movenc: Check for errors from mov_create_chapter_track

On failures in the write_trailer function, we could also ignore
the errors and try to finish the file despite these errors (which
would only leave an incomplete chapters track). It's probably better
to signal the error clearly to the caller though (and if this
function failed there's no guarantee that there's enough memory to
finish the trailer either).

matroskaenc: Fix writing TRACKDEFAULTFLAG

The element was only being written when the value == 1.  But the default
value of this element is 1, so this has no useful effect.  This element
needs to be written when the value == 0.

smoothstreamingenc: Write to a temp file while updating the manifest

If a client tries to read the file while it's being updated, the client
would get an incomplete manifest. Instead write to a separate temp file
and atomically rename it to replace the previous one.

w32threads: Don't use function pointers when linking directly to newer APIs

This reduces the call overhead slightly. More noticeably, it
restores the earlier (unintended?) feature that condition variable
functions work just fine even if w32thread_init() hasn't been called.
This was broken as a side effect of 4622f11f9, if explicitly targeting
Vista+.

This makes w32threading work in VP8 again, if targeting Vista+.

Revert "w32pthread: help compiler figure out undeeded code"

This reverts commit 4622f11f9c83db8a2e08408c71ff901826ca652c.

The compiler should be able to do the dead code elimination now
without this when the cond_* names point directly to the real
functions instead of to local function pointers.
