This is needed for syzkaller to proper classify issues.
Right now, all watchdog issues are duped to one with the
subject "panic: Sentry detected stuck task(s). See stack
trace and message above for more details".

There is no cpuid instruction on arm64, so we need to defined it
just to avoid a compile time error.

A follow-up change will convert the networking code to use this standard
pipe implementation.

/dev/net/tun does not currently work with hostinet. This has caused some
program starts failing because it thinks the feature exists.

We changed syscalls to allow dup3 for ARM64.

Call stack.Close on stacks when we are done with them in tcp_test. This avoids
leaking resources and reduces the test's flakiness when race/gotsan is enabled.
It also provides test coverage for the race also fixed in this change, which
can be reliably triggered with the stack.Close change (and without the other
changes) when race/gotsan is enabled.
The race was possible when calling Abort (via stack.Close) on an endpoint
processing a SYN segment as part of a passive connect.

Analogous to Linux's kern_mount().

MayDelete must lock the directory also, otherwise concurrent renames may
race. Note that this also changes the methods to be aligned with the actual
Remove and RemoveDirectory methods to minimize confusion when reading the
code. (It was hard to see that resolution was correct.)

pipe and pipe2 aren't ported, pending a slight rework of pipe FDs for VFS2.
mount and umount2 aren't ported out of temporary laziness. access and faccessat
need additional FSImpl methods to implement properly, but are stubbed to
prevent googletest from CHECK-failing. Other syscalls require additional
plumbing.

Each mount is holds a reference on a root Dirent, but the mount itself may
live beyond it's own reference. This means that a call to Root() can come
after the associated reference has been dropped.
Instead of introducing a separate layer of references for mount objects,
we simply change the Root() method to use TryIncRef() and allow it to return
nil if the mount is already gone. This requires updating a small number of
callers and minimizes the change (since VFSv2 will replace this code shortly).

TestCurrentConnectedIncrement fails consistently under gotsan due to the sleep
to check metrics is exactly the same as the TIME-WAIT duration. Under gotsan
things can be slow enough that the increment test is done before the protocol
goroutine is run after the TIME-WAIT timer expires and does its cleanup.
Increasing the sleep from 1s to 1.2s makes the test pass consistently.

Protocol dispatchers were previously leaked. Bypassing TIME_WAIT is required to
test this change.
Also fix a race when a socket in SYN-RCVD is closed. This is also required to
test this change.
