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.
Bug: none

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 security.perf_harden is disabled through adb, use some debug
system properties to set profiling limits in the kernel, including
cpu percentage, memory, and max sample rate.

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.
