dshow_capture.h sets up various flags before including windows headers
this must occur before other headers (like os_support.h) include these
headers without the setup

This could be fixed differently but for now this fixes building on mingw

Keep the code as similar as possible across the codepaths to
ease spotting it for factorization.

Based on a patch from Michael Niedermayer <michaelni@gmx.at>.

The code currently set the information in at least 4 places, spare
some pointless loops.

Make the code in the loop a little uniform to make easier factorize
it out later.

This makes sure that the internal utf8 path names are handled
properly - the normal file handling functions assume path names
are in the native codepage, which isn't utf8.

This assumes that the tools outside of lavf don't use the mkdir
definition. (The tools don't do the same reading of command line
parameters as wchar either - they probably won't handle all possible
unicode file parameters properly, but at least work more predictably
if no utf8/wchar conversion is involved.)

This is moved further down in os_support.h, since windows.h shouldn't
be included before winsock2.h, while io.h needs to be included before
the manual defines for lseek functions.

On windows, rename(2) will fail if the target file exists. On
unix this trick is used to make sure that people reading the file
either will get the full previous file, or the full new version
of the file, but no intermediate version.
