Make the cost of strto<signed> closer to the cost of strto<unsigned>
by removing an `if` from the inner loop. Previously a signed conversion
cost 10ns more than an unsigned one.
After:
BM_inttypes_strtoimax 81 ns 81 ns 8603362
BM_inttypes_strtoumax 78 ns 78 ns 8967174
BM_stdlib_strtol 81 ns 81 ns 8685537
BM_stdlib_strtoll 81 ns 81 ns 8685481
BM_stdlib_strtoul 78 ns 78 ns 8962569

There are no meaningful changes here, just a minimal conversion to two
C++ templates to make further changes easier.

Because I want something to copy & paste into the NDK support library test
that's slightly better than taking the address of the function...

I've half a mind to make this a warning instead, since this sort of
call isn't UB. That said:
- if the user really wants this (I can't imagine why they would), they
can just put NULL in a non-const variable,
- we're slowly moving to -Werror ~everywhere anyway, and
- it's presumably easier to change this from an error to a warning than
the other way around

Move all tests into stdlib_test.cpp since that's where the definition lives
in bionic.
Add a sweep test and a various size test.
Test: Run new unit tests on glibc and angler.

The parsefloat routines -- which let us pass NaNs and infinities on to
strto(f|d|ld) -- come from NetBSD.
Also fix LP64's strtold to return a NaN, and fix all the architectures
to return quiet NaNs.
Also fix wcstof/wcstod/wcstold to use parsefloat so they support hex
floats.
Lots of new tests.

Also clean up the implementation of all the pty functions, add tests,
and fix the stub implementations of ttyname(3) and ttyname_r(3).

Code developed for glibc or older versions of bionic might expect more
randomness than the BSD implementation provides.

I've also switched some tests to be positive rather than negative,
because !defined is slightly harder to reason about and there are
only two cases: bionic and glibc.

The normal ASSERT_EQ macros don't work quite right for float/double values,
and result in false failures. Use the correct macros instead.

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.

Let the kernel keep pthread_internal_t::tid updated, including
across forks and for the main thread. This then lets us fix
pthread_join to only return after the thread has really exited.
Also fix the thread attributes of the main thread so we don't
unmap the main thread's stack (which is really owned by the
dynamic linker and contains things like environment variables),
which fixes crashes when joining with an exited main thread
and also fixes problems reported publicly with accessing environment
variables after the main thread exits (for which I've added a new
unit test).
In passing I also fixed a bug where if the clone(2) inside
pthread_create(3) fails, we'd unmap the child's stack and TLS (which
contains the mutex) and then try to unlock the mutex. Boom! It wasn't
until after I'd uploaded the fix for this that I came across a new
public bug reporting this exact failure.

This is actually a slightly newer upstream version than the one I
originally pulled. Hopefully now it's in upstream-freebsd it will
be easier to track upstream, though I still need to sit down and
write the necessary scripts at some point.
