Delete jsstddef.h, since its only remaining purpose is to make certain
Win16-specific definitions; we don't support Win16 any more. In
particular, we can just subtract pointers now, so the PTRDIFF macro is
unnecessary noise.
Most places get stddef.h via jstypes.h or some other header, so we can
just delete #inclusions of jstddef.h. The exception is jskwgen.h, so
there we explicitly include <stddef.h> instead.
* Various code inside and outside of JS uses JS_BYTES_PER_WORD, so I added it to js-config.h
* Existing code uses JS_BYTES_PER_DOUBLE, JS_BITS_PER_WORD_LOG2, and JS_ALIGN_OF_POINTER so I've added autoconf tests for those

Perform the appropriate configure-time tests, and hard-code the
answers for targets that don't support autoconf-style tests. Check
for the io.h header, and the setbuf and isatty library functions.
In js/src/xpconnect/shell/xpcshell.cpp, use configure-#defined
preprocessor symbols to decide what to #include and use. The
top-level configure script defines the preprocessor symbols used here.
In js/src/prmjtime.cpp, use them to select the appropriate method for
retrieving fine-grained time information for Windows and WinCE. The
js/src/configure script defines the preprocessor symbols used here.
(This should cover the issues addressed by patch.v2 in bug 461841,
except for the stdint issue.)
Every piece of the body of js/src/prmjtime.cpp's PRMJ_Now function was
in a preprocessor conditional --- it was three entirely independent
implementations shuffled together. Unshuffling them prepares the way
for adding a new WinCE definition.
