ed506f7356 ueventd: Break devices.cpp into discrete classes
devices.cpp handles too many things for creating one class.  This
change breaks it up into various files and classes.

* Parsing is moved to ueventd_parser.cpp
* Reading from the uevent socket and Cold booting is moved to a
  UeventListener class, in uevent_listener.cpp
* Firmware handling is moved to firmware_handler.cpp
* The remaining contents form a DeviceHandler class within devices.cpp

14fc01301d init: start move to Android.bp
Move libinit, init_tests, and test_service to Android.bp
Leave init in Android.mk as it has unfulfilled dependencies, but
create a comment in Android.bp for future use.
Remove libinit_parser and init_parser_tests as that code was never
used in init.

20651f62d0 first stage mount: removing the requirement of by-name prefix for AVB
Current first stage mount for AVB requires specifying a common prefix of
by-name symlink for all AVB partitions. It limits all AVB partitions to be on
the same block device.

firmware {
    android {
        compatible = "android,firmware";
        vbmeta {
            compatible = "android,vbmeta";
            parts = "vbmeta,boot,system,vendor";
            by_name_prefix="/dev/block/platform/soc.0/f9824900.sdhci/by-name"  <-- *removing this*
        };
        fstab {
            compatible = "android,fstab";
            vendor {
                compatible = "android,vendor";
                dev = "/dev/block/platform/soc.0/f9824900.sdhci/by-name/vendor";
                type = "ext4";
                mnt_flags = "ro,barrier=1,inode_readahead_blks=8";
                fsmgr_flags = "wait,avb";
            };
        };
    };
};

For normal mount with AVB, it extracts the by-name prefix of /misc
partition and use it as the prefix for all other partitions:
    - /dev/block/platform/soc.0/f9824900.sdhci/by-name/misc ->
    - /dev/block/platform/soc.0/f9824900.sdhci/by-name/vendor_a

Fix this by adding an internal map in FsManagerAvbOps to record the mapping
from partition name to its by-name symlink:

    ByNameSymlinkMap["vendor_a"] = "/dev/block/platform/soc.0/f9824900.sdhci/by-name/vendor_a"

Two overloaded factory methods are then provided for FsManagerAvbUniquePtr:
    - FsManagerAvbUniquePtr Open(ByNameSymlinkMap&& by_name_symlink_map):
      for first stage mount, where the by-name symlink map will be
      constructed externally, from the uevents processed by init, before
      invoking this factory method.

    - FsManagerAvbUniquePtr Open(const fstab& fstab): for normal mount,
      where the by-name symlink map will be constructed from the input fstab
      internally.

482f36cf74 init: remove restorecon() from util.cpp
restorecon() has become nothing more than a small wrapper around
selinux_android_restore().  This itself isn't super problematic, but
it is an obstacle for compiling util.cpp on the host as that function
is not available on the host.

33838b1156 init: change kill order and fix error reporting in KillProcessGroup()
First kill the process group before killing the cgroup to catch
the hopeful case that killing the cgroup becomes a no-op as all of its
processes have already been killed.

Do not report an error if kill fails due to ESRCH, as this happens
often when reaping processes due to the order in which we call
waitpid() and kill().

Do not call killProcessGroup in libprocessgroup if we have already
successfully killed and removed a process group.

5a86cb7694 init: use do_exec() for init_user0
Similar to what installkey used to do, init_user0 forks and
synchronously waits for vdc to return.  This is dangerous to do in
init however as init also processes properties from a single thread.

I'm not aware of any specific issues that this is currently causing,
but it's a good preventative measure to match what installkey does and
use do_exec().

Test: Boot bullhead, see that init_user0 still happens

ea5fca4cd0 init: fix first stage mount failure due to /dev/device-mapper not found
It has been reported that fs_mgr failed to open /dev/device-mapper
during the first stage mount. It's because other uevent (e.g., i2c
charger device) happens to be sent at the same time we're triggering
the device-mapper uevent to be sent. Current implementation returns
COLDBOOT_STOP unconditionally so it will only process the first received
uevent, leaving device-mapper uevent unhandled when the race happens.

Fix this by only returning COLDBOOT_STOP when the received uevent->path
matches that of device mapper.

e7656b7200 ueventd: do not reference init's sehandle
Init exposes a global 'sehandle' that ueventd references as part of
devices.cpp and util.cpp.  This is particularly dangerous in
device_init() in which both uevent and init write to this global.

This change creates a separate local copy for devices.cpp and puts
restrictions on where init.h can be included to make sure the global
used by init is not reference by non-init code.  Future changes to
init should remove this global.
