Currently, the order that we kill to services during shutdown is the
order of services_ in ServiceManager and that is defacto the order in
which they were parsed, which is not a very useful ordering.
Related to this, we have seen a few issues during shutdown that may be
related to services with dependencies on other services, where the
dependency is killed first and the dependent service then misbehaves.
This change allows services to keep track of the order in which they
were started and shutdown then uses that information to kill running
services in the opposite order that they were started.

and rotate it after reboot instead.

The use of ReadAtOffset is meant to allow concurrent access
to the zip archive once it has been loaded. There were places
where this was the case, and some places that did a seek + read
combination, which could lead to data races.
NOTE: On Windows, we are not using pread as the implementation of
ReadAtOffset, therefore the guarantees on Windows are weaker.
On Linux, pread allows the file descriptor to be read at a specific
offset without changing the read pointer. This allows inherited fd's
and duped fds to be read concurrently.
On Windows, we use the ReadFile API, which allows for an atomic seek +
read operation, but modifies the read pointer. This means that any mix
use of ReadAtOffset and Read will have races. Just using ReadAtOffset is
safe.
For the Windows case, this is fine as the libziparchive code now only
uses ReadAtOffset.

Setting androidboot.seccomp=global on the kernel command line shall
enable seccomp for all processes rather than just in zygote. Doing
this has a performance impact, for now it shall just be used to audit
syscall usage during testing.

Because full disk encryption make surper block is not except contents. Only
judge the magic number can prevent most of encrypted surper block.
In particular, magic number plaintext may be equal ciphertext. In order to
avoid this situation, we add the judgment of adaptive situation of the
s_rev_level, s_log_block_size and EXT4_INODE_SIZE.
Test: 1. Config fstab,userdata add flags: forceencrypt=footer,reservedsize=128M
2. build a new target files, and flash all image.
3. Config encrypt userdata surperblock,set magic number is 0xEF53
4. reboot system and check log of fs_mgr.
