bitops.h: sextract64() return type should be int64_t, not uint64_t

Browse Source 
The documentation for sextract64() claims that the return type is
an int64_t, but the code itself disagrees. Fix the return type to
conform to the documentation and to bring it into line with
sextract32(), which returns int32_t.
