83fdc99960 Add a fuzzer for gptfdisk. 
Since gptfdisk is used to parse MBR and GPT partition tables from
untrusted USB and SD card storage devices, we should get a fuzzer
wired up to hunt for security issues.

To enable the fuzzer, we create a new "diskio-heap" implementation
for backing I/O operations, which allows us to treat the fuzzer
input as a fake block device.  These changes are as minimal as
possible to avoid future merge conflicts.

The single corpus input is a sample block device with a single
empty GPT partition created using these commands:

$ losetup /dev/loop0 typical.bin
$ gdisk /dev/loop0

And the final table is:

Number  Start (sector)    End (sector)  Size       Code  Name
   1              34              38   2.5 KiB     8300  Linux filesystem

caedc3271d ANDROID: Fix heap overflow in sgdisk 
If a maliciously formatted USB or SD Card device was inserted into an
Android device, the sgdisk tool could crash. This crash occurs because
sgdisk does not validate that the number of GPT partition entries
specified on disk matches the internal maximum permitted by the GPT spec.

Fix this by sanity checking the on disk parameter before using it.

After the fix, sgdisk detects the corrupt GPT during the formatting
procedure, but it is harmlessly zapped and replaced with a new one.

Test: before fix, saw sgdisk crash while the device was booting up
Test: after fix, no more sgdisk crashes
Test: went through "portable storage" and "adopted storage" wizard flows
      using the cuttlefish virtual device and a malicious partition
      table flashed to the device
