After the commit a4705d387f, printf() for floating-point values
causes a memory leak. The legacy _ldtoa_r() assumed the char pointer
returned will be free'ed by Bfree(). However, gdtoa-based _ldtoa_r()
returns the pointer returned by gdtoa() which should be free'ed by
freedtoa(). Due to this issue, the caller of _ldtoa_r() fails to free
the allocated char buffer. This is the cause of the said memory leak.

This patch makes rv_alloc()/freedtoa() allocate/free the buffer in
a compatible way with legacy _ldtoa_r().

The extended _NL_foo names were originally designed after their GLibc
counterparts. However, the OUTDIGIT macros were accidentally defined as
OUTDIGITS, plural. Fix them.
