Ayush Ranjan a9441aea27 [op] Replace syscall package usage with golang.org/x/sys/unix in pkg/.
The syscall package has been deprecated in favor of golang.org/x/sys.

Note that syscall is still used in the following places:
- pkg/sentry/socket/hostinet/stack.go: some netlink related functionalities
  are not yet available in golang.org/x/sys.
- syscall.Stat_t is still used in some places because os.FileInfo.Sys() still
  returns it and not unix.Stat_t.

Updates #214

Ayush Ranjan 1375a87a20 [netstack] Refactor common utils out of netstack to socket package.
Moved AddressAndFamily() and ConvertAddress() to socket package from netstack.
This helps because these utilities are used by sibling netstack packages.

Such sibling dependencies can later cause circular dependencies. Common utils
shared between siblings should be moved up to the parent.

Dean Deng d01a8ca347 Add FileDescription interface for socket files.
Refactor the existing socket interface to share methods between VFS1 and VFS2.
The method signatures do not contain anything filesystem-related, so they don't
need to be re-defined for VFS2.

Updates #1476, #1478, #1484, #1485.

Adin Scannell 0e2f1b7abd Update package locations.
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.

Rahat Mahmood 7bfad8ebb6 Return a well-defined socket address type from socket funtions.
Previously we were representing socket addresses as an interface{},
which allowed any type which could be binary.Marshal()ed to be used as
a socket address. This is fine when the address is passed to userspace
via the linux ABI, but is problematic when used from within the sentry
such as by networking procfs files.

Adin Scannell 753da9604e Remove map from fd_map, change to fd_table.
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.)
