* Add an enumeration entry for when we're not running under a hypervisor;
  today UNKNOWN is used for 'all non-KVM and all physical'.

  This allows code elsewhere in the kernel to see whether we're running
  under a hypervisor or not, so we can apply certain workarounds if
  needed.

* Modify select_microarch_config to take the x86 uarch enum by parameter
  rather than global and have it return the selected config operations
  table.

I'd like to move towards an interface for code throughout the kernel to
query decoded CPUID feature bits/synthetic feature bits/family-model-
stepping data. The interface would allow writing tests for particular
F/M/S targets. Marking the globals as such is a start towards that.

All existing users have been migrated to
'deprecated-global-persistent-storage', which is protected by a
whitelist. New users must use 'isolated-persistent-storage' instead.

Fuzzing tests have been broken for a while now because of assumptions
made about /data across namespaces, and this wasn't caught because they
don't run continuously (and no one complained). SEC-200 filed to fix
them.

test -t is known to be imperfect, however, it should be sufficiently portable

The 'Type' enum class in common::DeviceAddress has only 4 options, but
defaults to a 32bit int, which due to alignment causes DeviceAddress to
be 12 bytes. Switching to an explicit uint16_t allows the entire class
to be packed into 8 bytes, which will allow it to fit in a 64-bit
register and is likely to generally improve memory usage and performance.

This is a temporary workaround for ZX-3284, which is causing iquery
operations to hang occasionally.

The problem is that components who are resumed from a suspended state
occasionally miss events waiting on a channel. This change adds a new
FilePoker class that takes the path of a directory that will soon be opened.
If the operation to open that file happens to hang, a thread wrapped by
FilePoker will attempt to open the directory, which unsticks the
process.

This hack uncovered a possible additional problem with thread
suspension, but it is far more rare than the original issue.

This consolidates the package definition files for many command line
tools in the garnet directory to the //garnet/packages/tools directory

unit.

This leaves a few forwarding declarations behind for packages
referenced from topaz.git.

This change replaces iquery's manual traversal code with the new
inspect/reader.h interface.

To simplify iquery path handling and to make parts of the path more
clear, this change also introduces a delimiter between the file part and
inspect part of a particular path.

Consider the inspect tree:
objects:
 table-0x0:
  row-0x1:
 table-0x2:

Previously we would write:
$ iquery --ls --full_paths objects/table-0x0
objects/table-0x0/row-0x1

Now we write:
$ iquery --ls --full_paths objects#table-0x0
objects#table-0x0/row-0x1

The delimiter '#' separates the file part of the path from the inspect
part, which makes the meaning more clear ("open inspect at this
location, then traverse to this child" vs. "expect to find an inspect
endpoint along this path and once that is open continue traversing to
the proper location").
