Some of these were made possible by moving several common macros to
libavutil/macros.h.
While just at it, also improve the other headers a bit.

SetConsoleTextAttribute used to be unavailable for Windows Store apps,
but is available to them now. But GetStdHandle still is unavailable,
thus make sure to check for both functions before using code that
requires both.

Adds the level prefix to all log messages, except those with level <=
AV_LOG_QUIET as they seem to be used for flushing the log buffer.

The new function behaves the same as av_log_format_line, but also forwards
the return value from the underlying snprintf call. This will allow
callers to accurately determine the size requirements for the line buffer.

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.

The default colors do not change in 256 more to keep
supporting people using Black on White, White on Black and
Solarized terminals.
