In Isabelle2020, when isabelle jedit is started without a session
context, e.g. `isabelle jedit -l ASpec`, theory imports with path
references cause the isabelle process to hang.
Since sessions now declare directories, Isabelle can find those files
without path reference and we therefore remove all such path references
from import statements. With this, `jedit` and `build` should work with
and without explicit session context as before.

The previous implementation of IOPortCaps has problems with revocability
and determining parency etc. This commit adds IOPortControlCaps which
behave identically to IRQControlCaps -- invoking the IOPortControlCap
allows one to create IOPortCaps with the supplied range.
There now exist invariants to show that there is only one
IOPortControlCap and that all IOPortCaps in the system do not overlap.
Furthermore there is a global record of which IO ports have been
allocated to prevent reissuing the same ports.
In X64 update the following to match the C kernel:
- TCB size-bits (11).
- Endpoint size-bits (4).
- Guard bits (58).
- Message registers.
For all architectures, replace magic numbers with defined constants in
specifications, and as far as possible in proofs:
- tcb_bits in abstract spec.
- tcbBlockSizeBits, cteSizeBits, ntfnSizeBits, epSizeBits in Haskell
spec, Haskell and C refinement proofs.
