When a file is provided (via --all=FILE), let's use libmodprobe to load
the modules. This let's us use the logic in libmodprobe to parse the
provided modules load file -- FILE. The functional differences include:
- Removes the FILE parsing logic in modprobe.
- Returns early if FILE doesn't exist.
- Adds Dirname(FILE) to mod_dirs which means libmodprobe will parse the
modules.* files inside Dirname(FILE). Previously, modprobe would only
parse the modules.* files in the mod_dirs passed in by `-d DIR`. If
no directories were provided, we would fallback to the default
/lib/modules path. This patch removes the mod_dirs.empty() fallback
path when --all=FILE is used. It's unlikely anyone uses `--all=FILE`
without `-d DIR` unless FILE is inside the fallback path --
/lib/modules.

When a module is blocklisted, LoadWithAliases() will return an error
indicating the module failed to load. When the blocklist is requested
(via the -b parameter), let's not return an error if a blocklisted
module fails to load.

Due to GKI, the kernel UTS release string will not always (if ever)
match the vendor's UTS release string that is used to create the
initramfs file structure -- /lib/modules/<vendor uname>. This causes
module load failures when `-d DIR` is omitted. To fix this, we can
include all of the versions under /lib/modules that match the kernel's
major and minor version instead of directly using the value of uname().
In addition, we can also support modules being loaded directly from
/lib/modules.
Test: verify GKI kernel + initramfs with different UTS strings

Make the module directory optional by reading the kernel release
version. This path is where the kernel installs modules by default.
Similar behaviour can be found in several modprobe implementations.

Remove the function EnableBlocklist() and add a constructor argument to
enable/disable the use of modules.blocklist. In all cases, the
enabling/disabling of the blocklist happens immediately after creating
the Modprobe object. So this simplies libmodprobe.
Additionally, the use of the blocklist by libmodprobe should be enabled
by default unless explicitly disabled during creation of the Modprobe
object. Currently, only modprobe(8) defaults to not using the blocklist
and includes the argument -b BLOCKLIST for enabling it. That
functionality remains.
This refactor allows us to use the blocklist during first stage init.
However, additional logic is needed to not return an error for the
blocked non-aliased modules during first stage init; otherwise, the
error would result in an init crash leading to a device reboot. So fixup
LoadListedModules() to allow blocking modules without returning an
error.

There is a desire to ensure that modprobe as a service can log to
kmesg to help triage issues, so add support for the -s or --syslog
flag to do so.
SideEffects:
- help goes to stdout instead of stderr.
- verbose flag once, sets DEBUG, twice, sets VERBOSE minimum.
- quiet flag sets WARNING minimum.

Add a means to specify the modules to load from a file, rather than
on the argument list by adding an optional argument to the --all flag.
This allows modprobe to be designated as a standalone service to load
a long series of modules in the background and be specified
separately. The specified (module.load) file contains a newline
separate list of module names, and supports line comments using '#'
since this file may be maintained by a human or scripting that
requires tagging for regions of the file.

Some system services (e.g. SoundTriggerMiddleware) assume that
whenever they start, the audio HAL is in its default (reset) state.
init.rc scripts tie the lifetimes of the audio HAL and system
processes, but when using stop/start this is not the case, and this
may cause spurious crashes in this case.
stop/start is apparently being relied on in some test infrastructure,
so this change is needed to avoid causing problems for those systems
or false detection of problems, which are not actually present in
production.

Move these from toybox as they're Android specific and more easily
maintained here.
A few changes during the conversion:
* Report error in setprop if value is not a UTF8 string; this would
previously fail only after attempting to set the property
* Inform users to check dmesg for further failure messages for all
three programs
* Only start/stop zygote_secondary if the device is not single arch

So that the getevent output can be redirected and still be responsive
when events occur.
A good example is when using 'adb shell getevent' command, this latter
would only display the events when the buffer is full. With this patch
as soon as an event is received/printed, it is flushed to stdout.

adbd has been built as a static executable since the same binary was
copied to the recovery partition where shared library is not supported.
However, since we now support shared library in the recovery partition,
adbd is built as a dynamic executable.
In addition, the dependency from adbd to libdebuggerd_handler is removed
as debuggerd is handled by the dynamic linker.
A few more modules in /system/core are marked as recovery_available:
true as they are transitive dependencies of the dynamic linker.
This change also includes ld.config.recovery.txt which is the linker
config file for the recovery mode. It is installed to /etc/ld.config.txt
and contains linker namespace config for the dynamic binaries under
/sbin.
