David Lamparter 87f44e2f0b lib: add minimal no-config VTY mode 
This silences the following warning from watchquagga:
"Can't save to configuration file, using vtysh."
which otherwise appears when doing a "write file" in vtysh when no
integrated-config is in use.

Also make "show memory" available in watchquagga.

*
* Name of the function that will be defined.
*
* cmdname
* =======
*
* Name of the struct that will be defined for the command.
*
* cmdstr
* ======
*
* The cmdstr defines the command syntax. It is used by the vty subsystem
* and vtysh to perform matching and completion in the cli. So you have to take
* care to construct it adhering to the following grammar. The names used
* for the production rules losely represent the names used in lib/command.c
*
* cmdstr = cmd_token , { " " , cmd_token } ;
*
* cmd_token = cmd_terminal
* | cmd_multiple
* | cmd_keyword ;
*
* cmd_terminal_fixed = fixed_string
* | variable
* | range
* | ipv4
* | ipv4_prefix
* | ipv6
* | ipv6_prefix ;
*
* cmd_terminal = cmd_terminal_fixed
* | option
* | vararg ;
*
* multiple_part = cmd_terminal_fixed ;
* cmd_multiple = "(" , multiple_part , ( "|" | { "|" , multiple_part } ) , ")" ;
*
* keyword_part = fixed_string , { " " , ( cmd_terminal_fixed | cmd_multiple ) } ;
* cmd_keyword = "{" , keyword_part , { "|" , keyword_part } , "}" ;
*
* lowercase = "a" | ... | "z" ;
* uppercase = "A" | ... | "Z" ;
* digit = "0" | ... | "9" ;
* number = digit , { digit } ;
*
* fixed_string = (lowercase | digit) , { lowercase | digit | uppercase | "-" | "_" } ;
* variable = uppercase , { uppercase | "_" } ;
* range = "<" , number , "-" , number , ">" ;
* ipv4 = "A.B.C.D" ;
* ipv4_prefix = "A.B.C.D/M" ;
* ipv6 = "X:X::X:X" ;
* ipv6_prefix = "X:X::X:X/M" ;
* option = "[" , variable , "]" ;
* vararg = "." , variable ;
*
* To put that all in a textual description: A cmdstr is a sequence of tokens,
* separated by spaces.
*
* Terminal Tokens:
*
* A very simple cmdstring would be something like: "show ip bgp". It consists
* of three Terminal Tokens, each containing a fixed string. When this command
* is called, no arguments will be passed down to the function implementing it,
* as it only consists of fixed strings.
*
* Apart from fixed strings, Terminal Tokens can also contain variables:
* An example would be "show ip bgp A.B.C.D". This command expects an IPv4
* as argument. As this is a variable, the IP address entered by the user will
* be passed down as an argument. Apart from two exceptions, the other options
* for Terminal Tokens behave exactly as we just discussed and only make a
* difference for the CLI. The two exceptions will be discussed in the next
* paragraphs.
*
* A Terminal Token can contain a so called option match. This is a simple
* string variable that the user may omit. An example would be:
* "show interface [IFNAME]". If the user calls this without an interface as
* argument, no arguments will be passed down to the function implementing
* this command. Otherwise, the interface name will be provided to the function
* as a regular argument.
* Also, a Terminal Token can contain a so called vararg. This is used e.g. in
* "show ip bgp regexp .LINE". The last token is a vararg match and will
* consume all the arguments the user inputs on the command line and append
* those to the list of arguments passed down to the function implementing this
* command. (Therefore, it doesn't make much sense to have any tokens after a
* vararg because the vararg will already consume all the words the user entered
* in the CLI)
*
* Multiple Tokens:
*
* The Multiple Token type can be used if there are multiple possibilities what
* arguments may be used for a command, but it should map to the same function
* nonetheless. An example would be "ip route A.B.C.D/M (reject|blackhole)"
* In that case both "reject" and "blackhole" would be acceptable as last
* arguments. The words matched by Multiple Tokens are always added to the
* argument list, even if they are matched by fixed strings. Such a Multiple
* Token can contain almost any type of token that would also be acceptable
* for a Terminal Token, the exception are optional variables and varag.
*
* There is one special case that is used in some places of Quagga that should be
* pointed out here shortly. An example would be "password (8|) WORD". This
* construct is used to have fixed strings communicated as arguments. (The "8"
* will be passed down as an argument in this case) It does not mean that
* the "8" is optional. Another historic and possibly surprising property of
* this construct is that it consumes two parts of helpstr. (Help
* strings will be explained later)
*
* Keyword Tokens:
*
* There are commands that take a lot of different and possibly optional arguments.
* An example from ospf would be the "default-information originate" command. This
* command takes a lot of optional arguments that may be provided in any order.
* To accomodate such commands, the Keyword Token has been implemented.
* Using the keyword token, the "default-information originate" command and all
* its possible options can be represented using this single cmdstr:
* "default-information originate \
* {always|metric <0-16777214>|metric-type (1|2)|route-map WORD}"
*
* Keywords always start with a fixed string and may be followed by arguments.
* Except optional variables and vararg, everything is permitted here.
*
* For the special case of a keyword without arguments, either NULL or the
* keyword itself will be pushed as an argument, depending on whether the
* keyword is present.
* For the other keywords, arguments will be only pushed for
* variables/Multiple Tokens. If the keyword is not present, the arguments that
* would have been pushed will be substituted by NULL.
*
* A few examples:
* "default information originate metric-type 1 metric 1000"
* would yield the following arguments:
* { NULL, "1000", "1", NULL }
*
* "default information originate always route-map RMAP-DEFAULT"
* would yield the following arguments:
* { "always", NULL, NULL, "RMAP-DEFAULT" }
*
* helpstr
* =======
*
* The helpstr is used to show a short explantion for the commands that
* are available when the user presses '?' on the CLI. It is the concatenation
* of the helpstrings for all the tokens that make up the command.
*
* There should be one helpstring for each token in the cmdstr except those
* containing other tokens, like Multiple or Keyword Tokens. For those, there
* will only be the helpstrings of the contained tokens.
*
* The individual helpstrings are expected to be in the same order as their
* respective Tokens appear in the cmdstr. They should each be terminated with
* a linefeed. The last helpstring should be terminated with a linefeed as well.
*
* Care should also be taken to avoid having similar tokens with different
* helpstrings. Imagine e.g. the commands "show ip ospf" and "show ip bgp".
* they both contain a helpstring for "show", but only one will be displayed
* when the user enters "sh?". If those two helpstrings differ, it is not
* defined which one will be shown and the behavior is therefore unpredictable.
