The new name is more meaningful/less confusing.

Consistent with segment_start() and less confusing.

The filter contexts are completely cleared,
so the frame size can not be kept.

Possibly improve readability.

This allows passing the right options to encoders when there's more
than one encoder for a certain codec id.

Mingw headers provide similar defines already (unconditional #defines,
without any #undef or #ifdef around it), while MSVC doesn't have
them.

The fallback function is a non-static function, we shouldn't be
defining non-static functions outside of the proper ff/av prefix
namespaces.

This is especially important for a function like poll, which
other parties (other libraries, or executables linking these
libraries) also might provide similar but incompatible fallbacks for.

We need to include winsock2.h here, to make sure we have the
real pollfd struct definition, if one exists, before defining the
fallback poll function.

The fds are unsigned integers in the windows definition of struct
sockfds. Due to this, the comparison if (fds[i].fd > n) was always
false.

io.h is required for open and _wopen, and fcntl.h is required for
the O_CREAT flag. On mingw, fcntl.h is included by os_support.h (and
the mingw fcntl.h includes io.h), but include it explicitly here
since this implementation requires it.

Also move the #undef open up. open must not be defined to ff_win32_open
while including the headers that declare the open function. On mingw,
this happened in os_support.h before open was redirected.

Links can be set up to group samples into buffers of
specified minimum and maximum size.

It broke twice in the last three months due to other changes.

Identical to commit 4f6a1c97 by Reimar Döffinger,
that was lost after the merge of 19ad5673.
