This renames FDMap to FDTable and drops the kernel.FD type, which had an entire
package to itself and didn't serve much use (it was freely cast between types,
and served as more of an annoyance than providing any protection.)
Based on BenchmarkFDLookupAndDecRef-12, we can expect 5-10 ns per lookup
operation, and 10-15 ns per concurrent lookup operation of savings.
This also fixes two tangential usage issues with the FDMap. Namely, non-atomic
use of NewFDFrom and associated calls to Remove (that are both racy and fail to
drop the reference on the underlying file.)

We don't have the plumbing for btime yet, so that field is left off. The
returned mask indicates that btime is absent.

For a symbol link to some directory, eg.
`/tmp/symlink -> /tmp/dir`
`fstatat("/tmp/symlink")` should return symbol link data, but
`fstatat("/tmp/symlink/")` (symlink with trailing slash) should return
directory data it points following linux behaviour.
Currently fstatat() a symlink with trailing slash will get "not a
directory" error which is wrong.

CopyObjectOut grows its destination byte slice incrementally, causing
many small slice allocations on the heap. This leads to increased GC and
noticeably slower stat calls.

We accidentally set the wrong maximum. I've also added PATH_MAX and
NAME_MAX to the linux abi package.
