This CL is pretty large, so I recommend starting with reading the newly
added tests for the expected behavior.
This change works in conjunction with the linked CLs in the Gerrit topic.
Those CLs add support for new platform() definitions for OS targets
specified in Soong's arch.go, which are configurable through
Android.bp's `target {}` property. It works similary to previous CLs
adding support for the `arch {}` property.
These configurable props are keyed by the OS: android, linux_bionic,
windows, and so on. They map to `select` statements in label list
attributes, which this CL enables for cc_library_headers' header_libs
and export_header_lib_headers props.
This enables //bionic/libc:libc_headers to be generated correctly, from:
cc_library_headers {
name: "libc_headers",
target: {
android: {
header_libs: ["libc_headers_arch"],
export_header_lib_headers: ["libc_headers_arch"],
},
linux_bionic: {
header_libs: ["libc_headers_arch"],
export_header_lib_headers: ["libc_headers_arch"],
},
},
// omitted props
}
to:
cc_library_headers(
name = "libc_headers",
deps = [] + select({
"//build/bazel/platforms/os:android": [
":libc_headers_arch",
],
"//build/bazel/platforms/os:linux_bionic": [
":libc_headers_arch",
],
"//conditions:default": [],
}),
)
Test: TH
Test: Verify generated //bionic/libc:libc_headers

Also refactor bp2build-related code for cc_library_headers.
(Retry of previous CL after the presubmit failed to detect a merge conflict)
Test: Added unit test.
Test: bp2build-sync.py write; bazel build //bionic/... still works (but bp2build is disabled for most cc_library_static targets for other reasons)

Move the vendor snapshot tests into vendor_snapshot_test.go to
reduce the size of cc_test.go
Bug: 177098205
Test: go test ./build/soong/cc/...

Also some files are refactored:
- snapshot_prebuilt.go is separated from vendor_snapshot.go. Now
vendor_snapshot.go contains snapshot generation codes, while
snapshot_prebuilt.go contains module definition codes.
- Some helper functions are moved from snapshot_utils.go to util.go.
- Some ambiguous names of types and functions are renamed.
We still can add more detailed comments about the snapshots. They are to
be uploaded in follow-up changes, to avoid making this change too big.

List of stub libraries from system (and bionic APEX) is currently
managed in static file. This change generates the list at build time and
adds to the system config so linkerconfig can use it.
Bug: 172889962
Test: Build cuttlefish and confirmed list is generated in
/system/etc/linker.config.pb

Handling of API levels within Soong is currently fairly difficult
since it isn't always clear based on context what kind of API level a
given string represents, how much canonicalizing and error checking
the code receiving the string are expected to do, or how those errors
should be treated.
The API level struct does not export its raw data, so as to keep its
"constructor" private to the android package, and to prevent misuse of
the `number` field, which is only an implementation detail for preview
API levels. API levels can be parsed with either
`android.ApiLevelFromUser`, which returns any errors to the caller, or
`android.ApiLevelOrPanic`, which is used in the case where the input
is trusted and any errors in parsing should panic. Even within the
`android` package, these APIs should be preferred over direct
construction.
For cases where there are context specific parsing requirements, such
as handling the "minimum" alias in the cc module,
`nativeApiLevelFromUser` and `nativeApiLevelOrPanic` should be used
instead.
