* libc/include/stdlib.h (unsetenv, _unsetenv_r): Redefine with integer
return types.
* libc/stdlib/getenv_r.c (_findenv_r): Do no special processing with
names that contain equal chars.
* libc/stdlib/setenv.c: Redefine _unsetenv_r as returning int.
* libc/stdlib/setenv_r.c (_setenv_r): Return -1 and set errno to
EINVAL if name contains an equal sign. Do not remove any equal signs
from the value.
(_unsetenv_r): Modified to return int. Return -1 and set EINVAL
if name contains equal sign. Return -1 if no variable(s) were found
and return 0 otherwise.

rv, rv0 from double to type U. Use accessor macros dval, dword0
and dword1 for all accesses except for the ULtod call, where rv.i

of access macros. Tweak comment.
Remove #ifdef'd YES_ALIAS code.

access. Ditto for _DOUBLE_IS_32BITS variants.

_svfprintf_r which is optimized to work with sprintf family of
functions and not use I/O.

family of functions (i.e. no I/O) and no float-point support.

__ssvfscanf_r which is optimized to work with sscanf family of
functions and does not require I/O functions.
