msm: vidc: Add support to request frame level QP information

The resulting QP information for H264 is the slice level
QP averaged over whole frame; for all other codecs its
frame level QP.

msm: vidc: Add support to request frame bits info as extra-data

Provides information regarding number of bits in the frame (i.e frame
size expressed in bits) & also the number of bits in frame header (i.e
frame header size expressed in bits).
Number of bits in header is reported as:
For H264, sum of all slice headers bits for all the slices in the frame.
For all other codecs, number of bits in the frame header.

msm: vidc: add control to enable Hierarchical P num layers

This change will enable firmware to perform Hierarchical
video encoding for P frames. Hierarchical video encoding is
used to improve error resilience and temporal scalability.
The encoded frames are logically organized in to multiple
layers with frames in one layer referencing only frames
from lower layers. The lowest layer, i.e. base layer, is
the only exception.

msm: vidc: Query the core on VIDIOC_G_FMT

Previously we only queried the core for buffer requirements in
VIDIOC_REQBUFS, and relied on that information in _G_FMT.  However,
there's no expectation that the client calls _REQBUFS before _G_FMT,
which leads to stale information being returned as part of _G_FMT.

As such, always retreive fresh info from the core for either ioctl.

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.

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.

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.
