Lukacs T. Berki b21166e236 Make symlink_forest.go prefer generated files.
Now, if the same file exists in the generated tree and the source tree,
it symlinks in the generated file instead of failing outright.

Drive-by fix: print errors for all conflicts instead of bailing out on
the first one.

Test: Presubmits (including the two new tests)

Lukacs T. Berki b353cca496 Create a synthetic Bazel workspace.
It's under out/soong/workspace and is a symlink forest that merges BUILD
files generated by bp2build and the source tree.

bazel-* symlinks and $OUTDIR are currently ignored.

Rupert Shuttleworth c143cc50dd Transform paths to headers in include dirs to take package boundaries into account.
This allows the following cc_library_static targets to build with bp2build:

- libc_freebsd
- libc_freebsd_large_stack
- libc_openbsd_ndk
- libc_gdtoa  (* but still fails for mixed builds)
- libc_aeabi
- libc_static_dispatch
- libc_dynamic_dispatch

This also allows a number of other cc_library_static targets to progress further in their builds.

Test: Added unit test

Jingwen Chen b4628eb03f bp2build: codegen singleton lists on one line.
This CL refactors the bp2build code generator to pretty print lists with
a single element on one line, instead of taking up three lines, which
can make BUILD files unnecessarily long. A single line singleton list is
also more commonly used in BUILD files.

Jingwen Chen 91220d7334 Add os/target configurable selects for label list attributes.
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": [],
        }),

Jingwen Chen 12b4c2706d bp2build: add allowlist for package-level conversions.
This CL adds the support for specifying lists of directories in
build/soong/android/bazel.go, which are then written into
out/soong/bp2build/MANIFEST. Using this configuration,
modules/directories can either default to bp2build_available: true or
false, while still retaining the ability to opt-in or out at the module level.

It also ensures that ConvertWithBp2Build returns true iff the module
type has a registered bp2build converter.

Jingwen Chen 5d8644990b bp2build: add configurable attribute (select) support.
This CL adds a basic framework to support configurable string_list
attributes, selecting on the Arch variant (x86, x86_64, arm, arm64).

It offers fine-grained controls to map individual configurable
properties (arch_variant) to configurable Bazel attributes, starting
with the string_list type for the copts property for cc_object.

This design is primarily motivated to have minimal boilerplate in
bp2build mutators, allowing anyone to opt-in configurable attributes,
and modify intermediate states before passing them on into the
CreateBazelTargetModule instantiator.

Jingwen Chen 8c1b97e01b bp2build: cc_object converter.
This CL introduces a basic bp2build converter for cc_object modules.
cc_objects maps cleanly to cc_library targets, but with -fnoaddrsig.

This CL also demonstrates generating include deps within a macro to
allow the cc_object compilation to depend on a relative-include header
within an include dir.

e.g. if "foo.cc" includes "android/log.h" and the latter is located at
"include/android/log.h", the autogenerated header deps would export
"android/log.h" correctly to the foo.cc upstream target.
