When all of a composite device's components are ready, the composite is
created.  In this implementation, we always proxy components, even if
they're in the same process.  This will be relaxed in a later patch.

system/bin only contains appmgr, which is launched by full path.
/pkg/bin is not relevant to the shell, the shell should launch through the

The standalone version of Scudo is currently being upstreamed
in LLVM's compiler-rt, this is meant to provide a temporary way
for Fuchsia to use it as a replacement for jemalloc in musl.

Some of the files have already been reviewed and commited upstream,
while others haven't, and are likely to undergo some changes
during the review process.

The LLVM copyright header is present in all files, even the ones
that are not yet upstream, which I am not sure is legitimate.

BUILD.gn was provided by David. Note that hardware CRC32 is not
enabled.

Test: replace jemalloc with scudo in musl, fx full-build & fx run.

Some PCI devices like serial consoles and framebuffers are
brought online by the BIOS/bootloader and have existing BAR
allocations. For BAR bringup this was not maintained in the
userspace driver, but for continued work moving forward it
was necessary.

If the bus driver sees something that could be a valid address
in the address bits of a given device BAR then it will attempt
to allocate that address from the upstream allocator, if and only
if the device has been enabled prior to our probing. Unfortunately,
at power-on the state of all address bits are indeterminate, so
the best we can do is preserve any address we see present and then
attempt to use it. If we can allocate it then we don't need to change
anything and we can proceed. If not, then we allocate a properly
sized region from upstream and continue with BAR configuration.

This should match the existing behavior in the kernel PCI bus driver.

The ffmpeg demux node in mediaplayer occasionally gets a request
(from downstream) for a packet even when it has reported
end-of-stream on all streams. This happens only rarely.

https://fuchsia-review.googlesource.com/c/fuchsia/+/263095 addressed
the first-encountered DCHECK. That just got us to the next DCHECK.
This CL should prevent this failure in CQ going forward.

When an asynchronous method M is called on an object O, and O is deleted
before the callback is called, the callback should not be called later.

This fixes a couple of instance where the callback could be called after
the source object has been deleted.

O(logn) alloc and free time complexities.

Use IdAllocator to alloc and free blobfs inodes. The existing code uses
O(n). Not only allocation take a lot of time but it destroys the cpu
caches because it is walking array of blobfs_inode_t structure.

Around 128KiB should be sufficient for (1<<20) Ids.

Tested: Ran blobfs-test. Added id-alloc-bitmap test cases.

Performance: Test created 10000 blobs. In a 10000 iteration loop,
1. unlink first created and last created blobs
2. create two new blobs.

Creating two blobs would stress FindNode. Total time(ns) spent in

This patch moves the usb-virtual-bus into its own devmgr, and adds a test binding for it.
It also removes usb-virtual-bus functionality from usbctl, as this will be tested in an
automated fashion in a future CL.

In order to control the virtual bus, it is necessary to start an isolated devmgr
 and create a bindable device with BIND_PLATFORM_DEV_VID set to PDEV_VID_TEST and
BIND_PLATFORM_DEV_PID set to PDEV_PID_USB_VBUS_TEST.
Then; ioctls can be used to manipulate the virtual bus.

Test: Validate that usbctl no longer contains any virtual bus functionality, and that the virtual
bus is no longer visible in the device tree.

Rather than generating individual copy rules, we now use tests.json and
a Python script to copy host tests into the host_tests directory.

After this change, the host tests machinery can be driven entirely off
