An ANSI escape sequence context cannot be shared between multiple
users. Make the ANSI escape sequence context part of the line console
definition and provide individual contexts for each user.

The output from text-based user interfaces such as the "config"
command is not generally meaningful for logfile-based consoles such as
syslog and vmconsole.

Add the concept of a "console usage", such as "standard output" or
"debug messages". Allow usages to be associated with each console
independently. For example, to send debugging output via the serial
port, while preventing it from appearing on the local console:
#define CONSOLE_SERIAL CONSOLE_USAGE_ALL
#define CONSOLE_PCBIOS ( CONSOLE_USAGE_ALL & ~CONSOLE_USAGE_DEBUG )
If no usages are explicitly specified, then a default set of usages
will be applied. For example:
#define CONSOLE_SERIAL
will have the same affect as
#define CONSOLE_SERIAL CONSOLE_USAGE_ALL
