Remove all the redundant external declarations of exception vectors and runtime setting of the pointers that's scattered around various places.
Remove all traces of support for ARM chips prior to the arm9 series.
Make the default exception handler vectors point to where I thought they were already pointing: the default handlers (not a panic that says there is no default handler).
Eliminate irq_dispatch.S. Move the data items it contained into arm/intr.c and the functionality it provided into arm/exception.S.
Move the exception vector table (so-called "page0" data) into exception.S and eliminate vectors.S.
Change the way the asm GET_CURTHREAD_PTR() macro is defined so that code using it doesn't have to have an "AST_LOCALS" macro somewhere in the file.
Arrange for arm fork_trampoline() to return to userland via the standard swi_exit code in exception.S instead of having its own inline expansion of the DO_AST and PULLFRAME macros.
Now that the PUSHFRAME and PULLFRAME macros are used only in the swi entry/exit code, they don't need to be macros. Except that didn't work and the whole change was reverted.
Remove some unnecessary indirection and jump right to the handler functions.
Use panic rather than printf to "handle" an arm26 address exception (should never happen on arm32).
Remove the unreferenced DATA() macro.
Remove #include <machine/asmacros.h> from files that don't need it.

Replace the C implementation of __aeabi_read_tp with an assembly version. This ensures we follow the ABI by preserving registers r1-r3.

Fix 2 bugs :
- A race condition could happen if two threads were using RAS at the same time as the code didn't reset RAS_END, the RAS code could believe we were not in a RAS, when we were in fact. - Using signed value logic to compare addresses wasn't such a good idea.
Many thanks to Ian to investigate on these issues.

Improve ARM_TP_ADDRESS and RAS area.
De-hardcode usage of ARM_TP_ADDRESS and RAS local storage, and move this special purpose page to a more convenient place i.e. after the vectors high page, more towards the end of address space. Previous location (0xe000_0000) caused grief if KVA was to go beyond the default limit.
Note that ARM world rebuilding is required after this change since the location of ARM_TP_ADDRESS is shared between kernel and userland.

Instead of using sysarch() to store-retrieve the tp, add a magic address, ARM_TP_ADDRESS, where the tp will be stored. On CPUs that support it, a cache line will be allocated and locked for this address, so that it will never go to RAM. On CPUs that does not, a page is allocated for it (it will be a bit slower, and is wrong for SMP, but should be fine for UP). The tp is still stored in the mdthread struct, and at each context switch, ARM_TP_ADDRESS gets updated.

Implement two new sysarch for arm, ARM_GET_TP and ARM_SET_TP, to work around the lack of tls on arm.
