This requires a bit of refactoring: moving things around.
libinit_host is used by host_apex_verifier which needs check_builtins as
well.

This reverts commit aeccbb8f3a.
Reason for revert: needed for debug and investigations of battery and charging issues. The tooling depends on these lines (and have been for years). You should have these lines only on SOC changes and in the presence of a serious problem. Please do not remove logging without consulting with the BMS SW team first.

With a device capable of saturating the bus at SuperSpeed+,
the next bottleneck is the fixed (size-independent) overhead of
the usbfs ioctl() system calls, which includes entering/exiting
the kernel, allocating/deallocating a contiguous buffer for DMA,
configuring/deconfiguring the IOMMU and issuing the DMA to the HC. In
order to saturate the bus from the host software perspective, we must
reach the schedule() call in reap_as() before the next interrupt from
the HC indicating the completion of the URB.
In my experimental setup, with an SS+ capable host and device
and 16 KiB URBs, we reach the schedule() call in 25us, but the
URB is serviced in an estimated 16us, so we lose roughly a third
of the bandwidth. Increasing the URB size to 64KiB there are
65us between interrupts and 55us until schedule(). This means
we usually reach schedule() in time but not always, so we lose a
bit of bandwidth. Increasing it again to 128KiB and we have 128us
between interrupts and 65us until schedule(), so we're now comfortably
saturating the bus. In order to account for differences between hosts,
this CL uses a doubled maximum of 256KiB.
With larger allocation sizes we now risk contiguous allocation
failures, so I implemented a fallback where we try smaller sizes if
a larger one fails.
With this CL download speeds on my hosts are now around 980 MB/s over
SS+ and 440 MB/s over SS.

/metadta/aconfig/boot dirs
Create aconfig dirs on /metadata to store aconfig storage related files.
Under /metadata/aconfig we will store the following pb files:
1, aconfig_storage_location.pb, store the location of the storage files for
each container.
2, aconfig_flag_persistent_overrides.pb, store the local flag value overrides.
Under /metadata/aconfig/flags we will store flag value and info files
for each container, this include:
1, <container_name>.val flag value file
2, <container_name>.info flag info file
Under /metadata/aconfig/boot we will store read only flag value files
copied from /metadata/aconfig/flags at boot. These read only files are
used to serve flag read queries.

In newer versions of libc++, std::char_traits<T> is no longer defined
for non-character types, and a result, std::basic_string<T> and
std::basic_string_view<T> are also no longer defined for non-character
types. See
https://discourse.llvm.org/t/deprecating-std-string-t-for-non-character-t/66779.
Replace them with std::vector<T> and std::span<const T>.

If the system time changes during the execution of fastboot we might
see some strange output such as:
Sending sparse 'super' 4/20 (254972 KB) OKAY [-516.263s]
Fix it by changing now() to use clock_gettime(CLOCK_MONOTONIC).
I confirmed that all callers of now() are using it for relative time
and not time since the epoch.

The fastboot command currently uses USBDEVFS_BULK to transfer data
(including image data) to the target. On the kernel side it looks
like this:
1. Allocate a contiguous memory region and copy the user data into
the memory region (which may involve accessing storage).
2. Instruct the driver to start a DMA operation.
3. Wait for the DMA to finish.
This is suboptimal because it misses out on a pipelining
opportunity. We could be doing 3 for the current operation in parallel
with 1 for the next operation, so that the next DMA is ready to go
as soon as the current DMA finishes.
The kernel supports asynchronous operations on usbdevfs file
descriptors (USBDEVFS_SUBMITURB and USBDEVFS_REAPURB), so we can
implement this like so:
1. Submit URB 0
2. Submit URB 1
3. Wait for URB 0
4. Submit URB 2
5. Wait for URB 1
and so on.
That is what this CL implements. On my machine it increases transfer
speed from 125 MB/s to 160 MB/s using a USB 3.0 connection to the
target (Pixel 8).

Two things need changing for debuggerd_test to pass.
1. The seccomp policy needs to allow for PROT_MTE (0x20) in both
mprotect() and mmap(). Stack MTE processes do a mprotect()/mmap() of
the stack when launching a process.
2. The fault address and stack pointer need to be untagged when trying
to figure out the stack overflow cause.

This is needed to upgrade the android_logger crate from 0.12.0
to 0.13.3.
with_max_level provides the same functionality as with_min_level.
The renaming is admittedly confusing, but the new name is accurate
and it makes sense that they deprecated and then removed the
previously poorly named with_min_level.
See crate documentation [1] and code [2].
