This removes the custom ioctl code in fs_mgr_dm_linear.cpp in favor of
using libdm.

MinGW uses gnu_printf to force C99 printf analysis with GCC, but clang
does not support gnu_printf. So just use the default that's used for
other platforms. This also mirrors upstream commit
015e637b4b/.

Bug: http://b/91353691: std::chrono_utils is not available in the
libstdc++ in the mingw/gcc prebuilts. They can be used once we switch
to using libc++ for Windows host.

This change adds a LoopControl class for interacting with the loop
control device. In addition it provides a LoopDevice class for creating
temporary loop devices. This is aimed at being a building block for libdm
tests, so the current functionality is limited to attaching and
detaching file descriptors and finding free loop devices.

Before, I was using p_vaddr to get the offset into the elf file where
the exidx frame starts. I changed that to use p_offset since this already
has the load bias offset in it and some elf files do not set p_vaddr
properly.
Also, use p_filesz instead of p_memsz, since again, some elf files do
not set p_memsz to the same as p_filesz.
Bug: 110704153
Test: All libbacktrace/libunwindstack unit tests pass.
Test: Randomly unwind process on a walleye.
Test: Verified that this properly dumps and unwinds the shared
Test: library that sets p_vaddr and p_memsz differently.

This change implements the ability to get the path of a block device
given a device-mapper device name. In addition, dmctl now has a
"getpath" command to perform this query, as a shortcut for searching
through /sys/block/*/dm/name.

This functionality is useful for improving boottimes on the ARC++
project. Without this change, ro.serialno would be set to the empty
string when androidboot.serialno was unset in the kernel commandline.
Bug: 62039211
Test: boot with androidboot.serialno unset and ensure ro.serialno is
unset

These tests check that various aspects of liblp's on-disk management
are functioning as intended. This checks redundancy, metadata slot
management, and metadata update and readback.

This change implements DmTargetZero and DmTargetLinear, and integrates
them into dmctl. It also implements DmTarget and DmTable serialization.
Example dmctl invocation:
dmctl create my-device -ro \
linear 0 800 /dev/block/by-name/system 0 \
zero 800 1200 \
linear 1200 1500 /dev/block/by-name/system 1200

This change refactors DmTarget. It was satisfying two separate use cases
that have no overlap: (1) as a container for informational queries, and
(2) for specifying table targets.
The kernel's nomenclature for the former is a "target type," so the new
class is named DmTargetTypeInfo.
In addition, this change adds a unit test for
DeviceMapper::GetAvailableTargets that ensures the device has at least a
linear target type (with more TBD).
