init and vold also need to write bootloader message, so
split this function from uncrypt into a separate library.

We used to rely on files (e.g. /cache/recovery/command and
/cache/recovery/uncrypt_status) to communicate between uncrypt and its
caller (i.e. system_server). Since A/B devices may not have /cache
partitions anymore, we switch to socket communication instead.
We will keep the use of /cache/recovery/uncrypt_file to indicate the OTA
package to be uncrypt'd though. Because there is existing logic in
ShutdownThread.java that depends on the existence of the file to
detect pending uncrypt works. This part won't affect A/B devices without
/cache partitions, because such devices won't need uncrypt service (i.e
the real de-encrypt work) anyway.

The framework CL in [1] removes the use of "pre-recovery" service which
is basically to trigger a reboot into the recovery.

Writing map file directly can break consistency in map file if
it fails in the middle. Instead, we write a temporary file and
rename the temporary file to map file.

The `std::string package` variable goes out of scope but the input_path
variable is then used to access the memory as it's set to `c_str()`.
This was detected via OpenBSD malloc's junk filling feature.

We have the following warnings when compiling uncrypt on LP64 (e.g.
aosp_angler-userdebug).

According to POSIX spec [1], we have:
off_t and blksize_t shall be signed integer types;
size_t shall be an unsigned integer type;
blksize_t and size_t are no greater than the width of type long.
And on Android, we always have a 64-bit st_size from stat(2)
(//bionic/libc/include/sys/stat.h).
Fix the type and add necessary casts to suppress the warnings.

It turns out the standard explicitly states that if the pointer is
null, the deleter function won't be called. So it doesn't matter that
fclose(3) doesn't accept null.

This patch removes costly O_SYNC flag for encrypted block device.
After writing whole decrypted blocks, fsync should guarantee their consistency
from further power failures.
This patch reduces the elapsed time significantly consumed by upgrading packages
on an encrypted partition, so that it could avoid another time-out failures too.

Clean up leaky file descriptors in uncrypt/uncrypt.cpp. Add unique_fd

When it reboots into recovery for a factory reset, it still needs to
write the uncrypt status (-1) to the pipe.

uncrypt needs to be triggered to prepare the OTA package before
rebooting into the recovery. Separate uncrypt into two modes. In
mode 1, it uncrypts the OTA package, but will not reboot the
device. In mode 2, it wipes the /misc partition and reboots.
Needs matching changes in frameworks/base, system/core and
external/sepolicy to work properly.
