Go 1.14 has a workaround for a Linux 5.2-5.4 bug which requires mlock'ing the g
stack to prevent register corruption. We need to allow this syscall until it is
removed from Go.

If the support is Ignored, then the call is still executed. We
simply rely on it to fall through to the int3. Therefore, we
must also bail on the vendor check.

As per RFC 2464 section 7, an IPv6 packet with a multicast destination
address is transmitted to the mapped Ethernet multicast address.

This avoids conflicting definitions of GetSocketPairs() in outer namespace when
multiple such cc files are complied for one binary.

When sending a RST on shutdown we need to double check the
state after acquiring the work mutex as the endpoint could
have transitioned out of a connected state from the time
we checked it and we acquired the workMutex.
I added two tests but sadly neither reproduce the panic. I am
going to leave the tests in as they are good to have anyway.

Splice must not allow negative offsets. Writes also must not allow offset +
size to overflow int64. Reads are similarly broken, but not just in splice
(b/148095030).

Currently, Send() will copy data into a new byte slice without regard to the
original size. Size checks should be performed before the allocation takes
place.
Note that for the sake of performance, we avoid putting the buffer
allocation into the critical section. As a result, the size checks need to be
performed again within Enqueue() in case the limit has changed.

WritableSource is a convenience interface used for files that can
be written to, e.g. /proc/net/ipv4/tpc_sack. It reads max of 4KB
and only from offset 0 which should cover most cases. It can be
extended as neeed.

FD table now holds both VFS1 and VFS2 types and uses the correct
one based on what's set.
Parts of this CL are just initial changes (e.g. sys_read.go,
runsc/main.go) to serve as a template for the remaining changes.

Special files can have additional requirements for granularity.
For example, read from eventfd returns EINVAL if a size is less 8 bytes.

This isn't in the libc wrapper, but it is in the syscall itself.

And Type* over Type *. This is basically a whitespace only change.
gVisor code already prefers left-alignment of pointers and references, but
clang-format formats for consistency with the majority of a file, and some
files leaned the wrong way. This is a one-time pass to make us completely
conforming.
Autogenerated with:
$ find . \( -name "*.cc" -or -name "*.c" -or -name "*.h" \) \
| xargs clang-format -i -style="{BasedOnStyle: Google, \
DerivePointerAlignment: false, PointerAlignment: Left}"

In general, we've learned that logging must be avoided at all
costs in the hot path. It's unlikely that the optimizations
here were significant in any case, since buffer would certainly
escape.
This also adds a test to ensure that the caller identification
works as expected, and so that logging can be benchmarked.

Because the abi will depend on the core types for marshalling (usermem,
context, safemem, safecopy), these need to be flattened from the sentry
directory. These packages contain no sentry-specific details.

gonet.Conn can be created with both gonet.NewConn and gonet.Dial.
gonet.PacketConn was created only by gonet.DialUDP. This prevented
us from being able to use PacketConn in udp.NewForwarder() context.
This simple constructor - NewPacketConn, allows user to create
correct structure from that context.
