This reverts commit ea4325baf8 to re-land
commit ef1bb4360f. It fixes the bug when
handling a package without care_map.txt (e.g. dm-verity not enabled).
In order to support streaming A/B OTA packages, we pack
payload_properties.txt and care_map.txt in ZIP_STORED mode. These two
entries along with payload.bin (already in ZIP_STORED prior to this CL)
can be fetched directly based on the offset and length info.
We write the offset and length info into the package metadata entry
(META-INF/com/android/metadata), which can be parsed by the OTA server.
payload_properties.txt and care_map.txt are usually less than 1-KiB. So
the change only incurs marginal size increase.

1.
fsconfig: fix fs_config_* build for discovered headers
When android_file system_config.h is picked up from the device
directory, neither TARGET_FS_CONFIG_GEN or TARGET_ANDROID_FILESYSTEM_CONFIG_H
are specified. Thus, the build is not generating the required fs_config_files
and fs_config_dirs.
Test: Ensure that make fs_config_files works, and produces the same output as before
Build the system image and mount it as a loop back and dump the file system
capabilities with getcap. Verify that output to the supplied
android_file system_config.h
From the loopback of the system.img mount, from CWD system/bin:
$ getcap *
cnss-daemon = cap_net_bind_service+ep
hostapd = cap_net_admin,cap_net_raw+ep
imsdatadaemon = cap_net_bind_service+ep
ims_rtp_daemon = cap_net_bind_service+ep
logd = cap_setgid,cap_audit_control,cap_syslog+ep
mm-qcamera-daemon = cap_sys_nice+ep
pm-service = cap_net_bind_service+ep

surfaceflinger = cap_sys_nice+ep
webview_zygote32 = cap_setgid,cap_setuid,cap_setpcap+ep
webview_zygote64 = cap_setgid,cap_setuid,cap_setpcap+ep
Compared to the android_filesystem_config.h:

We compute the max stashed_blocks in ReviseStashSize(), prior to calling
WriteTransfers(), to avoid running out of space due to stashing.
There is a bug when computing the to-be-freed stashed blocks, where we
wrongly free the space _before_ executing the transfer command. This leads
to a script failure where the max stash size violates the max allowed
size in WriteTransfers().
Note that this bug doesn't affect already generated packages. It's only
an underestimate in ReviseStashSize(). The check in WriteTransfers() has
been correct to ensure the max stash size.

Prior to this change, when signing APKs, the build system invoked
'aapt dump badging' on each APK, to detect the value to pass into
signapk as --min-sdk-version. Now that signapk uses the apksig
library, it can auto-detect that value on its own, thus avoiding the
need to invoke 'aapt dump badging' and thus speeding up the build
process.
The semantics of signapk's --min-sdk-version flag is changed by this
commit from having the default value of 0 to having the default value
of "auto-detect from APK".
P.S. The get-package-min-sdk-version-int is not removed from
core/definitions.mk in this commnit, because this function is used in
another project's .mk file and thus that .mk file needs to be modified
first.

(cherry picked from commit b59eca3586)
In two-step OTAs, we write recovery image to /boot as the first step so
that we can reboot from there and install a new recovery image to
/recovery. However, bootloader will show "Your device is corrupt"
message when booting /boot with the recovery image. Because the recovery
image encodes the path of "/recovery" as part of the signature metadata,
which fails the verified boot.
This CL generates a special "recovery-two-step.img" in addition to the
regular recovery.img. This image encodes "/boot" when being signed,
which will be flashed to /boot at stage 1/3 in a two-step OTA.
Here are the desired changes:
- 'IMAGES/recovery-two-step.img' exists in target_files.zip for non-A/B
targets (e.g. bullhead). The image should not exist for targets that
don't have a recovery partition (e.g. A/B devices like sailfish).
- <device>-img.zip should not contain 'recovery-two-step.img'.
- Nothing should change when building non-two-step OTAs. For two-step
OTAs, 'recovery-two-step.img' should be included in the OTA package;
'updater-script' should flash this image to /boot at stage 1/3.
- When building a two-step OTA with an input TF.zip that doesn't have
IMAGES/recovery-two-step.img, it should use the existing
IMAGES/recovery.img instead.
Bug: 32986477
Test: Tested the steps above on bullhead and sailfish.

When configuring fs_config_files or fs_config_dirs for file_system
capabilities, drop the requirement that OEMs must add the target
to PRODUCT_PACKAGES. This limits the configuration requirement
to only needing to set the new and preferred TARGET_FS_CONFIG_GEN
or the older TARGET_ANDROID_FILESYSTEM_CONFIG_H method.
Test: That only setting TARGET_FS_CONFIG_GEN results in passwd and
group in the build image.

Succinctly, the output is a colon delimited string containing the following
fields:

* encrypted password (optional)
* gid (int)
* userlist (str,...)
Multiple colon delimited lines may exist, but will not be separated
across lines.

Introduce a generator that outputs passwd files per man(5) passwd.
Succinctly, the output is a colon delimited string containing the following
fields:
* login name
* encrypted password (optional)
* uid (int)
* gid (int)
* User name or comment field
* home directory
* interpreter (optional)
Multiple colon delimited lines may exist, but will not be separated
across lines.
When run, produces:
foo::2900:2900::/:/system/bin/sh
foo_bar::2901:2901::/:/system/bin/sh
custom_oem1::2902:2902::/:/system/bin/sh
Note that this generator allows for 0 or more config.fs files. This allows for:
* Unconditional inclusion of /system/etc/passwd in the generated image
* A blank passwd file if no config.fs files are specified.
This ensures that when OEMs add config.fs files, there is no additional steps
for proper functionality (simpler for OEMs).
The one draw back is the additional inode consumption on system for a possible
blank file.
Test: That it produces a valid passwd file.
