vlog: Be more liberal in syntax for -v and vlog/set.

Browse Source 
Until now, the argument to -v and vlog/set has had to take the form
"module:facility:level".  I can never remember the required order, so this
commit switches to allowing any order.

.SS "VLOG COMMANDS"
These commands manage \fB\*(PN\fR's logging settings.
.IP "\fBvlog/set\fR \fImodule\fR[\fB:\fIfacility\fR[\fB:\fIlevel\fR]]"
Sets the logging level for \fImodule\fR in \fIfacility\fR to
\fIlevel\fR:
.IP "\fBvlog/set\fR [\fIspec\fR]"
Sets logging levels. Without any \fIspec\fR, sets the log level for
every module and facility to \fBdbg\fR. Otherwise, \fIspec\fR is a
list of words separated by spaces or commas or colons, up to one from
each category below:
.
.RS
.IP \(bu
\fImodule\fR may be any valid module name (as displayed by the
\fB\-\-list\fR action on \fBovs\-appctl\fR(8)), or the special name
\fBANY\fR to set the logging levels for all modules.
A valid module name, as displayed by the \fBvlog/list\fR command on
\fBovs\-appctl\fR(8), limits the log level change to the specified
module.
.
.IP \(bu
\fIfacility\fR may be \fBsyslog\fR, \fBconsole\fR, or \fBfile\fR to
set the levels for logging to the system log, the console, or a file
respectively, or \fBANY\fR to set the logging levels for both
facilities. If it is omitted, \fIfacility\fR defaults to \fBANY\fR.
.IP
The log level for the \fBfile\fR facility has no effect unless
\fB\*(PN\fR was invoked with the \fB\-\-log\-file\fR option.
\fBsyslog\fR, \fBconsole\fR, or \fBfile\fR, to limit the log level
change to only to the system log, to the console, or to a file,
respectively.

.IP \(bu
\fIlevel\fR must be one of \fBoff\fR, \fBemer\fR, \fBerr\fR, \fBwarn\fR,
\fBinfo\fR, or
\fBdbg\fR, designating the minimum severity of a message for it to be
logged. If it is omitted, \fIlevel\fR defaults to \fBdbg\fR.
\fBoff\fR, \fBemer\fR, \fBerr\fR, \fBwarn\fR, \fBinfo\fR, or
\fBdbg\fR, to control the log level. Messages of the given severity
or higher will be logged, and messages of lower severity will be
filtered out. \fBoff\fR filters out all messages. See
\fBovs\-appctl\fR(8) for a definition of each log level.

.IP
Case is not significant within \fIspec\fR.
.IP
Regardless of the log levels set for \fBfile\fR, logging to a file
will not take place unless \fB\*(PN\fR was invoked with the
\fB\-\-log\-file\fR option.
.IP
For compatibility with older versions of OVS, \fBany\fR is accepted as
a word but has no effect.
.RE
.IP "\fBvlog/set PATTERN:\fIfacility\fB:\fIpattern\fR"
Sets the log pattern for \fIfacility\fR to \fIpattern\fR. Refer to
