Otherwise the lock upgrade performed by rtld's load_filtees() can result
in infinite recursion, wherein:
1. _rtld_bind() acquires the bind read lock,
2. the source DSO's filtees haven't been loaded yet, so the lock upgrade
in load_filtees() cause rtld to jump to _rtld_bind() and release the
bind lock,
3. _thr_rtld_lock_release() calls _thr_ast(), which calls thr_wake(),
which hasn't been resolved yet,
4. _rtld_bind() acquires the bind read lock in order to resolve
thr_wake(),

In order to atomically upgrade the rtld bind lock, load_filtees() may
trigger a longjmp back to _rtld_bind() so that the binding can be done
with the write lock held. However, the write lock is only needed when
filtee objects haven't already been loaded, so move the
lock_restart_for_upgrade() call to avoid unnecessary lock upgrades when
a filtee is defined.

Somehow this doesn't work iwth make packages due to some kind of a race.
The package is first created correctly but later in the process it is
overwritten by a badly created empty package.
Revert in the mean time so we can have working pkgbase on arm/arm64

The TCP implied connect is an artifact left after T/TCP. To my surprise
it still works, hence the existence of this test. Please read this email
first:
https://lists.freebsd.org/pipermail/freebsd-net/2010-August/026311.html
An interesting fact that this test takes 220 - 240 milliseconds to
execute on my Threadripper PRO. Flipping the '#if 0' to '#if 1' in the
test, thus bringing it back to normal connect(2), would speed the test up
a hundred times and I guess all this time is fork+exec of the test.

- Cover all code paths.
- When decoding, check all output files, not just the last one.
- A simple `ferror()` check is not enough as an error may later occur
while flushing whatever remains in the output buffer.

Most ULP modes in cxgbe's TOE are enabled on the fly when a protocol
is needed (e.g. ULP_MODE_ISCSI is enabled by cxgbei when offloading a
connection using iSCSI, and ULP_MODE_TLS is enabled when RX TLS keys
are programmed for a TOE connection). The one exception to this is
ULP_MODE_TCPDDP.
Currently the cxgbe driver enables ULP_MODE_TCPDDP when a TOE
connection is first created. However, since DDP connections cannot be
converted to other connection types, this requires some special
handling in the driver. For example, iSCSI daemons use the SO_NO_DDP
socket option to ensure TOE connections use ULP_MODE_NONE so they can
be converted to ULP_MODE_ISCSI. Similarly, using TLS receive offload
(ULP_MODE_TLS) requires disabling TCP DDP for new connections by
default.
This commit changes cxgbe to instead switch a connection from
ULP_MODE_NONE to ULP_MODE_TCPDDP when a connection first attempts to
use TCP DDP via aio_read(2). This permits connections to always start
as ULP_MODE_NONE and switch to a protocol-specific mode as needed.

Previously this was only limited on T6 cards to support switching from
ULP_MODE_NONE to ULP_MODE_TLS. To support switching to
ULP_MODE_TCPDDP, enable this for all adapters.

This is normally done by bsd.subdir.mk in its default distribute target,
but since etc overrides it we don't get that behaviour. Currently it's
not needed, but share/man's makedb (recursed into by etc's afterinstall)
will need it in the following commit. Technically this is only needed
for install, but do this for distribution too for completeness and
