Refactor strtod parsing of NaN payloads. The nan* functions handle their string argument by constructing a NAN(...) string on the stack as a VLA and passing it to strtod functions. This approach has problems discussed in bug 16961 and bug 16962: the stack usage is unbounded, and it gives incorrect results in certain cases where the argument is not a valid n-char-sequence. The natural fix for both issues is to refactor the NaN payload parsing out of strtod into a separate function that the nan* functions can call directly, so that no temporary string needs constructing on the stack at all. This patch does that refactoring in preparation for fixing those bugs (but without actually using the new functions from nan* - which will also require exporting them from libc at version GLIBC_PRIVATE). This patch is not intended to change any user-visible behavior, so no tests are added (fixes for the above bugs will of course add tests for them). This patch builds on my recent fixes for strtol and strtod issues in Turkish locales. Given those fixes, the parsing of NaN payloads is locale-independent; thus, the new functions do not need to take a locale_t argument.
