1. Personality parameter should be unsigned int (not long)
2. Do not reset bits outside of PER_MASK when setting
personality value.
3. Set personality for static executables.

We don't want to use <asm/ptrace.h> because (a) it'll drag in a bunch of
namespace pollution and (b) the registers should be "long double" for
userspace, not the kernel's uint128s. So just use a slightly different
name for our struct (which matches the traditional names for these structs
anyway).

(cherry picked from commit 0577733c2e)
The pthread_mutex_lock and pthread_mutex_unlock were allowed to
fail silently on L 32 bit devices when passed a NULL. We changed
this to a crash on 32 bit devices, but there are still games that make
these calls and are not likely to be updated. Therefore, once again
allow NULL to be passed in on 32 bit devices.

Adds a new _internal_ function. Provide a global serial number to
support more efficient private caching algorithms. This allows
to skip re-running the __system_property_find() call on misses until
there is a global change in the properties. This call is a read
barrier, the property data to be read following this call will be
read sequentially and up to date.

Previous implementation of rwlock contains four atomic variables, which
is hard to maintain and change. So I make following changes in this CL:
1. Add pending flags in rwlock.state, so we don't need to synchronize
between different atomic variables. Using compare_and_swap operations
on rwlock.state is enough for all state change.
2. Add pending_lock to protect readers/writers waiting and wake up
operations. As waiting/wakeup is not performance critical, using a
lock is easier to maintain.
3. Add writer preference option.
4. Add unit tests for rwlock.

This flag allows to force loading of the library
in the case when for some reason multiple ELF files
share the same filename (because the already-loaded
library has been removed and overwritten, for example).

These macros are also not used in glibc. And we should use
PTHREAD_RECURSIVE_MUTEX_INITIALIZER_NP
and PTHREAD_ERRORCHECK_MUTEX_INITIALIZER_NP instead.

This is currently set in init.rc, but I plan on making init
set PATH to _PATH_DEFPATH and removing the line from init.rc...

/dev/mem (and /dev/kmem) are not enabled in the kernels, and selinux
prevents access and makes it a rule compilation error to enable
access. No code uses the _PATH_MEM macro. Remove definition to
suppress future usage.
