Removing 'memory-limit'

Removing 'memory-limit'

[Paul Eggert]

This is a heads-up for a proposed incompatible change to a rarely-used 
Emacs function. In Bug#24892 I propose declaring Emacs's memory-limit 
function to be obsolete, and changing it to be a placeholder that 
returns 0 everywhere (instead of its current practice of returning 0 on 
some platforms and nonzero values on others). The memory-limit function 
has been returning misleading or wrong information for years and as far 
as I know doesn't see significant use.
