Want a means to set the umem mtbf at runtine
100%
Description
libumem today has a private means of injecting failures into a program via the memory allocator. It would be great if we had a way to set this at run-time from a program so we can properly test the out of memory failure paths in various programs and routines without using allocator-specific kludges like trying to map right above the brk and eating up all of the memory, which would then make it harder to continue.
This adds a function umem_setmtbf which allows one to update the already existing umem functionality.

I tested this by using the functionality in the test suite for the memory streams (7092) work. They all behaved as expected and memory allocations properly failed.
