Doug Moore b1290f4746 vm_reserv: use enhanced bitstring for popmaps ... vm_reserv.c uses its own bitstring implemenation for popmaps. Using the bitstring_t type from a standard header eliminates the code duplication, allows some bit-at-a-time operations to be replaced with more efficient bitstring range operations, and, in vm_reserv_test_contig, allows bit_ffc_area_at to more efficiently search for a big-enough set of consecutive zero-bits. Make bitstring changes improve the vm_reserv code. Define a bit_ntest method to test whether a range of bits is all set, or all clear. Define bit_ff_at and bit_ff_area_at to implement the ffs and ffc versions with a parameter to choose between set- and clear- bits. Improve the area_at implementation. Modify the bit_nset and bit_nclear implementations to allow code optimization in the cases when start or end are multiples of _BITSTR_BITS. Add a few new cases to bitstring_test.
