c22a7de798 extend the PTRDIFF_MAX size check to mremap
This removes another way to obtain objects larger than PTRDIFF_MAX. The
only known remaining hole is now jemalloc's merging of virtual memory
spans.

Technically this could be wrapped in an __LP64__ ifndef since it can't
occur on 64-bit due to the 1:1 split. It doesn't really matter either
way.

4200e260d2 fix the mremap signature
The mremap definition was incorrect (unsigned long instead of int) and
it was missing the optional new_address parameter.

eda26bc1ff Add/Remove mmap tests.
Remove the incorrect tests that use a negative offset for mmap without
a fd.

Add a small set of tests for mmap.

0e44bc3bae Remove <asm/page.h>.
If we have PAGE_SIZE/PAGESIZE, POSIX says they should be in <limits.h>.

431166d995 Fix 32-bit mmap/mmap64 handling of negative offsets.
We don't actually need to worry about sign extension if we reject
negative values ourselves. Previously it was possible to come up
with negative but aligned values that we would pass to the kernel;
in the case of mmap (as opposed to mmap64) we'd incorrectly turn
those into large positive offsets.
