* Allocate buffers dynamically vs statically.
* Now b[i] and i_fs and i_buf, are allocated dynamically.
* boot_calloc(size) allocates and zeros a buffer rounded to a NPG
* boundary.
* Generalize boot spec to allow, xx()/mach, xx(n,[a..h])/mach,
* xx([a..h])/mach, ...
* Also default "xx" if unspecified and alloc just "/mach",
* where everything is defaulted
* Add routine, ptol(), to parse partition letters.
