Prior to this commit the kernel would always trigger a full reschedule
on setPriority. This change allows the kernel to attempt a direct
switch, avoiding invoking the scheduler.
Fixes a case where a thread can go from Running->Inactive->Restart and
use a restart PC that is out of date. An out of date restart PC occurs
when a thread was transitioned to running after being in a blocked
state, but was never scheduled and so did not execute the traps code
that updates the restart PC.
This also renames relevant register names for consistency across
architectures (FaultIP and NextIP).

Abbreviate Hoare triples that do not care about the return value and
whose pre and post conditions are the same.

Previously, the build system conditionally included Orphanage, but only
when built from run_tests. This meant that a plain ‘isabelle jedit’ or
‘make Refine’ would see a different session definition, resulting in a
slow rebuild.
NB: editing Orphanage now requires -l Refine instead of -l BaseRefine.
There were some sloppy last-minute changes that were not properly tested
and managed to evade testing. These contained a single logical omission
and a few typographic mistakes.
Session-qualified imports will be required for Isabelle2018 and help clarify
the structure of sessions in the build tree.
This commit mainly adds a new set of sessions for lib/, including a Lib
session that includes most theories in lib/ and a few separate sessions for
parts that have dependencies beyond CParser or are separate AFP sessions.
The group "lib" collects all lib/ sessions.
As a consequence, other theories should use lib/ theories by session name,
not by path, which in turns means spec and proof sessions should also refer
to each other by session name, not path, to avoid duplicate theory errors in
theory merges later.
A handle of fiddly proofs change slightly. A common offender involves
tcb_cap_cases, which should be unfolded with the ran_tcb_cap_cases
rule where possible rather than with tcb_cap_cases_def.
