We call uncrypt services to setup / clear bootloader control block (BCB)
for scheduling tasks under recovery (applying OTAs, performing FDR).
However, we cannot start multiple requests simultaneously. Because they
all use the same socket (/dev/socket/uncrypt) for communication and init
deletes the socket on service exits.
This CL fixes the issue by a) adding synchronized blocks for the service
requests; b) checking the availability of the socket before initiating a
new one.
Note that adding synchronized blocks to RecoverySystem doesn't help,
because the calls could be made from different processes (e.g. priv-app,
system_server).
Bug: 31526152
Test: FDR works while a priv-app keeps calling clear BCB.

This introduces a new feature of the IBinder command protocol
to allow the shell command implementation to call back into
its caller to ask it to open files in the calling context. This
is needed so that commands that have arguments specifying files
can open those files as the calling shell, not the system (or
whatever) process.
To test this all out, move the "am start" implementation over
to ActivityManagerShellCommand, in particular along with its
option to specify a file in which to write profiling data.
Test: Manual

This will enable the developers to check if they could replace an unbuffered
I/O operation with a corresponding buffered I/O operation.
The policy can be set as follow:
StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder()
.detectUnbufferedIO().build());

(cherry picked from commit 9b7184a8fd)w
Log the error code to uncrypt_status if uncrypt gets killed because
of timeout.
Test: We log the error code correctly in uncrypt_status when uncrypt timeouts.

SystemProperties.get() is not particularly fast,
especially if a string is returned. Since ro.* values
are unable to be changed, there's no need to
continously re-query them. Cache the value at
static init time to trivially fix this.
Test: refactoring CL.

When we create a file that already exists, we try attaching a suffix
like "(1)" to the filename to avoid the conflict. The newly added
rename method should do the same, since developers may not have
access to delete the conflicting file.
Test: boots, rename via UI, new unit tests
