This patch adds 80% of UINT32_MAX limit on sequence number.
When sequence number reaches limit kernel sends SADB_EXPIRE message to
IKE daemon which is responsible to perform rekeying.

Implement support for including IPsec ESN (Extended Sequence Number) to
both encrypt and authenticate mode (eg. AES-CBC and SHA256) and combined
mode (eg. AES-GCM). Both ESP and AH protocols are updated. Additionally
pass relevant information about ESN to crypto layer.
For the ETA mode the ESN is stored in separate crp_esn buffer because
the high-order 32 bits of the sequence number are appended after the
Next Header (RFC 4303).
For the AEAD modes the high-order 32 bits of the sequence number
[e.g. RFC 4106, Chapter 5 AAD Construction] are included as part of
crp_aad (SPI + ESN (32 high order bits) + Seq nr (32 low order bits)).

As RFC 4304 describes there is anti-replay algorithm responsibility
to provide appropriate value of Extended Sequence Number.
This patch introduces anti-replay algorithm with ESN support based on
RFC 4304, however to avoid performance regressions window implementation
was based on RFC 6479, which was already implemented in FreeBSD.
To keep things clean and improve code readability, implementation of window
is kept in seperate functions.

We convert a string like "W32:vendor/device" into "I:vendor;I:device",
where the output is longer than the input, but only allocate space equal

Instead use open_memstream so we get a safe dynamically-grown buffer.

Ryzens do not implement the accessed MSR at all, it is documented as

idle state, so activate workaround only when on bare hardware.
While there, style the code:

It may be worthwhile doing it in case gcc-as demands we liberally sprinkle

The new C test takes 25 seconds on QEMU-RISC-V, wheras the shell version
takes 332 seconds.
Even with the latest optimizations to atf-sh this test still takes a few
seconds to startup in QEMU. Re-writing it in C reduces the runtime for a
single test from about 2-3 seconds to less than .5 seconds. Since there
are ~80 tests, this adds up to about 3-4 minutes.
This may not seem like a big speedup, but before the recent optimizations
to avoid atf_get_srcdir, each test took almost 100 seconds on QEMU RISC-V
instead of 3. This also significantly reduces the time it takes to list
the available test cases, which speeds up running the tests via kyua:
