that isn't just std::atomic.
Also add a shared tgkill wrapper to libbase.

This change makes the internal UpdatePartitionTable function more
testable by parameterizing its write functions. It also adds two tests,
one of which exposes a flaw in the current implementation.

This change separates the WritePartitionTable function into two separate
functions: FlashPartitionTable and UpdatePartitionTable. This will be
cleaner than having extra unnecessary parameters and makes it clearer
when to call each one.
The motivation for this change is to improve the reliability of
UpdatePartitionTable() and to be able to simulate I/O failures for
testing.

escape_arg reuses the same index for the source (s) and the destination
(result), so it breaks on strings containing more than one quote, e.g:
* a'b'c ==> 'a'\''b'c'
* a'bcde'f ==> 'a'\''b'\'cde'f'
Also make the function more efficient by doing fewer string copies. This
code is based on the android::base::Split code.
Use EXPECT_EQ because the tests can keep going if one fails.

We shipped (well, are about to ship) an adbd that spuriously fails to
create directories upon push. Work around this in the adb client by
running a mkdir on all of the directories we would have otherwise
created.
On devices where we perform the workaround, this coincidentally fixes
a historic bug where we failed to push empty directories.

Block devices in the Linux kernel have a "minimum I/O request" size. The
minimum size is usually acquired by the block driver and can change
from device to device. When stacking devices (such as with
device-mapper), the kernel goes through great lengths to make sure this
alignment is respected for optimal I/O. In device-mapper's case,
misalignment can lead to kernel warnings and performance issues.
While this is unlikely to matter with a few targets, it could become
problematic on a large number of targets, and so we would prefer to
align all partition extents to the minimum I/O size.
We now support two new properties in the partition table geometry: an
"alignment", which is the minimum I/O size, and an "alignment offset",
which is an offset that when applied to sector 0, causes the sector to
be properly aligned within its parent device (for example, if a
physical partition is misaligned). All partition extents now begin on a
sector that respects this alignment.
One major caveat is that it is difficult for the initial partition table
to have the correct alignment without build system and/or flash tool
support. To accomodate this, all alignment is optional, and the lpmake
tool will support a default alignment of 1MiB as a failsafe.

When pushing to a path, we first try to ensure the directory path
exists and has the permissions expected by fs_config. Due to a change
that changed the fs_config check from a blacklist to a whitelist, we
started doing this for /data (which doesn't begin with /data/), and the
UID/GID for that path was accidentally being reused for following path
segments that didn't exist, leading to a failed attempt to chown
/data/local/tmp/foo to be owned by system.

1. init creates /mnt/product used to mount product-specific rw partitions.
2. If a device tree fstab entry for early mount specifies a mount point
under /mnt/product e.g. /mnt/product/foo, init will create
/mnt/product/foo mount point.

Test: change dt fstab entry to mount /mnt/product/foo; mount point is
created correctly, and partition is mounted in early mount.
