As reported in PR184149, it can happen that epair devices can have the same
MAC address.
This solution is based on a 32-bit hash, obtained combining the if_index of
the a interface and the hostid.
If the hostid is zero, a random number is used.

Yet another preemption request hitting between the counter being 0

Note the situation was already present prior to r334062 and is harmless.

I'm not quite sure why this wasn't caught before. Most likely due to
some generated file not being properly cleaned.
Fix build by just hiding the warnings that `-i` was supposed to fix.
Tested with clang, gcc9, gcc7
will be returned to indicate the error, so I'm applying an assert(3) to do
a sanity check of the return value.

Rework the README to make it a little easier for new users. This is the
first file many will see when persuing the FreeBSD source code so
- remove some of the text describes how to build. This is better covered
in the linked documentation.
- add a small blurb for what FreeBSD is. Some users might find this
document through features such as github search so they may not even
know what the project is
generally, gear this file for the new, accidental, or casual user rather
than towards someone seeking fuller documentation.
using the appropriate (unsigned) format specification. This prevents
integer overflow when ULLONG_MAX and (on some architectures) ULONG_MAX
are used to initialize an intmax_t and then displayed as the signed
value -1. (A different approach was suggested in the bug report,
which I did not use.) If other limits are defined to be unsigned,
they could be moved here.

When large SPDs are used, we face two problems:
- too many CPU cycles are spent during the linear searches in the SPD
for each packet
- too much contention on multi socket systems, since we use a single
shared lock.
Main changes:
- added the sysctl tree 'net.key.spdcache' to control the SPD cache
(disabled by default).
- cache the sp indexes that are used to perform SP lookups.
- use a range of dedicated mutexes to protect the cache lines.

Rather than using #ifdef's around a static char array, use the
existing helper macro from <sys/cdefs.h> for SCCS IDs. To
preserve existing behavior, add -DNO__SCCSID to CFLAGS to not
