The basic API of rc-core used to be:
dev = rc_allocate_device();
dev->x = a;
dev->y = b;
dev->z = c;
rc_register_device();
which is a pretty common pattern in the kernel, after the introduction of
protocol arrays the API looks something like:
dev = rc_allocate_device();
dev->x = a;
rc_set_allowed_protocols(dev, RC_BIT_X);
dev->z = c;
rc_register_device();
There's no real need for the protocols to be an array, so change it
back to be consistent (and in preparation for the following patches).

Right now the protocol information is not preserved, rc-core gets handed a
scancode but has no idea which protocol it corresponds to.
This patch (which required reading through the source/keymap for all drivers,
not fun) makes the protocol information explicit which is important
documentation and makes it easier to e.g. support multiple protocols with one
decoder (think rc5 and rc-streamzap). The information isn't used yet so there
should be no functional changes.

The allowed and enabled protocol masks need to be expanded to be per
filter type in order to support wakeup filter protocol selection. To
ease that process abstract access to the rc_dev::allowed_protos and
rc_dev::enabled_protocols members with inline functions.

store_protocols() treats dev->rc_map.rc_type as a bitmap which is wrong for
two reasons. First of all, it is pretty bogus to change the protocol type of
the keymap just because the hardware has been asked to decode a different
protocol.
Second, dev->rc_map.rc_type is an enum (i.e. a single protocol) as pointed
out by James Hogan <james.hogan@imgtec.com>.
Fix both issues by introducing a separate enabled_protocols member to
struct rc_dev.

The RC_TYPE_* defines are currently used both where a single protocol is
expected and where a bitmap of protocols is expected.
Functions like rc_keydown() and functions which add/remove entries to the
keytable want a single protocol. Future userspace APIs would also
benefit from numeric protocols (rather than bitmap ones). Keytables are
smaller if they can use a small(ish) integer rather than a bitmap.
Other functions or struct members (e.g. allowed_protos,
enabled_protocols, etc) accept multiple protocols and need a bitmap.
Using different types reduces the risk of programmer error. Using a
protocol enum whereever possible also makes for a more future-proof
user-space API as we don't need to worry about a sufficient number of
bits being available (e.g. in structs used for ioctl() calls).
The use of both a number and a corresponding bit is dalso one in e.g.
the input subsystem as well (see all the references to set/clear bit when
changing keytables for example).
This patch separate the different usages in preparation for
upcoming patches.
Where a single protocol is expected, enum rc_type is used; where one or more
protocol(s) are expected, something like u64 is used.
The patch has been rewritten so that the format of the sysfs "protocols"
file is no longer altered (at the loss of some detail). The file itself
should probably be deprecated in the future though.
