For commands with this flag set, the parser won't parse the
arguments provided (it will only check for matching parentheses and
brackets), but will pass the unparsed argument list string to the
command instead.
* Set the new flag for the "expr" command, so one doesn't have to quote
the expression to evaluate anymore (or put it in parentheses).
* Fixed tokenizing of quoted and unquoted strings in expression mode.

command usage texts, which can be too long for kprintf().

invoke_debugger_command() is now automatically preceded by
"usage: <command name>", so the string passed to
add_debugger_command_etc() shouldn't contain it anymore.

add_debugger_command(), but additionally takes parameters "usage"
and "flags".
* Added add_debugger_command_alias() which creates another name for an
existing command.
* Added print_debugger_command_usage() to print a command's usage.
* invoke_debugger_command() intercepts invocations with "--help" and
prints the command's usage text, if it is known. If unknown, the
command will be called normally.
* Made use of the new functions in debug.cpp.

* 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.

* The kernel debugger does now define some temporary variables when
entered (current thread and team, etc.).

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.

* 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.
