hv_exc: Handle M1RACLES mitigation here due to 12.0 spam
...
macOS 12.0 added a silly ineffective "mitigation" that clears the
register on every context switch. This doesn't actually mitigate
anything, but it does make this sysreg trap performance-critical,
so we have to move its handling into the C side.

Add command categories to reduce command clutter
...
Based on a suggestion from Ludwig Schubert it now uses the inspect class
to generate signatures of the functions for the help messages and
the qualified names which is a big improvement.
Also greatly reduced the clutter by putting the class functions into seperate
categories based on their class name. Now the top level help fits on one
page making it much more readable.

Shell: do not access properties on startup
...
Change the way the shell finds methods to add to the locals on startup: the
methods are queried on the object’s class, rather than the object itself. This
allows detecting if an object’s member is a property and ignore it, rather than
accessing the property.
Attributes whose name starts by ‘_’ are also now ignored, which avoids
importing private methods or Python magic methods in the shell namespace.
Fixes spurious accesses to ProxyUtils’s SIMD properties (b, h, etc) on shell
startup, which caused a ProxyCommandError if m1n1 is not recent enough.

hv: shadow perf monitor IRQ mode and state
...
The development Mac OS kernel panics if the PMCR0 sysreg is in an
unexpected state. To avoid that the hypervisor needs to shadow the
interrupt mode and interrupt active flag after it mask the PM FIQ.
Mac OS reads and writes frequently from PMCR0 and PMC 0/1 so handling
in m1n1 is preferred over Python.

Add an option to disable checksumming if possible
...
* Introduce feature flags which allows the proxy and m1n1 to determine which
features they have in common.
* Add a feature flag that disables checksumming (by replacing checksums with
constant values) for the data packets exchanged by REQ_MEMREAD, REQ_MEMWRITE
and REQ_EVENT. The feature is enabled if m1n1 supports it; checksumming is kept
enabled for UART communication.
* To ensure no packet loss when checksumming is disabled, an extra sentinel
value is added after the exchanged data for memory read/write operations.

Implement calling code as EL1
...
This works by clearing HCR_EL2.TGE, and then doing essentially the same
thunk/return dance as for EL0 calls. However, since most EL1 exceptions
are not routed to EL2, we install hypercall vectors in EL1 to forward
them to EL2, and then short circuit the exception return to whatever
triggered the original exception.

exception: implement el0_call to run code as EL0
...
This lets us test register access and other features from EL0.
No serious attempt at security is made, but at least EL0 runs off of a
separate stack and can return to EL2 at any time with `brk`; we can
easily implement a guard mode to break straight to EL2 on exception
later if needed.

memory: prepare for EL0 support
...
Enable EL0 access to MMIO/etc, but not main RAM, because AArch64
architecturally enforces EL0w ^ EL2x.
Instead, create an alias of main RAM to grant EL0 full permissions,
at 0x80_0000_0000.
Grant EL0 full access to MMIO stuff, since EL2 will never execute
from there.

Add heapblock and dlmalloc for managing memory
...
heapblock is a simple `sbrk` style implementation, also useful as an
"endless" decompression buffer. dlmalloc is used on top as a malloc
implementation.
This also changes how the Python side manages its heap. We still use a
python-side malloc implementation (since this is faster), and we put the
Python heap at the m1n1 heap + 128MB, without allocating it.
Hopefully this should never step on anything m1n1 neads, and avoids
having to manage freeing across Python script calls.
