A lot of things had moved out of system/core/ without their TEST_MAPPING
entries having gone with them, reducing the amount of presubmit coverage
for those things.
In order to reduce the likelihood of that happening again, I've pushed
all that remained in the system/core/ TEST_MAPPING down into the
individual subdirectories.

adb_debug.prop is migrated too. And ramdisk_available is added to all
dependencies.

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.

The first argument in a modules.dep line must end with a colon so fail
if that condition is not met.

Only the parent executable, not libraries should set this value.
Note that `modprobe` in toolbox and first stage init, the two primary
users of this library already set this same minimum log severity.

modprobe command no longer uses EnableVerbose, opting to do the
associated operations directly.

In the short term this will be used to help implement support for
multiple kernel module directories but it may be useful in other
contexts as well.

In recovery mode, load modules from modules.load.recovery if it
exists. Otherwise load from modules.load as usual.

For modprobe operation.
For an interlocking driver set of about 50 modules, the impact of
their dependencies resulted in a 30 second impact in boot time
trying to load previously loaded modules. This impact is handily
eliminated by keeping a list of modules paths that have been loaded
and skipping them proactively.
Test: Confirmed device boot and 50 module set of drivers functions.

* changes:
toolbox: add modprobe
libmodprobe: add verbose mode
libmodprobe: add GetAllDependencies
libmodprobe: add support to list modules
libmodprobe: add support for a blacklist
libmodprobe: support parameters in LoadWithAliases
libmodprobe: add support to remove modules
libmodprobe: make name canonical in LoadWithAliases
libmodprobe: make available in vendor
Add support to specify module parameters in LoadWithAliases. These
parameters will be appended to any which are specified for the module in
modules.options.

Add a remove method which will unload a given module from the kernel,
along with any modules it depended on, assuming those modules are now
unused.
Change-Id: Ie66dc153ef1771f50e26421d38d3656e95954780
Make the module name canonical in LoadWithAliases so it may be used
more easily from outside the class.

Modprobe functionality is required both within first stage init and also
as a standalone binary. Create a library for this using and extending
the logic in modalias_handler.cpp.
First stage init will attempt to load modules from /lib/modules.
