[MEMALLOC] Add pushstackmark

This patch gets rid of the stack mark tracking hack by allocating a little
bit of stack memory if we're at risk of planting a stack mark which may be
grown later.  To do this a new function pushstackmark is added which lets
the user pick a bigger amount to allocate since some users do that anyway
after setting a stack mark.
