ReadFstabFromFp() have two callers right now, ReadFstabFromFile() and
ReadFstabFromDt(). ReadFstabFromFile() opens a FILE* and pass it to
ReadFstabFromFp(), and ReadFstabFromDt() wraps a std::string::c_str()
buffer in a FILE* adaptor with fmemopen().
There's no need for such adaptor, just change ReadFstabFromFp() to
accept std::string and we're good.

class_restart accidentally restarts disabled services. Changing this
behavior is risky as it could break compatibility. Instead, add an
"--only-enabled" argument to class_restart to opt-in to the new
functionality. This syntax is backward compatible, as previously only a
1-argument form was accepted.

Unfortunately, some recovery fstabs still specify the FDE options, where
they never really did anything anyway. Allow them for now, since it
seems preferable to restrict any breakage to the case that really
matters (devices actually configured to use FDE in their main fstab).

There are some fstab files that specify "encryptable=footer" for
adoptable storage volumes, which contradicts the documentation which
says that it should be "encryptable=userdata". However, the argument
was previously being ignored anyway. To avoid unnecessarily breaking
such devices, ignore the argument to "encryptable".
Note that we continue to only allow "encryptable" in combination with
"voldmanaged". So, fstabs that use "encryptable" for FDE (rather than
for adoptable storage) should continue to be rejected.

android::base::Tokenize() is like android::base::Split() but ignores
empty tokens. Think strtok_r() and strsep().
C++-ify parsing code by replacing strtok_r() with Tokenize(), which
results in more concise and readable code.

- Use "likelihood" instead of "probability" since that has connotations
of being less precise, and our probability ordering isn't very precise
anyway.
- Hide the fault address with SEGV_MTEAERR because it is not available.
- Pad the fault address with leading zeroes to make it clearer which
bits of the top byte (and any following bytes such as PAC signature
bits) are set.

Remove the class_start_post_data and class_reset_post_data commands,
since they aren't used anymore. They were only used on devices that
used FDE (Full Disk Encryption), via actions in rootdir/init.rc. These
actions have been removed, since support for FDE has been removed.
There is no use case for these commands in vendor init scripts either.
Keep the mark_post_data command, since DoUserspaceReboot() uses the
post-data service flag even on non-FDE devices.

Since Android 10, new devices have been required to use FBE instead of
FDE. Therefore, the FDE code is no longer needed.

Since Android 10, new devices have been required to use FBE instead of
FDE. Therefore, the FDE code is no longer needed.
Make fs_mgr reject fstabs where FDE is enabled.
Unfortunately, there is a quirk where the "encryptable" flag (which was
originally meant just for FDE) was overloaded to identify adoptable
storage volumes. It appears that we have to keep supporting this use
case. Therefore, don't reject the "encryptable" flag completely.
Instead, just reject "encryptable" when it appears without
"voldmanaged", or without "userdata" as its argument.
Here are some references for how "encryptable=userdata" is being used to
identify adoptable storage volumes:

"nonplat" was renamed to "vendor" in Android Pie, but was retained
here for Treble compatibility.
We're now outside of the compatbility window for these devices so
it can safely be removed.
While I'm here, improve accuracy of some comments and
in-code-documentation.
Test: build boot cuttlefish device. adb remount, modify
/system/etc/selinux/plat_sepolicy_and_mapping.sha256 to force
on-device policy compilation. reboot. Verify that device boots
without new selinux denials.

Direct writes for partition flashing significantly increase performance.
Use O_DIRECT flag when opening partition for flashing. Additionally use
a 4096b aligned buffer which is required for O_DIRECT.
Switch from using 8MB write buffer to 1MB write buffer, as the extra
allocation has no performance impact.
