c713eaa603 Bring in the vendor's fix for a bug in strtod() whereby
strtod("0xyz", &endp) resulted in endp pointing to "0xyz"
instead of "xyz".

9cb4166881 On platforms where long is 64 bits, make sure gdtoa doesn't use a
long when it really wants an int.

fb048cca0c Fix previous commit: We should only mask the top bit in the STRTOG_NaNBits
case, not the STRTOG_Normal case.

10a381e55a 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.

2ca7a12a81 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().

d086ded323 Userland spinlocks bad. Sleep locks good.
Use the latter for gdtoa.

6836976246 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.
