When a dataset is in the process of being received it gets marked as
inconsistent and should not be used. We should check for this when
opening a dataset handle in libzfs and return with an appropriate error
set, rather than hitting an abort because of the incomplete data.
zfs_open() passes errno to zfs_standard_error() after observing
make_dataset_handle() fail, which ends up aborting if errno is 0.
Set errno before returning where we know it has not been set already.

`configure` now accepts `--enable-asan` and `--enable-ubsan` switches
which results in passing `-fsanitize=address`
and `-fsanitize=undefined`, respectively, to the compiler. Those
flags are enabled in GitHub workflows for ZTS and zloop. Errors
reported by both instrumentations are corrected, except for:
- Memory leak reporting is (temporarily) suppressed. The cost of
fixing them is relatively high compared to the gains.
- Checksum computing functions in `module/zcommon/zfs_fletcher*`
have UBSan errors suppressed. It is completely impractical
to enforce 64-byte payload alignment there due to performance
impact.
- There's no ASan heap poisoning in `module/zstd/lib/zstd.c`. A custom
memory allocator is used there rendering that measure
unfeasible.
- Memory leaks detection has to be suppressed for `cmd/zvol_id`.
`zvol_id` is run by udev with the help of `ptrace(2)`. Tracing is
incompatible with memory leaks detection.

The FreeBSD implementations of various libspl functions for getting
mounted device information were found to leak several strings which
were being allocated in statfs2mnttab but never freed.
The Solaris getmntany(3C) and related interfaces are expected to return
strings residing in static buffers that need to be copied rather than
freed by the caller.
Use static thread-local storage to stash the mnttab structure strings
from FreeBSD's statfs info rather than strings allocated on the heap by
strdup(3).
While here, remove some stray commented out lines.
