`m <sdk_name>` generates two scripts each of which is use to update the
current snapshot of the SDK and to freeze ToT as a new version,
respectively. Executing the scripts will copy necessary files (stub
libraries, AIDL files, etc.) along with Android.bp into the ./<apiver>
directory under the directory where the sdk is defined.
This change also introduces a new module type 'sdk_snapshot' that
represents a snapshot of an SDK. It will be auto-generated by the above
scripts, so developers are not expected to write this manually.
The module type 'sdk' is now used to simply specify the list of modules
that an SDK has.
Finally, this change changes the version separator from '#' to '@'
because '#' confuses Make.

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).
