make __dtoa & strtod() thread-safe useing the same method as newer gdtoa

codebase. tested mostly by ckuethe and myself. __dtoa() use now requires a call to __freedtoa()

create special allocators for pginfo and pgfree structs instead of imalloc. this keeps them separated from application memory. for chunks, to prevent deterministic reuse, keep a small array and swizzle the to be freed chunk with a random previously freed chunk. this last bit only for chunks because keeping arbitrarily large regions of pages around may cause out of memory issues (and pages are, to some extent, returned in random order). all changes enabled by default. thanks to ben for pointing out these issues. ok tech@

mips64 handling too.. sigh
