Issue #1833

Without this change, the assembly code of this test compiled without
optimizations:
mov -0x150(%rbp),%rax
movl $0x77777777,(%rax)
lea -0x128(%rbp),%rax
with optimizations:
movl $0x77777777,0x0
This code doesn't work properly, because the test changes rax in the segv
handler.

In VFS2, imported file descriptors are stored in a kernfs-based filesystem.
Upon calling ImportFD, the host fd can be accessed in two ways:
1. a FileDescription that can be added to the FDTable, and
2. a Dentry in the host.filesystem mount, which we will want to access through
magic symlinks in /proc/[pid]/fd/.
An implementation of the kernfs.Inode interface stores a unique host fd. This
inode can be inserted into file descriptions as well as dentries.
This change also plumbs in three FileDescriptionImpls corresponding to fds for
sockets, TTYs, and other files (only the latter is implemented here).
These implementations will mostly make corresponding syscalls to the host.
Where possible, the logic is ported over from pkg/sentry/fs/host.

When list elements are removed from a list but not discarded, it becomes
important to invalidate the references they hold to their former
neighbors to prevent memory leaks.

Adds an oom_score_adj and oom_score proc file stub. oom_score_adj accepts
writes of values -1000 to 1000 and persists the value with the task. New tasks
inherit the parent's oom_score_adj.
oom_score is a read-only stub that always returns the value '0'.

By putting slices into the pool, the slice header escapes. This can be avoided
by not putting the slice header into the pool.
This removes an allocation from the TCP segment send path.

$RANDOM can cause collisions but shuf uses /dev/urandom so it ought to cause

gofer.dentryReadWriter.WriteFromBlocks was not updating
gofer.dentry.size after a write operation that skips the

The support of PTRACE_SYSEMU on arm64 was added in the 5.3 kernel,
so we can be sure that the current version is higher that 5.3.
And this change moves vsyscall seccomp rules to the arch specific file,
because vsyscall isn't supported on arm64.

Ensures that all access to TransportEndpointInfo.ID is either:
* In a function ending in a Locked suffix.
* While holding the appropriate mutex.
This primary affects the checkV4Mapped method on affected endpoints, which has
been renamed to checkV4MappedLocked. Also document the method and change its
argument to be a value instead of a pointer which had caused some awkwardness.
This race was possible in the udp and icmp endpoints between Connect and uses
of TransportEndpointInfo.ID including in both itself and Bind.
The tcp endpoint did not suffer from this bug, but benefited from better
documentation.

A deadlock may occur if a write lock on a RWMutex is blocked between
nested read lock attempts as the inner read lock attempt will be
blocked in this scenario.
Example (T1 and T2 are differnt goroutines):
T1: obtain read-lock
T2: attempt write-lock (blocks)
T1: attempt inner/nested read-lock (blocks)
Here we can see that T1 and T2 are deadlocked.
Tests: Existing tests pass.
