Replace our ancient dtoa/strtod implementation with the gdtoa package, a more recent, generalized set of routines. Among the changes: - Declare strtof() and strtold() in stdlib.h. - Add glue to libc to support these routines for all kinds of ``long double''. - Update printf() to reflect the fact that dtoa works slightly differently now. As soon as I see that nothing has blown up, I will kill src/lib/libc/stdlib/strtod.c. Soon printf() will be able to use the new routines to output long doubles without loss of precision, but numerous bugs in the existing code must be addressed first.

Userland spinlocks bad. Sleep locks good. Use the latter for gdtoa. Requested by: deischen (far too long ago) 2003-06-21 08:20:14 +00:00			`#include <pthread.h>`
