This adds a new "replaygain_preamp" option to the filter, and simply adds its
value to the replaygain gain value.

According to the ReplayGain spec, the peak amplitude may overflow and may result
in peak amplitude values greater than 1.0 with psychoacoustically coded audio,
such as MP3. Fully compliant decoders must allow peak overflows.

Additionally, having peak values in the 0<->UINT32_MAX scale makes it more
difficult for applications to actually use the peak values (e.g. when
implementing clipping prevention) since values have to be rescaled down.

This patch corrects the peak parsing by removing the rescaling of the decoded
values between 0 and UINT32_MAX and the 1.0 upper limit.

The gain sign was incorrectly decoded: since the FFSIGN() macro treats 0 as
negative, gain values starting with "0." were always decoded as negative.

Unbreaks compilation on arm due to conflicting types for
'ff_decode_block_coeffs_armv6'.

Configure will detect the availability of the Windows' console functions and set
HAVE_SETCONSOLETEXTATTRIBUTE.  Meaning av_log will use those functions to
control colours.  When ffmpeg is run in Cygwin's mintty terminal emulator it
will not use colour highlighting in this case.

Mintty responds to the usual escape code colours (it even supports 256 colours).
Windows' cmd.exe does not.  Fortunately it seems that Cygwin's emulation layer
now translates the basic 16 colours into Windows' Console command functions.

That means that we can have av_log use the standard colour commands and let
ffmpeg print colours in both mintty and cmd.
