On platforms where long is 64 bits, make sure gdtoa doesn't use a

long when it really wants an int.

Fix strto{f,d,ld}() so they don't return signaling NaNs. C99
...
says they are never supposed to, and the fact that they did could
cause apps that run with unmasked FP exceptions to SIGFPE after a
scanf() or strtod(). The vendor stated that he will not be fixing
this, citing portability concerns.

Some changes the vendor didn't want:
...
- Accept the '0x' prefix so strtod("nan(0x...)", NULL) returns the same
thing as gcc's builtin nan("0x...") for such strings.
- Don't return uninitialized memory.
- Finish processing the string up to the closing ')' (provided it's
lexically valid) for compatibility with C99 and *scanf().

Userland spinlocks bad. Sleep locks good.

Use the latter for gdtoa.

Add some missing prototypes to eliminate some warnings. These already

appear without leading underscores in gdtoa.h, but this approach avoids
removing that file from the vendor branch and unduly rearranging things.
