Avoid libgmp aborts by imposing limits
libgmp calls ‘abort’ when given numbers too big for its
internal data structures. The numeric limit is large and
platform-dependent; with 64-bit GMP 6.1.2 it is around
2**2**37. Work around the problem by refusing to call libgmp
functions with arguments that would cause an abort. With luck
libgmp will have a better way to do this in the future.
Also, introduce a variable integer-width that lets the user
control how large bignums can be. This currently defaults
to 2**16, i.e., it allows bignums up to 2**2**16. This
should be enough for ordinary computation, and should

Turn misc objects into pseudovectors
Eliminate the category of miscellaneous objects, and turn all
such objects into pseudovectors. The immediate motivation
for this change is to free up an enum Lisp_Type tag value, a

this change is worthwhile in its own right, as it improves
performance slightly on my platform, 0.3% faster for 'make
