look(1): use a stricter pledge(2) in lieu of unveil(2)

We're only reading one file here, so unveil(2) is overkill.  We can
achieve the same effect with just pledge(2):

- Start with an initial pledge(2) of "stdio rpath" at the top of main().
  We know we need to read a file at this point but don't yet know which
  one.

- Drop the pledge(2) down to "stdio" after we open(2) and fstat(2) the
  chosen file.

- Dropping "rpath" obviates unveil(2).

2 years agobring back IPv4, TCP4/6 and UDP4/6 checksum offloading.

bring back IPv4, TCP4/6 and UDP4/6 checksum offloading.

this was first introduced in r1.176 by jan@. this diff includes two
fixes to that implementation.

the most important one is to parse the ip and tcp headers before a
possible call to m_defrag. if an l4 offload is requested, it's only
requested by the stack when the payload is correctly aligned and
with each header contiguous in memory. this means you can use
m_getptr and cast the packet data to the relevant headers to read
them directly because that's what the stack does when it's working
on them. this makes it cheap to work on them too.

however, if you m_defrag, it ignores the alignment and ends up
making it unsafe to dereference the ip and tcp/udp payloads on
strict alignment architectures. if we want to look at the headers
after m_defrag, we'd likely have to copy them onto the stack first.

the other fix is to reset the offload bits between packets in the
loop in ixl_start.

another difference is that this code skips parsing the packet if
no checksum offload is requested.

Implement the poll(2) system call on top of the kqueue subsystem.
This obsoletes the old, non-MP-safe poll backend.

On entering poll(2), the new code translates each pollfd array entry
into a set of knotes. When these knotes receive events through kqueue,
the events are translated back to pollfd format.

Entries in the pollfd array can refer to the same file descriptor with
overlapping event masks. To allow such overlap with knotes, use an extra
kn_pollid key that separates knotes of different pollfd entries.

Add a workaround due to OpenSSL's limitation of SSL_CTX_set_cipher_list

SSL_CTX_set_cipher_list() in OpenSSL 1.1 does not accept TLSv1.3 ciphers.
This wasn't a problem until now since the AEAD- ciphers were counted as
distinct from TLS_ ciphers by the regress test, so they were never used
in the {run,check}-cipher-${cipher}-client-${clib}-server-${slib} tests

With the renaming, the TLSv1.3 ciphers are now considered as common
ciphers, so they're tested. With openssl11 this results in

0:error:1410D0B9:SSL routines:SSL_CTX_set_cipher_list:no cipher match:ssl/ssl_lib.c:2573:

The design of these tests doesn't allow easily adding a call to
SSL_CTX_set_ciphersuites (since they also need to work with openssl 1.0.2)
so skip the TLS_* ciphers for the time being.
