This is an implementation in the style of the rest: char == byte.
We might want to come back and implement UTF-8, but this is enough for ltrace.

If we're not going to wait for the timer threads to exit, we need
another way to ensure that we don't free the data they're using
prematurely. The easiest way to ensure that is to let them free the
data themselves.

- parsing of fractional part was wrong (always parsed as 0)
- return value was also wrong in the presence of fractional parts
- general style clean up

There are only three users of bionic definition of ALIGN and keeping it
in sys/param.h polutes the namespace.
I inline the definition in the the three places that's used.

If the callback function for a timer did a timer_delete, the function
would never return. The problem was that the timer_delete function would try
to wait until the timer thread has finished. Waiting for yourself to finish
doesn't work very well.

__system_property_serial just returned serial value without
checking if it is dirty, so check and wait until serial
value is not dirty before return

We'll need a better implementation of strtold for LP64, but all our
long double functions are currently broken for LP64 anyway so this
isn't a regression.

It's safe to fix our constant definitions because we know we never
had symbols before, so can't be passing the bad old constants to the new
functions, or the correct new constants to the old inlines.

The new implementation is a better approximation to the processor time used
by the process because it's actually based on resource usage rather than just
elapsed wall clock time.

Functions protected with !defined(__LP64__) will be get build as C++
symbols for X64 build. This is not the desired work. So protect the
implementation with !defined(__LP64__) as well.

GCC is removing these checks anyway because it knows the arguments
must be non-null, so leaving this code around is just confusing.
We know from experience that people were shipping code with locking
bugs because they weren't checking for error returns. Failing hard
like glibc does seems the better choice. (And it's what the checked
in code was already doing; this patch doesn't change that. It just
makes it more obvious that that's what's going on.)

This replaces the non-standard pthread_mutex_lock_timeout_np, which we have

We only support CLOCK_REALTIME and CLOCK_MONOTONIC for now,
so we us a single bit from pthread_cond_t->value to denote
the clock type. Note that this reduces the width of the counter
to 30 bits, but this should be large enough for all practical
purposes.

Note that a dynamically-linked binary will still probably see two attempts ---
one by the dynamic linker (which will set its copy of the flag so it won't try
again) and then one by the executable itself (which gets a new uninitialized
copy of the flag).

When libc.debug.malloc is enabled, stack backtraces fail with:
bionic/libc/bionic/libc_logging.cpp:378: assertion "conversion
specifier unsupported" failed
The cause was a change to the format specifier from "%08x" to
"%0*x" to pass the field width as an additional parameter.
Unfortunately this modifier isn't supported by out_vformat() in
libc_logging.cpp.
Changed to use "%016x" if __LP64__ is defined; "%08x" otherwise.

A warning about signed vs unsigned comparison was converted
into an error here :
...
struct stat st;
if (st.st_size > sizeof(prop_area) {
...
st_size is either an off64_t, which is a signed type. It's
worth investigating why this didn't trigger a warning on 32 bit,
where it's signed as well.

This change constitutes the minimum amount of
work required to move the code over to C++, address
compiler warnings, and to make it const correct and
idiomatic (within the constraints of being called
from C code).

This gives us:
* <dirent.h>
struct dirent64
readdir64, readdir64_r, alphasort64, scandir64
* <fcntl.h>
creat64, openat64, open64.
* <sys/stat.h>
struct stat64
fstat64, fstatat64, lstat64, stat64.
* <sys/statvfs.h>
struct statvfs64
statvfs64, fstatvfs64.
* <sys/vfs.h>
struct statfs64
statfs64, fstatfs64.
This also removes some of the incorrect #define hacks we've had in the
past (for stat64, for example, which we promised to clean up way back
in bug 8472078).

bionic/libc/arch-arm64/syscalls/read.S ends with:
b.hi __set_errno
ret
END(read)
If __set_errno returns int, it will set w0 to 0xFFFFFFFF, which means
x0 is 0x00000000FFFFFFFF. When interpreted as a ssize_t that is
INT_MAX, not -1.
Change __set_errno to return long, which will cause x0 to be set instead
of w0.
