The so-called "Vista/7 helpers" only define interfaces missing from mingw*

Remove duplicate declarations already in all mingw headers, include the
correct headers instead.

Link video outputs against libuuid to get the existing UUID instead of
defining our own.

Define the C interfaces as Microsoft does it by using lpVtbl for the
virtual table pointer.
See http://blogs.msdn.com/b/oldnewthing/archive/2004/02/05/68017.aspx

Define a C++ interface to TaskbarList3 for qt4, keep the C for video outputs.
Define only a C++ interface to IApplicationAssociationRegistrationUI

Define TaskbarList3->SetTabActive() correctly.
See http://msdn.microsoft.com/en-us/library/windows/desktop/dd391699(v=vs.85).aspx

ifdef the TaskbarList3 interface because mingw-w64 defines it already.

We can only use it at application level
Just use the default libav* callback instead which prints to stderr
We might want to set libav* verbosity with av_log_set_level()

We don't need to handle OSX shared libraries anymore
It now runs much faster

detect errors and abort writing if they happen

In process-level mode we would call the context-level callback

Disable the OSS support on OpenBSD by default.

This fixes up the *BSD handling within the Operating System check.
SYS is now set to the OS without the version attached as provided
by ${host_os} (.e.g. openbsd instead of openbsd5.1) to match all
the other OS's and simplifies other OS's checks further down. This
also allows the script to recognize DragonFly.

This fixes the libpng check on OpenBSD. Although the code was passing libm to
ultimately link the library the test itself was not and thus failing. Also at
Remi's request I changed the existing and newly introduced use of -lm to $LIBM.

Define it to EFBIG (file too big), it's close enough in this specific use

- fix bug in ACCESS_GET_PTS_DELAY where it would fall through the next case
- print error messages from libavformat
- remove useless strdup
- check for exclusive access to avio when context open succeeded
- support for multiple input / output at the same time with libavformat > 54 (untested)

ffmpeg/libav doc/APIchanges should not be relied upon

It seems really unusable on win32

macosx: implements user choice to autosave volume on exit and changes volume slider range to 0 ... 200%

this adds the configuration variable and also the respective gui modifications for
simple prefs dialog. Also, this commit changes some spacing in gui to be consistent
between the different tabs.
