Fix lots of bugs due to newer kernel 5.8 in Ubuntu 20.04, and OpenZFS v0.8:

1. clone_extents_to() didn't handle partial clones, and now it does.

2. OpenZFS has a bug in SEEK_DATA which caused empty clones, we use a hacky
workaround to fix it.

3. mapped_file_handle now fails loudly if it fails to allocate the map due
to VMA exhaustion. This closes off a ton of unpleasant surprise in heavily
loaded applications.

4. If your Linux kernel was old enough, or you are on ZFS, renaming a
mapped_file_handle caused internal state corruption which led to lots of
bad things, including `bad_file_descriptor` errors.

5. On Windows, renaming a mapped_file_handle now tears down and restores
the maps, as you cannot rename a file with open maps.

mapped_file_handle::read() and write() was not detecting when VA space had been exhausted, and was incorrectly segfaulting the process rather than returning errc::not_enough_memory.
