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.)

All functions which allocate objects containing AtomicRefCounts will soon need

* A segment with filesz == 0, memsz > 0 should be an anonymous only
mapping. We were failing to load such an ELF.
* Anonymous pages are always mapped RW, regardless of the segment
protections.

This does not actually implement an efficient splice or sendfile. Rather, it
adds a generic plumbing to the file internals so that this can be added. All
file implementations use the stub fileutil.NoSplice implementation, which
causes sendfile and splice to fall back to an internal copy.
A basic splice system call interface is added, along with a test.

This is in preparation for improved page cache reclaim, which requires
greater integration between the page cache and page allocator.

More helper structs have been added to the fsutil package to make it easier to

This change also adds extensive testing to the p9 package via mocks. The sanity
checks and type checks are moved from the gofer into the core package, where
they can be more easily validated.

Linux will ALWAYS add AT_BASE even for a static binary, expect it
will be set to 0 [1].

With musl libc when these entries are missing from the aux vector
it's forcing libc.secure (effectively AT_SECURE). This mode prevents
RPATH and LD_LIBRARY_PATH from working.

As the first entry is a mask of all the aux fields set:

Multiple whitespace characters are allowed. This fixes Ubuntu's
/usr/sbin/invoke-rc.d, which has trailing whitespace after the
interpreter which we were treating as an arg.

80bdf8a4068de3ac4a73b6b61a0cdcfe3e3571af accidentally moved vdso into an
inner scope, never assigning the vdso variable passed to the Kernel and
thus skipping VDSO mappings.
Fix this and remove the ability for loadVDSO to skip VDSO mappings,
since tests that do so are gone.
