869a0faf21 Add "product_available" to product available modules
"vendor_available" modules were available to product modules.
However, not all "vendor_available" modules are required to be
available to product modules. Some modules want to be available only
to product modules but not vendor modules.

To cover the requirement, we separate "product_available" from
"vendor_available".
"vendor_available" will not provide product available module.

8393a8bc84 Make the connection between implementation and llndk_library explicit
Instead of assuming a module with the .llndk suffix exists, add an
llndk_stubs property to every cc_library module that has a
corresponding llndk_library.  Also rename the llndk_library to have
an explicit .llndk suffix.

0cdf132f84 Expose per-process memory init.
In order to disable memory initialization for a process, the following
command can be used:

    android_mallopt(M_DISABLE_MEMORY_MITIGATIONS, nullptr, 0);

Since this is needed in vendor processes, this is exposing this
functionality to llndk. For convenience (and adding standard logging),
a helper function is being added into libcutils in order to use this,
w/o having to get into so many details.

5d3aa86cd1 Add an API for per-process disabling memory initialization.
Introduce an android_mallopt(M_DISABLE_MEMORY_MITIGATIONS) API call
that may be used to disable zero- or pattern-init on non-MTE hardware,
or memory tagging on MTE hardware. The intent is that this function
may be called at any time, including when there are multiple threads
running.

Disabling zero- or pattern-init is quite trivial, we just need to set
a global variable to 0 via a Scudo API call (although there will be
some separate work required on the Scudo side to make this operation
thread-safe).

It is a bit more tricky to disable MTE across a process, because
the kernel does not provide an API for disabling tag checking in all
threads in a process, only per-thread. We need to send a signal to each
of the process's threads with a handler that issues the required prctl
call, and lock thread creation for the duration of the API call to
avoid races between thread enumeration and calls to pthread_create().

379ed1ef62 Explicitly add the include path for android_filesystem_config.h
android_filesystem_config.h is found since system/core/include is on
the include path for all projects and contains a symlink to the real
android_filesystem_config.h.  This is fragile and the below bug seeks
to remove this symlink and have users correctly depend on
libcutils_headers.

In bionic, libcutils_headers header library cannot be used due to
cyclic dependencies, so it gets the actual include path instead, which
is less bad than depending on the build system injecting the for all
modules.

d0ecf0b30d Adding system property tracing
Introducing a new systrace tag, TRACE_TAG_SYSPROP, for use with
system property.

For property set, the tracing is added in __system_property_set() instead of
__system_property_update() / __system_property_add() so we can record
control properties like ctl.*, sys.powerctl.*, etc.., which won't be
updated via the latter two functions.

8035caa311 Enable coverage for libc.
Bug: http://b/157081822

- Disable coverage for libtest_check_rtld_next_from_library to make
dlfcn.rtld_next_from_library to pass.
- The coverage runtime sets an environment variable to prevent
clobbering of the coverage data on disk.  Include that variable as well
when checking `printenv` output.  This is done at runtime by checking
for LLVM_PROFILE_FILE environment variable.
- dl.preinit_system_calls still fails after this change.

Test: bionic tests with libc coverage turned on.

a992a06701 x86: Switch get_pc_thunk to comdat
Switch the __x86.get_pc_thunk.{bx,cx} functions from .gnu.linkonce to
comdat section groups. lld doesn't implement .gnu.linkonce and will
instead discard the input sections. Currently, it might produce a
faulty binary that has no get_pc_thunk function in it, which would
crash.

Normally, these functions are generated by GCC and are present in many
object files compiled with PIC. Clang doesn't use them, and instead
initializes the PIC base register with a "call 1f; 1: pop %ebx" pair.
