replacing all ifndef with pargma once All the kernel header files now use pargma once rather than the ifndef, as the pre-processed C files do not change while header files are protected with pargma once. This will also solve any naming issues caused by ifndef.

Convert license tags to SPDX identifiers This commit also converts our own copyright headers to directly use SPDX, but leaves all other copyright header intact, only adding the SPDX ident. As far as possible this commit also merges multiple Data61 copyright statements/headers into one for consistency.

aarch64: Move tpidrro_el0 from vcpu to tcb context This register is visible to software executing at EL0 but not writeable. Storing it in the VCPU context required custom save/restore handling as it had to be explicitly handled when switching from a VCPU thread to a non-VCPU thread so that it didn't become a channel. It is possible to now update this register via seL4_TCB_WriteRegisters for software executing at EL0. This also fixes a potential bug where if a vcpu-thread is switched for a non-vcpu-thread and then switched to a different vcpu-thread the original vcpu-thread's copy of this register will get set to 0.

RFC-3: Update user context for ARM with thread IDs Switched appropriate naming conventions. Was using the aarch64, have switched to aarch64 names. TIPDRURW -> tpidr_el0 TPIDRURO -> tpidrro_el0 TPIDRPRW -> tpidr_el1 Switch TLS register on aarch32 from TPIDURO (tpidrro_el0) to tpidr_ro so that it can be written to from user-land. Thread ID registers tpidr_el0 have been added to the user context for aarch32 and aarch64. Only the thread ID that is writeable from EL0 is saved in the TCB and saved/restored on context switch. Thread IDs that are only changed within a VM (the read-only thread ID for exception level 0 and the thread ID for exception level 1) are stored in the VCPU and saved and stored as part of VM enable/disable. Thread IDs that are only changed with VMs have been separated out into hypervisor code.
