net: core: Support UID-based routing.

This contains the following commits:

1. 0149763 net: core: Add a UID range to fib rules.
2. 1650474 net: core: Use the socket UID in routing lookups.
3. 0b16771 net: ipv4: Add the UID to the route cache.
4. ee058f1 net: core: Add a RTA_UID attribute to routes.
    This is so that userspace can do per-UID route lookups.

msm: vidc: Amend calculation of buffer sizes in VENUS_BUFFER_SIZE

Add 8KB worth of padding for extradata. This is required to accommodate
some of the larger extradata types that didn't fit into the residual
space between the actual buffer size and its aligned size.

msm: vidc: Expose extradata size to userspace

Previously, the extradata size was included within VENUS_BUFFER_SIZE
and callers (primarily in userspace) wouldn't know how much extra
padding was added to the buffer size. Exposing it allows userspace to
query directly instead of doing guesswork.

for the metadata information.

msm: vidc: Change in input buffer size calculation

Right now, input buffer size is calculated based on
maximum supported height and width returned from FW.
These values are not true representation as they are
calculated for rotation usecase. Driver needs to use
max MB supported from FW. This change fixes the same.

msm: mdss: Enable fixed MMBs support for RGB pipes

RGB pipes in some of the chip-sets are statically tied to dedicated
Memory Macro Blocks (MMBs) out of common shared memory pool. These MMBs
cannot be used by other pipes. Enable support for this fixed MMBs by
parsing indexes from device tree and reserving fixed MMBs first before
general pool is used.

msm: mdss: Allow smp change during composition switch

The composition fallback mechanism might not ensure unsetting of
the pipe whose prepare call failed due to smp configuration change,
typically in the cases where change in composition requests same
pipe. This scenario is a deadlock where composition switch does
not happen, due to these pipe failures.

To handle such cases, for changed SMP request for a pipe doing
non backend composition, allow smp configuration to happen, so
that the composition could be successfully switched, thereby
preventing the deadlock.

mdss: Add MDP_SMP_FORCE_ALLOC mdp flag

MDP_SMP_FORCE_ALLOC flag is used to allow SMP
allocations even when there is mismatch between
allocated and requested SMPs for a pipe.
User space can make use of this flag in extreme scenarios
where SMP allocations need to pass like GPU composition
and playback of protected  or secure videos.

nl80211: vendor command support

Add support for vendor-specific commands to nl80211. This is
intended to be used for really vendor-specific functionality
that can't be implemented in a generic fashion for any reason.
It's *NOT* intended to be used for any normal/generic feature
or any optimisations that could be implemented across drivers.
Currently, only vendor commands (with replies) are supported,
no dump operations or vendor-specific notifications.
Also add a function wdev_to_ieee80211_vif() to mac80211 which
is needed for mac80211-based drivers wanting to implement any
vendor commands.

nl80211: support vendor-specific events

In addition to vendor-specific commands, also support vendor-specific
events. These must be registered with cfg80211 before they can be used.
They're also advertised in nl80211 in the wiphy information so that
userspace knows can be expected. The events themselves are sent on a
new multicast group called "vendor".
