bionic doesn't have an implementation for this function, but neither
does the kernel. cachectl has existed in the kernel as a stub that
returns ENOSYS for over a decade.

Clang static analyzer gives warning when address of
local variable 'attr' is saved in a global variable.
This change passes required values down to signal handler
instead of saving local variable address in a signal handler.

Add a clang-based tool to inspect header availability attributes and

These directories all have Android.bp files that are always used now,
delete the Android.mk files.

The typedefs for __u64 and __u32 aren't in scope in this file, so
switch fields declared with these to use the matching underlying type.

Add a new document that describes the previous version of malloc debug.
Add a small update to the current documentation to indicate it only
applies to N and later.

The unistd fsync/fdatasync were changed to use /data from /.
Unfortunately, this directory is unreadable unless you are root, so
change this path to /data/local/tmp.

The purpose of those tests is to ensure fsync succeeds for
directories. However, they try to call fsync for / (the root
filesystem) that is usually mounted read-only, which does not
make sense because the whole point of fsync is to flush
uncommitted changes to the filesystem.
In fact, some well-known read-only filesystems (e.g. squashfs)
does not support fsync, so these tests fail if we use such
filesystems as the root filesystem.
This patch changes the tests to call fsync against /data
instead. /data is a user data partition and should be always
mounted read-write.

There's no change to the generated stubs, because the script only cares
that this is a pointer type, not what it's a pointer to.

create_namespace resolves caller namespace only
when caller did not explicitly specify parent namespace.
This saves about 25 microseconds for the case when
parent_namepsace is not null (for example when creating
second classloader for the app).

This operation is the most expensive one and since it is
unlikely that the zip-entry name is invalid (given that it
is constructed by the platform) - it can removed.
The worst case scenario is dlopen() of non-existing libraries
taking more time. And this use-case is not on the critical path.

(cherry picked from commit a5c1c8e820)
This CL adds initialization of inode for the main executable
which enables linker to resolve the correct soinfo when
application calls dlopen with absolute path to the
main executable.

This change enables apps to share libraries opened
with RTLD_GLOBAL between different classloader namespaces.
The new parameter to create_namespace allows native_loader
to instruct the linker to share libraries belonging to
global group from a specified namespace instead of
using the caller_ns.
