This patch add a new system function $readmempath. It accepts
a ":" separated list of directories that $readmem{b,h} will
use when trying to open a given file. If the file given to
$readmem{b,h} starts with a '/' (an absolute path) the search
list will not be used. A new call to $readmempath will replace
the previous search list with the given list. The search list
elements are check to see if they exist and are directories.
If not a warning will be displayed and they will not be added
to the list.
