This changes the verification code in bootable/recovery to use
BoringSSL instead of mincrypt.
Cherry-pick of 452df6d99c81c4eeee3d2c7b2171901e8b7bc54a, with
merge conflict resolution, extra logging in verifier.cpp, and
an increase in the hash chunk size from 4KiB to 1MiB.

Migrate previous minzip to minzipold replacing the existing
minzipold. This will break compatibility with trees that do not
support selinux (ICS and older). Migrate former verifier files to
verifierold.
Add fuse.h to recovery source because older trees do not have it.
Add LOCAL_MODULE_TAGS where needed for 4.1 tree.

Kernel 2.6.16 is the first stable kernel with struct fuse_init_out
defined (fuse version 7.6). The structure is the same from 7.6 through
7.22. Beginning with 7.23, the structure increased in size and added
new parameters.
If the kernel only works on minor revs older than or equal to 22,
then use the older structure size since this code only uses the 7.22
version of the structure.

Split the adb-specific portions (fetching a block from the adb host
and closing the connections) out from the rest of the FUSE filesystem
code, so that we can reuse the fuse stuff for installing off sdcards
as well.

Implement a new method of sideloading over ADB that does not require
the entire package to be held in RAM (useful for low-RAM devices and
devices using block OTA where we'd rather have more RAM available for
binary patching).
We communicate with the host using a new adb service called
"sideload-host", which makes the host act as a server, sending us
different parts of the package file on request.
We create a FUSE filesystem that creates a virtual file
"/sideload/package.zip" that is backed by the ADB connection -- users
see a normal file, but when they read from the file we're actually
fetching the data from the adb host. This file is then passed to the
verification and installation systems like any other.
To prevent a malicious adb host implementation from serving different
data to the verification and installation phases of sideloading, the
FUSE filesystem verifies that the contents of the file don't change
between reads -- every time we fetch a block from the host we compare
its hash to the previous hash for that block (if it was read before)
and cause the read to fail if it changes.
One necessary change is that the minadbd started by recovery in
sideload mode no longer drops its root privileges (they're needed to
mount the FUSE filesystem). We rely on SELinux enforcement to
restrict the set of things that can be accessed.
