Win32: reduce environment array reallocations

Move environment array reallocation from do_putenv to the respective
callers. Keep track of the environment size in a global variable. Use
ALLOC_GROW in mingw_putenv to reduce reallocations. Allocate a
sufficiently sized environment array in make_environment_block to prevent
reallocations.
