Axel Dörfler b9074efcb7 * Fixed the "vnodes" KDL command when called without any arguments.
* Fixed the usage text of the "help" KDL command.
* Made the "ambiguous command" warning shorter, so that it will still fit in
  the exception buffer.

Ingo Weinhold 15f1e19781 * Added support for the "--help" argument to some debugger commands.
* The kernel debugger does now define some temporary variables when
  entered (current thread and team, etc.).

Ingo Weinhold 3b4fa1664e * Implemented parse_expression(). The back-end is an expression parser
that is a little more powerful than BeOS'. It features:
  - Persistent and temporary uint64 variables. The former kind is set
    only by the user. The latter (those prefixed "_") can be set
    automatically by commands, thus e.g. making it easier to access
    members of a dumped structure. They are unset when the next command
    is invoked. The special temporary variable "_" is defined as a
    command's return value.
  - Expressions can contain nested command invocations using brackets
    ("[ ... ]").
  - Command lines are parsed by the expression parser, too. They can
    contain command invocations (in brackets) and expressions (in
    parentheses).
* Added debugger commands:
  - expr: Evaluates the given expression and prints the result.
  - unset: Undefines a variable.
  - vars: Prints the values of all defined variables.
* Moved debugger command code into its own source file.

Ingo Weinhold 07b8a5de22 * Sort the registered commands by name when entering KDL.
* Don't execute a command anymore, if the given prefix is ambiguous.
* Added tab completion for commands.
* Added on-the-fly help while typing a command line. It is triggered
  by pressing tab at a position after the space following the command.
  It is implemented by calling the command with argument "--help", which
  doesn't work yet with most commands, but some already print their
  usage in this case.
