Make sure to reclaim epoch structures when they are freed to support
dynamic allocation and freeing of epoch structures.
While at it, move the 64 supported epoch control structures to the
static memory domain. This overall simplifies the management and
debugging of system epoch's.

When using v4-mapped IPv6 sockets with IPV6_PKTINFO we do not
respect the given v4-mapped src address on the IPv4 socket.
Implement the needed functionality. This allows single-socket
UDP applications (such as OpenVPN) to work better on FreeBSD.

Add IEEE80211_IOC_IC_NAME to query the ic_name field and in ifconfig
to print the parent interface again. This functionality was lost
around r287197. It helps in case of multiple wlan interfaces and
multiple underlying hardware devices to keep track which wlan
interface belongs to which physical device.

Netmap only uses free list 0 to keep it consistent with its
one-to-one mapping between each netmap ring and a device RX
(or TX) queue.
However, the current iflib_netmap_rxsync() routine was
mistakenly updating the ifl_cidx field of both free lists.

We need to provide a struct passwd that is compatible with the target
system and this is not the case when cross-building from macOS/Linux.
It should also be a problem when bootstrapping for an i386 target from a
FreeBSD amd64 host since time_t does not match across those systems.
However, pwd_mkdb always truncates integer values to 32-bit so this
difference does not result in different databases.

This does not appear to matter on FreeBSD or Linux, but when building an
amd64 kernel on macOS I was seeing infinite loops in ctfmerge.
It turns out the loop in wip_save_work() was looping forever due to
pthread_cond_wait() always returning -EINVAL.

It allows to report to initiator LU identifying information, preset via
"ident_info" and "text_ident_info" options.
Unfortunately it is impossible to implement SET IDENTIFYING INFORMATION,
since we have no persistent storage it requires, so the information is
read-only for initiator and has to be set out-of-band.

On ELFv2, the overflow parameters in the stack frame are at a different offset
from sp than ELFv1. Adjust code to use the correct offset in all cases.
This had resulted in argv[8] and up being copied to the incorrect address
in the new context's initial stack frame.
This is not necessarily the only bug in this function, I need to do a full
review still and ensure the rest of the math is sane for ELFv2 stack frames.

The output dir is set to ${REPODIR}/${PKG_ABI}/${PKG_VERSION} now.
Add the possibility to specify the last componant and set it by default
to ${PKG_VERSION} as before.
This is useful for tests and also for building packages with the same
PKG_VERSION provided to check differences.
libarchive uses the SOURCE_DATE_EPOCH env variable to set the date of file
in an archive, this is useful for reproducibility.
Add a variable name PKG_TIMESTAMP that take a epoch time and set SOURCE_DATE_EPOCH
to this. By default it is the current time so no changes here.
- Convert panic() calls to INVARIANTS-only assertions. The PCTRIE code
provides some of the same protection since it will panic upon an
attempt to remove a non-resident buffer.

The routine is called on successful write and read, which on pipes happens a
lot and for small sizes.
Precision provided by default seems way bigger than necessary and it causes
problems in vms on amd64 (it rdtscp's which vmexits). getnanotime seems to
provide the level roughly in lines of Linux so we should be good here.

Note the that atime handling for named pipes is broken with and without the
patch. The filesystem code is never used for updating atime and never looks
at the updated field. Consequently, while there are no provisions added to
handle named pipes separately, the change is a nop for that case.
