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.

qt-faststart is terribly slow when the input file and the output file
are on a slow disk like a SD card. By increasing the copy_buffer from
1K to 32M I decreased the processing time on a sample file from
1600 seconds to 4 seconds. The timing difference is during 'copying
rest of file'.
