malloc/nano-malloc: correctly check for out-of-bounds allocation reqs

The overflow check in mEMALIGn erroneously checks for INT_MAX,
albeit the input parameter is size_t.  Fix this to check for
__SIZE_MAX__ instead.  Also, it misses to check the req against
adding the alignment before calling mALLOc.

While at it, add out-of-bounds checks to pvALLOc, nano_memalign,
nano_valloc, and Cygwin's (unused) dlpvalloc.
