hw: separate bootstrap and core strictly * Introduce Hw namespace and library files under src/lib/hw * Introduce Bootstrap namespace * Move all initialization logic into Bootstrap namespace Ref #2388

base: remove include/spec/* other than ISA This commit moves the headers residing in `repos/base/include/spec/*/drivers` to `repos/base/include/drivers/defs` or repos/base/include/drivers/uart` respectively. The first one contains definitions about board-specific MMIO iand RAM addresses, or IRQ lines. While the latter contains device driver code for UART devices. Those definitions are used by driver implementations in `repos/base-hw`, `repos/os`, and `repos/dde-linux`, which now need to include them more explicitely. This work is a step in the direction of reducing 'SPEC' identifiers overall. Ref #2403

hw: switch page-tables only when necessary * Instead of always re-load page-tables when a thread context is switched only do this when another user PD's thread is the next target, core-threads are always executed within the last PD's page-table set * remove the concept of the mode transition * instead map the exception vector once in bootstrap code into kernel's memory segment * when a new page directory is constructed for a user PD, copy over the top-level kernel segment entries on RISCV and X86, on ARM we use a designated page directory register for the kernel segment * transfer the current CPU id from bootstrap to core/kernel in a register to ease first stack address calculation * align cpu context member of threads and vms, because of x86 constraints regarding the stack-pointer loading * introduce Align_at template for members with alignment constraints * let the x86 hardware do part of the context saving in ISS, by passing the thread context into the TSS before leaving to user-land * use one exception vector for all ARM platforms including Arm_v6 Fix #2091
