gsid is the only consumer for this library, and it's unlikely to grow
beyond gsid.

Also: remove an obsolete comment from linker_test.cpp. The test program is
at /data/nativetest[64]/libvndksupport-tests/libvndksupport-tests, which
may will be in the system or legacy configuration, and either the "sphal"
or "default" namespace will be visible.
Bug: none
Test: run libvndksupport-tests, device boots

clang-tidy hinted that some of this code wasn't right. Looking
deeper, there is really not much related to file and socket
descriptors, except that they're published in similar ways to the
environment. All of the abstraction into a 'Descriptor' class takes
us further away from specifying what we really mean.
This removes that abstraction, adds stricter checks and better errors
for parsing init scripts, reports sockets and files that are unable to
be acquired before exec, and updates the README.md for the passcred
option.
Test: build, logd (uses files and sockets) works

Some code only wants to use PageMap to determine whether pages are
mapped in to memory. Modify the code to optimize this path.
Changes:
- Add a function that doesn't read all of usage stats data for every
map. This operation is extremely expensive, and some code doesn't
care about it.
- Optimize the PageMap call to do a single read instead of a single
read per page.
- Add unit tests for these changes.

Test: Ran new unit tests.
Test: Ran procrank and verified data looks good.
Test: Ran DexDiag art tests.

Only thread group leaders should be registered with lmkd. Add a check to
ignore any non-leader TIDs and generate an error if such condition is
detected. Run the same check before killing a process to detect cases of
non-leader TIDs being used to kill a process. This might happen if PIDs
overflow and previously registered PID gets reused for a non-leader
thread in the following scenario:
1. pid X is a thread group leader and is registered with lmkd
2. pid X dies without lmkd knowing it and pid gets recycled
3. process Y creates a thread with tid X
4. lmkd kills pid X which results in process Y being killed

printWeakPointer isn't implemented anywhere. This also allows us to
remove a forward declaration of TextOutput.

This is no longer needed as CreateLogicalPartition() ensures the
obtained path will not race with device deletion.

This fixes a race condition where WaitForFile() after
GetDmDevicePathByName appears to succeed, but a subsequent operation on
the path fails. This can happen when CreateDevice() is called
immediately after a call to DeleteDevice (from any process), and the
path is re-used, enqueuing udev events to remove and re-add the block
device.
The fix for this is to introduce a new variant of CreateDevice() that
has a timeout parameter. When the timeout is positive, CreateDevice()
will wait for a /dev/block/mapper/by-uuid symlink to be created, which
signals that ueventd has finished processing the operation.
ueventd will now create these by-uuid symlinks for device-mapper nodes.
Unfortunately, the uuid is only available during "change" events, so we
have to special case device-mapper symlink creation. And since the uuid
is not available during "remove" events, we simply find matching links
to remove them.
This ensures that callers of CreateDevice() can use the device path
knowing that no asynchronous removals are pending. Code that uses the
old CreateDevice+WaitForFile pattern will be transitioned to the new
method.
Note that it is safe to ignore the timeout, or to use the "unsafe"
CreateDevice, if the caller ensures the path by other means. For example
first-stage init has no device removal, and regenerates uevents until
it has acquired all the paths it needs.
Finally, since libdm now inspects sysfs unconditionally, libdm consumers
need r_dir_file perms for sysfs_dm in their sepolicy. Additionally
linking to libdm now requires linking to libext2_uuid.
