Ezequiel Garcia b9b1b3a8f7 [media] dvb-core: Replace memcpy with struct assignment
This kind of memcpy() is error-prone. Its replacement with a struct
assignment is prefered because it's type-safe and much easier to read.
Found by coccinelle. Hand patched and reviewed.
Tested by compilation only.
A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)
// <smpl>
@@
identifier struct_name;
struct struct_name to;
struct struct_name from;
expression E;
@@
-memcpy(&(to), &(from), E);
+to = from;
// </smpl>

Juergen Lock 6ae2322455 [media] dvb_frontend: fix ioctls failing if frontend open/closed too fast
That likely fixes this MythTV ticket:
	http://code.mythtv.org/trac/ticket/10830
(which btw affects all usb tuners I tested as well, pctv452e,
dib0700, af9015)  pctv452e is still possibly broken with MythTV
even after this fix; it does work with VDR here tho despite I2C
errors.
Reduced testcase:

Thanx to devinheitmueller and crope from #linuxtv for helping with
this fix! :)

Antti Palosaari 33eebec55c [media] dvb: LNA implementation changes
* use dvb property cache
* implement get (thus API minor++)
* PCTV 290e: 1=LNA ON, all the other values LNA OFF
  Also fix PCTV 290e LNA comment, it is disabled by default
Hans and Mauro proposed use of cache implementation of get as they
were planning to extend LNA usage for analog side too.

Evgeny Plehov 287cefd096 [media] dvb_frontend: add multistream support
Unify multistream support at the DVBAPI: several delivery systems
allow it. Yet, each one had its own name. So, instead of adding
a third version of this field, remove the per-standard naming,
unifying it into a common name.

The legacy code number can still be used by old applications.

Version increased to 5.8.
