Mint APE Loader v1.7

Browse source 
This change reduces the memory requirements of your APE Loader by 10x,
in terms of virtual memory size, thanks to the help of alloca(). We're
also now creating argument blocks with the same layout across systems.

*
* The following resources are recommended:
*
* - `RLIMIT_STACK` controls how much stack memory is available to the
* main thread. This setting is inherited across fork() and execve()
* Please note it's only safe for Cosmopolitan programs, to set this
* value to at least `PTHREAD_STACK_MIN * 2`. On Windows this cannot
* be used to extend the stack, which is currently hard-coded.
*
* - `RLIMIT_AS` limits the size of the virtual address space. This will
* work on all platforms except WSL. It is emulated on XNU and Windows
* which means it won't propagate across execve() currently.
