x86-32: use brk segment for allocating initial kernel pagetable
Impact: use new interface instead of previous ad hoc implementation Rather than having special purpose init_pg_table_start/end variables to delimit the kernel pagetable built by head_32.S, just use the brk mechanism to extend the bss for the new pagetable. This patch removes init_pg_table_start/end and pg0, defines __brk_base (which is page-aligned and immediately follows _end), initializes the brk region to start there, and uses it for the 32-bit pagetable.
