We have already switched to using a more direct path to create virtcons,
this removes the old path through /dev/misc/dmctl to the devcoordinator.

Issue: ZX-3403
Test: Booted frank, virtcon still works, this change is in essence a
no-op as nothing is using this code.

Apparently using data_deps in compiled_action will not trigger a
re-execution of the tool when fidlgen_llcpp changes. Out of these
following potential locations for the fidlgen dependency I tried:

- in data_deps in executable("fidlgen_llcpp_zircon")
- in deps in executable("fidlgen_llcpp_zircon")
- in data_deps in the compiled_action
- in deps in the compiled_action

Only the last one will correctly trigger the execution of
fidlgen_llcpp_zircon.

Also need to put fidlgen_llcpp in the depfile of the update/validate
actions, to indicate dependency on incremental builds.

TEST: Edit a .go source file in fidlgen_llcpp and observe that
fx build -k 0 tools/fidlgen_llcpp_zircon:update is correctly run and
modifies the checked in bindings.

BaseView::PresentScene() expects single call in a vsync, but BaseView::Present()
can queue multiple calls, i.e. simplest_app example. For the following calls, it
is OK to skip as they will fall into the same vsync interval. This CL removes
the checks for that case.
However, this check would make sense for InvalidateScene() driven updates, so
I noted that we should bring it back when that is the only option.

Goldfish address space is a virtual device that is used
by AEMU to provide host visible memory when forwarding
Vulkan API from guest to host.

Goldfish address space is a PCI device that provides
a region of memory that can be used for mapping host side
memory into guest. Guest side Vulkan driver can reserve a

write_msr_safe attempts to write a value to an MSR; if it encounters a #GP
fault, it returns a status with the value unwritten.

Like read_msr_safe, this should be executed with interrupts disabled; I
plan to change both of them soon to assert that we are either cpu-pinned
or have hard interrupts disabled.

Tested: See 4th CL in stack; adds 'k' commands to access read_msr/write_msr.

exercise these.

This doesn't cause a change in behavior. The code is only used for
examples and the change simply increase hw support and allows for
optimizations in future drivers.

- Determine memory type index instead of assuming 0.
- This is a memory allocation dedicated to a single image. Inform
  the driver of this. Required by goldfish ICD and useful for
  other drivers.

The result of this change is that examples that use this layer can
be used when running fuchsia on aemu.

This changelist introduces persistent storage for retaining settings
accessed through the SetUI service. The functionality is exposed
through two main traits. The Store trait defines an API for writing
and retrieving values, while the SettingCodec trait defines an
encoding/decoding protocol. Concrete implementations for both
have been provided, using JSON for the latter.

Note that the codecs must be updated to support new SettingData
types. The JSON codec currently only supports StringValue and
AccountSettings.

This starts a component_test_runner which is an implementation of the
fuchsia.sys.Runner interface that can instantiate a component within an
environment configured for tests.  The specification of the test
environment and of the component under test is the component manifest
itself. This way a test author can configure different environments to
run a test in without having to modify the code for the component under
test.

This patch responds to incoming Runner requests and starts parsing the
test specification data, but doesn't yet actually attempt to create the
test environment or actually instantiate the component.

Also add an explicit option in environment() to enable a per-variant
libprefix in all variants of a toolchain (or none).  By default, each
variant that has the "instrumented" tag gets "$variant/" appended to its
${toolchain.libprefix} value.  Remove the "asan" variant's explicit
toolchain_vars.libprefix setting, which is now redundant.

The dynamic linker is compiled to request the libprefix from the loader
service, and all executables have the prefixed name in PT_INTERP so they
get the same variant's dynamic linker.

Additionally, some minor related changes:
- Remove unused "FormatMinfs" function.
- Plumb the "Should we check filesystems?" boolean through explicit
arguments instead of environment variables.
- Make minfs superblock validation more strict. This validates that
clients can't format a filesystem with N blocks, and either mount
of check the consistency of a filesystem with M blocks, for M < N.
This change, along with the fshost tests, acts as a regression for
a bug where the consistency checker only inspected a subsection of the
filesystem.
