Martin Storsjö de9cd1b173 lavf: Handle the environment variable no_proxy more properly 
The handling of the environment variable no_proxy, present since
one of the initial commits (de6d9b6404), is inconsistent with
how many other applications and libraries interpret this
variable. Its bare presence does not indicate that the use of
proxies should be skipped, but it is some sort of pattern for
hosts that does not need using a proxy (e.g. for a local network).

As investigated by Rudolf Polzer, different libraries handle this
in different ways, some supporting IP address masks, some supporting
arbitrary globbing using *, some just checking that the pattern matches
the end of the hostname without regard for whether it actually is
the right domain or a domain that ends in the same string.

This simple logic should be pretty similar to the logic used by
lynx and curl.

Mans Rullgard 91ac403b13 lavf: fix arithmetic overflows in avformat_seek_file() 
The values compared here can be more than INT64_MAX apart.  Since the
difference is always positive, converting to uint64_t before subtracting
gives the correct result without overflows.

Janne Grunau 7709ce029a lavf: avoid integer overflow in ff_compute_frame_duration() 
Scaling the denominator instead of the numerator if it is too large
loses precision. Fixes an assert caused by a negative frame duration in
the fuzzed sample nasa-8s2.ts_s202310.
