be763f7b16 Skip default dependencies for header libraries
Header libraries don't compile anything, so they don't need the
default stl and libclang_rt dependencies.  Trimming the dependencies
simplifies using header libraries for LLNDK libraries, which need
extra variants that don't exist for the default dependencies.

1a2462717e Replace stringly-typed API levels.
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.

82e192c3ae Add sdk mutator for native modules
Compiling native modules against the NDK disables platform features
like ASAN.  For anything shipped on the system image there is no
reason to compile against the NDK.  Add a new mutator to Soong that
creates a platform and an SDK variant for modules that set
sdk_version, and ignore sdk_version for the platform variant.  The
SDK variant will be used for embedding in APKs that may be installed
on older platforms.  Apexes use their own variants that enforce
backwards compatibility.

b8eefa8956 Do not explicitly link ucrt, ucrtbase
This was required before MinGW's default crt was set to ucrt.  In the
new setting, libmsvcrt.a is similar to libucrt.a and is implicitly
linked-in by the Clang driver.  Not explicitly linking in ucrt avoids
the link-order issue discussed in
https://github.com/android/ndk/issues/1198.

e5ba28648f build: Link the unwinder dynamically into platform and vendor binaries.
Instead of linking the unwinder statically into every binary, link it
dynamically, by exporting the symbols from libc.so. This has a number
of advantages:

- Reduces image size (system.img size decreases by 1.7MB on walleye-userdebug,
  and 1.2MB on crosshatch-userdebug).
- Allows us to easily change/upgrade the unwinder throughout the system,
  including vendor prebuilts.
- Allows code outside of libc++ to define custom personality routines.
  Previously, personality routines would call the unwinder routines in the
  local binary, which would cause problems with unwinders with global state
  (such as the libgcc unwinder) if the copy of the unwinder used for unwinding
  (normally libc++'s copy) were different from the copy linked against the
  personality routine.

4af21ed26f Split local and global cflags
Native compiler flags are currently applied in approximately:
global cflags
local cflags
local include dirs
global include dirs
global conlyflags
local conlyflags
global cppflags
local cppflags

This means that a flag that is enabled in the global cppflags
cannot be disabled in the local cflags, and an Android.bp author
must know to disable it in the local cppflags.  A better order
would be:
global cflags
global conlyflags
global cppflags
local cflags
local conlyflags
local cppflags
local include dirs
global include dirs

We are mixing both the global and local cflags into a single
variable, and similar for conlyflags and cppflags, which
prevents reordering them.  This CL prepares to reorder them
by splitting the global and local cflags into separate variables.

52767be335 Add support for Rust C libraries.
Adds the ability for rust modules to be compiled as C libraries, and
allows cc modules to depend on these rust-generated modules. This also
means that soong-rust should not have any dependencies on soong-cc aside
from what's required for testing.

There's a couple small fixes included as well:

 - A bug in libNameFromFilePath that caused issues when library's had
 "lib" in their name.
 - VariantName is removed from rust library MutatedProperties since this
 was unused.

b49fe1bde7 Stop linking libdl.a into static bins
libdl.a has a no-op dlopen, which breaks static libraries that need a real
dlopen. Instead of automatically linking libdl.a into static executables,
make it optional.

Until recently, the libunwind_llvm.a unwinder, used on arm32, needed the
no-op dladdr, but it's now built using -D_LIBUNWIND_USE_DLADDR=0.

The HWASan run-time uses dlsym and dladdr, so add a libdl dependency for
HWASan-built static binaries. We could also remove the dependency from
libclang_rt.hwasan_static-*.a, but this is also easy to do.

Bug: http://b/141485154
Test: bionic unit tests, device boots, verify that static and dynamic
   executables can throw/catch an exception
Test: verify that a static executable using dlopen doesn't link (unless it

f7a17daefe Use -nostdlib++ instead of -nodefaultlibs
Host builds using libc++ used -nodefaultlibs to turn off the default
C++ runtime, and then added back all the other necessary libraries.
Clang supports -nostdlib++ since https://reviews.llvm.org/D47115
that removes the C++ runtime without affecting the other default
libraries.  Use -nostdlib++, and remove the lists of default
libraries.

99f2fc27e6 BoringSSL FIPS build - introduce extraLibFlags and use for STL libs.
Rationale: On non-bionic, stl.go currently adds system libraries to
ldFlags, this causes problems for partialLd rules.  However adding the
same libraries to libFlags breaks some existing modules due to symbol
conflicts as the system libraries are linked before some module code.

Introduced a general mechanism for adding libraries to be linked
last rather than making this STL-specific.

a403cc7254 Change STL for Windows to libc++.
- Stop including libstdc++ headers.
- '-pthread' and 'static-libgcc' are unused when we pass -nodefaultlibs.
We didn't pass -nodefaultlibs for libstdc++.
- Use SjLj exceptions for 32-bit.  libgcc_eh implements SjLj exception
model for 32-bit.
- Disable visibility annotations for libcxx and libcxxabi since we are
only going to support these as static libraries.
- Use Win32 threads.  MinGW pthreads throws an error when building
libcxx since it's pthread_mutex_initializer is not constant (needs a
cast).
- Link libgcc_eh, which needs pthread, which in turn depends on
kernel32.  Wrap the libraries with --start-group and --end-group and
remove duplicates.

 * The existing STL-dependency logic in linkShared only applies to shared

   both shared libraries and executables.

 * Remove the ndk_prebuilt_library/ndkPrebuiltLibraryFactory module type,

libc++'s headers are annotated with availability macros that indicate
which version of Mac OS was the first to ship with a libc++ feature
available in its *system's* libc++.dylib. We do not use the system's
library, but rather ship our own. As such, these availability
attributes are meaningless for us but cause build breaks when we try
to use code that would not be available in the system's dylib.

27991b7652 Add -lm to the default libs for Linux & Darwin
libm is a default library for device builds, so default it for host
builds as well.

Also removes duplicate additions of -ldl, -lpthread, -lm and -lrt.

Test: m host

ef88ae2369 Make libdl.so be loaded after libc.so
Make sure that libdl is always after libc on the command line.
Simplifies the logic to always support system_shared_libs for
sdk and vndk builds.

For backwards compatibility without updating lots of Android.bp
files, allow libdl to be listed in shared_libs as long as it
is also in system_shared_libs or libc is not in system_shared_libs.

Remove all the places that libdl is added as a dependency, since
it will always be present unless explicitly removed now.

87f9f03d3f Add libc++ and libc++_static aliases for SDK builds.
c++_shared and c++_static are named libc++ and libc++_static in every
other mode. Allow the same names so targets which are built for both
host and device with SDK may specify a single name for the STL.

Test: external/boringssl is able to use "libc++_static" as the STL.
