The settings scope ipv6_scope refers specifically to IPv6 settings
that have a corresponding DHCPv6 option. Rename to dhcpv6_scope to
more accurately reflect this purpose.

Avoid generating syntactically invalid log messages by ensuring that
invalid characters are not present in the hostname. In particular,
ensure that any whitespace is stripped, since whitespace functions as
a field separator for syslog messages.

Note that IANA has not yet assigned a DHCPv6 option code for the
syslog server. When a code is assigned, the definition of
DHCPV6_LOG_SERVERS should be updated. Until then, an IPv6 address of
a syslog server can be configured manually using e.g.
set syslog6 3ffe:302:11:2::8309

[settings] Explicitly separate the concept of a completed fetched setting
The fetch_setting() family of functions may currently modify the
definition of the specified setting (e.g. to add missing type
information). Clean up this interface by requiring callers to provide
an explicit buffer to contain the completed definition of the fetched
setting, if required.

[syslog] Pass internal syslog() priority through to syslog console
Use a private ANSI escape sequence to convey the priority of an
internal syslog() message through to the syslog server.

[console] Do not share ANSI escape context between lineconsole users
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.

[console] Exclude text-based UI output from logfile-based consoles
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.

[console] Allow usage to be defined independently for each console
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

[syslog] Separate out generic line-based console functionality
Abstract out the generic line-handling portions of the syslog
putchar() routine, to allow use by other console types.

[syslog] Disable console when no syslog server is defined
Explicitly disable the syslog console when no syslog server is
defined, rather than (ab)using the socket family address as an
equivalent console-enabled flag.

Improve the appearance of the "config" user interface by ensuring that
settings appear in some kind of logical order.
