log:
  multimedia/tvheadend: fix two major problems of webui on FreeBSD
  
  1. very high CPU usage while streaming a recored program
  2. unable to stream the recorded program beyond 128MB.
  
  Unlike Linux sendfile(), FreeBSD sendfile() requires an explicit
  file offset, and return value must be checked to catch any error
  occurred. (i.e., closed connection)

+Subject: [PATCH] webui: fix http_serve_file() for FreeBSD
+
+This patch fixes two major problems of FreeBSD port of tvheadend:
+
+1. very high CPU usage while streaming a recored program
+2. unable to stream the recorded program beyond 128MB.
+
+Unlike Linux sendfile(), FreeBSD sendfile() requires an explicit
+file offset, and return value must be checked to catch any error
+occurred. (i.e., closed connection)
+
+Patch tested with the latest FreeBSD port of tvheadend-4.2.6.
