mremap handling in case of error and creating a duplicate mapping.
...
- mremap can fail, in this case the old mapping is retained.
- mremap, when oldsize is 0, a new mapping is created without freeing
the old one.
See mremap(2) for details.

munmap can fail.
...
According to munmap(2), the call can fail, e.g if the adress given is
not at a page boundary.

Consider page size in report_mmap / report_unmap.
...
mmaps are full of quirks ;-)
- mmap(2) will always allocate whole memory pages, even if the
caller only reuqests a partial page.
This is considered by calculating the "real" size of the mmap.
- munmap(2) also operates on pages, unmapping every page it "touches.",
so the size parameter is adjusted if needed.
