Add define command for defining macros
Macros are parsed when they are defined with the D command and can
subsequently be used as arguments for other commands.
Handle out of memory errors directly in tok.c.

| 500 <para>Define the macro <replaceable>name</replaceable> to expand to | |
| 501 <replaceable>value</replaceable>. A Macro is a shorthand term for | |
| 502 a command and/or command arguments. Macros are tokenized when they | |
| 503 are defined, thus if a macro contains other macros, these other | |
| 504 macros are expanded once at the time the macro is defined and not | |
| 505 each time a macro is expanded later. A macro can be used as like a | |
| 506 command or as part of the command's argument by prefixing the macro | |
| 507 name by a "$". It is expanded by substituting the | |
| 508 previously tokenized contents before the command is | |
| 509 evaluated.</para> | |
