ea2f04bffe lavfi/vf_histogram: replace round by lrint 
lrint is at least as fast, uses a superior rounding mode, and avoids an
implicit cast.

7af14b3726 lavfi/vf_colorlevels: replace round by lrint 
lrint avoids an implicit cast, and is not slower on non-broken libm's. Thus this
represents a Pareto improvement.

cc37b31ad3 lavfi/vf_colorchannelmixer: replace round by lrint 
lrint is faster here on -ftree-vectorize with GCC. This is likely simply
an artifact of GCC's rather terrible auto-vectorizer, since as per the
instruction set manuals cvtsd2si and cvttsd2si (or their vector equivalents)
have identical cycle timings.

Anyway, regardless of above, lrint is superior to round accuracy wise.

Safety guaranteed as long int has at least 32 bits.

ce10f572c1 nutdec: reject negative value_len in read_sm_data 
If it is negative, it can cause the byte position to move backwards in
avio_skip, which in turn makes sm_size negative and thus size larger
than the size of the packet buffer, causing invalid writes in avio_read.

Also fix potential overflow of avio_tell(bc) + value_len.
