Allow the configure tool to call the gas-preprocessor with an absolute
path when included with either the "--as" or with a separate "--gas"
option.  The patch is backward compatible and will not break any current
configuration setups.

The new behavior that comes with this option can be utilized in the
following ways:

Examples:

- Just as single option that includes both the gas-preprocessor.pl and
  cc/as at the same time:

  $ configure --as="/opt/app/build-tools/gas-preprocessor.pl \
                   /Applications/Xcode.app/.../Developer/usr/bin/gcc"

- Call gas-preprocessor with a separate option in conjunction with --as:

  $ configure --gas="/opt/app/build-tools/gas-preprocessor.pl" \
               --as="/Applications/Xcode.app/.../Developer/usr/bin/gcc"

- Address only the the gas-preprocessor and it will automatically fall
  back to as or cc whichever that's defined:
  $ configure --gas="/opt/app/build-tools/gas-preprocessor.pl"

- Or if no gas-preprocessor.pl is explicitly defined, it falls back to
  the old behaivor.

This fixes rounding differences between platforms

After this commit applications needs to call av_format_inject_global_side_data()
or handle AVStream side data by some other means if they want it not to be lost.

This fixes a API incompatibility with libav.

In all other cases where ff_rtmp_packet_read is used, the packet returned
is passed to rtmp_parse_result more or less immediately. In this single
case, the content of the packet was required to be a connect packet.

Some clients, e.g. Open Broadcaster Software, send a chunk size packet
before the connect packet. If the first packet is a chunk size packet,
handle it and read another one, requiring this to be a connect packet
instead.

Previously, if read_connect failed, the ret variable was unmodified
and had the value 0, indicating success, which then was returned from
the rtmp_open function, even though it actually failed.
