This structure is used in the interface between libs and thus cannot have

Without this cast, the BE_32() expression is sign extended when
assigned to an uint64_t, since the uint8_t|uint8_t expression
is promoted to an int.
Also avoid undefined behaviour when left shifting an uint8_t
by 24 by casting it to an uint32_t explicitly before shifting.
Based on a patch by Michael Niedermayer.

These variables are assigned the return values of ftello, which
returns an off_t, which is a signed type. On errors, ftello returns
-1, thus make sure this error return value can be stored properly.

qt-faststart doesn't use the normal libav headers at all since
it's supposed to be a completely standalone tool, so we implement
the macro locally in this file.

Copying data in chunks of 1 KB is a little wasteful.
64 KB should still easily fit on the stack, so there's no need
to allocate it dynamically.

avcodec_flush_buffers() must release all internally held references
according to its documentation, for which all the threads need to be
flushed.

A threading type might be detected originally, but later disabled
if one of its dependencies is unavailable.
This makes sure that the threading support item in the configure
output is right for setups where w32threads are available but
native atomics aren't.
