There were two bugs here:
- For 64 bit values, this did not properly round up.
- The macro rounded to the power of 2 less than value, not to the power
of 2 greater than value.

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

It's okay for a program to choose to drag in stdio, but it's unfortunate
if even the minimal "int main() { return 42; }" drags in stdio...
This brings the minimal static binary on ARM down from 78KiB to 46KiB.
Given that we don't have a separate -lpthread it's not obvious to me that
we can shave this down any further. I'm not sure whether this is a worthwhile
change for that reason. (And the fact that dynamic binaries, the usual case,
are unaffected either way.)

This lock has been here since the original commits, but as far as I can tell
it never served any purpose. We've never had a free list of cached stacks or
anything like that.

gdb won't even try to use this on Android because it knows we don't
support old enough kernels to need it.

The inclusion of the static libc_common library in the malloc_debug_XXX.so
shared libraries causes constructors to be called twice. This doesn't seem
to have caused any issues when setting the libc.debug.malloc property.
However, jemalloc crashes because there are two jemalloc implementations,
one in the static libc_common library and one in the shared library. Each
implementation has created overlapping thread keys that are not the same.
The crash comes because one of the jemalloc keys is actually used by the
locale setting code. Thus if someone sets the locale, the jemalloc code
crashes trying to access the same key.

Since we only support the C locale, we can just forward all of these to
their non-locale equivalents for correct behavior.

Accidentally verified against a dirty tree. Needs the companion change to libc++ to land upstream before I can submit this.
This reverts commit e087eac404b0e30de427392065e2750acf92bd4a.

Also fix a few formatting issues in copyright headers that were confusing
the script (though obviously it would be better if the script were smarter).
