The uevent.partition_num easily collides between partitions, for
example:
Both /dev/block/sda3 and /dev/block/sdd3 will generate the same symlink:
/dev/block/platform/soc/1da4000.ufshc/by-num/p3
This change remove those by-num symlinks as there seems no effective
user of it.

This change splits out the selinux initialization and supporting
functionality into selinux.cpp and splits the security related
initialization of the rng, etc to security.cpp. It also provides
additional documentation for SEPolicy loading as this has been
requested by some teams.
It additionally cleans up sehandle and sehandle_prop. The former is
static within selinux.cpp and new wrapper functions are created around
selabel_lookup*() to better serve the users. The latter is moved to
property_service.cpp as it is isolated to that file for its usage.

While refactoring ueventd, I was looking for code the character device
symlinks (/dev/usb/*) that ueventd creates, such that I could test it
on a real device. I found none in our tree, and history showing Xoom,
which was last supported years ago, was the last user. If this code
is in fact obsolete, let's remove it.

In order to create symlinks for USB and block devices, the path for
their parent platform device must be known.
Previously, ueventd would save each platform device that it encounters
to a list and query this list when creating the symlinks. That,
however, is racy because the uevent socket does not differentiate
uevents from RegenerateUevents() and uevents sent by the kernel when
probing a device first the first time. The below scenario is the
faulty case:
1) Kernel probes parent platform device for a block device
2) ueventd calls RegenerateUevents() and starts processing uevents
3) Kernel probes block device and sends its uevents
4) ueventd picks up the block device uevent during its uevent processing,
without yet regenerating the platform device uevent, causing improper
symlinks to be created.
This change stops storing the platform devices in a list, and instead
traverses up the directory structure for each USB or block device
until it reaches a platform device, defined as one whose subsystem is
the platform bus. This fixes the race and simplifies the ueventd
code.

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

Create classes for dev and sys permissions and store these permissions
in std::vector instead of the C list.

Also simplify this code a bit.
There's only one consumer that removes the /devices/platform prefix,
so have them handle it instead of storing two copies of the string.
Remove an unneeded search for '/' in get_character_device_symlinks()
as a / will always be the next character after a parent path, by
nature of FindPlatformDevice().
