Increase MALLOC_MP_LIM to 16MB
Increase the maximum allowed size passed to mprotect(PROT_WRITE)
from 1MB to 16MB. This was necessary with the glibc allocator
in order to allow worker threads to allocate more memory --
which in turn is necessary because of our new use of worker
threads for compression.
Closes ticket #22096. Found while working on #21648.
