b81b99032d Documenting apex/builer.go
Mostly documentation changes, but includes a few refactorings like
changing the variable names, reordering functions, reordering statements
in logical order, etc.

cf371cc1f7 Replace android.WriteFile rule with android.WriteFileRule
The android.WriteFile rule takes careful escaping to produce the
right contents.  Wrap it in an android.WriteFileRule that handles
the escaping.

Test: compare all android.WriteFile outputs

03a7f3efed Don't remove entries for overriddable modules
Previously, when there is apex_set that is overriding another module,
the entry for the overridden module is removed from apexkeys.txt.
However, this is wrong because the existence of the apex_set module
doesn't necessary mean that the module is insatalled instead of the
overridden module. That is determined by PRODUCT_PACKAGES which Soong
has no knowledge of. Therefore, we don't delete the entry for the
overridden (actually possibly overridable) modules in the file.

8d6c51ebcc apex_sets is added to apexkeys.txt
apex_sets is a new module type that can be used to deliver pre-signed
APEXes, which previously could be done only via prebuilt_apex.

Soon gnow understands apex_sets module types and emits the signing info
of the modules to apexkeys.txt

fff3f8a3f8 Include partition tag in apexkeys.txt.
The partition tag helps merge_target_files.py determine
which apexkeys.txt to select from the framework partial
target files and which to select from the vendor partial
target files. The partition tag is the pysical partition
name, for example, a system_ext module on a device where
system_ext is at system/system_ext has a system
partition tag.

d1063c1586 Introduce module type 'sdk'
This change introduces a new module type named 'sdk'. It is a logical
group of prebuilt modules that together provide a context (e.g. APIs)
in which Mainline modules (such as APEXes) are built.

A prebuilt module (e.g. java_import) can join an sdk by adding it to the
sdk module as shown below:

sdk {
    name: "mysdk#20",
    java_libs: ["myjavalib_mysdk_20"],
}

java_import {
    name: "myjavalib_mysdk_20",
    srcs: ["myjavalib-v20.jar"],
    sdk_member_name: "myjavalib",
}

sdk {
    name: "mysdk#21",
    java_libs: ["myjavalib_mysdk_21"],
}

java_import {
    name: "myjavalib_mysdk_21",
    srcs: ["myjavalib-v21.jar"],
    sdk_member_name: "myjavalib",
}

java_library {
    name: "myjavalib",
    srcs: ["**/*/*.java"],
}

An APEX can specify the SDK(s) that it wants to build with via the new
'uses_sdks' property.

apex {
    name: "myapex",
    java_libs: ["libX", "libY"],
    uses_sdks: ["mysdk#20"],
}

With this, libX, libY, and their transitive dependencies are all built
with the version 20 of myjavalib (the first java_import module) instead
of the other one (which is for version 21) and java_library having the
same name (which is for ToT).

PRESIGNED.

This change also fixes a bug that non-installable APEXes are listed in
the file.

0ca3ce867c build apexkeys.txt
apexkeys.txt is a text file having APEX-to-keys mappings. The file is
included in the target-files package where it is used when re-sign the
APEXes with release keys.

Each line of the file consists of 5 fields:
1) name: file name of the APEX
2) public_key: the public key for the apex_payload.img of the APEX
3) private_key: the private key used to sign the apex_payload.img
4) container_certificate: the certificate used to sign the APEX zip
container
5) container_private_key: the private key used to sign the APEX zip
container

9335a26cbd APEXes can be signed with devkeys
When PRODUCT_DEFAULT_DEV_CERTIFICATE is set to /vendor/foo/devkeys/test,
then the public/private key pairs for an apex_key is searched at
/vendor/foo/devkeys directory.

To be specific,

/system/timezone/Android.bp:
apex_key {
    name: "timezone.key",
    public_key: "com.android.tzdata.avbpubkey",
    private_key: "com.android.tzdata.pem",
}

When PRODUCT_DEFAULT_DEV_CERTIFICATE isn't set, the keys are searched at
/system/timezone, which is the path where Android.bp is located.

With PRODUCT_DEFAULT_DEV_CERTIFICATE set to /vendor/foo/devkeys/test,
the keys are searched at /vendor/foo/devkeys.

Bug: 121224311

ff1458f670 APEX can be signed with different keys
A new module type 'apex_key' is defined to specify public and private
key pair for APEXs. An APEX can refer to the module via the property
'key'. When building the APEX, the private key from the key module is
used to sign it. In addition, the public key from the key module is
automatically installed to /system/etc/security/apex.
