share/examples: clarify BOOT_COMCONSOLE_SPEED

Give an example of why one may want to override BOOT_COMCONSOLE_SPEED so
that it's clear why the default (in a comment) and the commented-out
example setting have different values.

Reported by: otis
Fixes: 4722ceb7d53e ("Use 115200 bps by default for serial communication")

Use 115200 bps by default for serial communication

9600 was a standard baud rate decades ago, but 115200 is now more common
so choose defaults that are useful to the largest number of users.

Note that boot0sio does not support rates above 9600 so it remains
unchanged.

Tidy up bsd.cpu.mk for X86 CPUs:

- Do not limit recent processors to "prescott" class for i386 target. There
is no reason for this hack because clang is default now. On top of that, it
will only grow indefinitely over time.
- Add more CPUTYPEs, i.e., "athlon-fx", "core-avx2", "atom", "penryn", and
"yonah". Note "penryn" and "yonah" are intentionally undocumented because
they are not supported by gcc and marked deprecated by clang.
- Add more CPUTYPE aliases, i.e., "barcelona" (-> amdfam10), "westmere" and
"nehalem" (-> corei7). Note these are intentionally undocumented because
they are not supported by (base) gcc and/or clang. However, LLVM (backend)
seems to "know" the differences. Most likely, they were deprecated with
other vendor code names and clang did not bother implementing them at all.
- Add i686 to MACHINE_CPU for "c3-2" (VIA Nehemiah). Both gcc & clang treat
it like an i686-class processor.
- Add IDT "winchip2" and "winchip-c6" for completeness (undocumented).
- Order processors per make.conf example, i.e., CPU vendors and models.
- Tidy up make.conf example, i.e., remove "by gcc" (because we have aliases)
and remove "prescott" from AMD64 architecture (because it is not correct).

Remove fictitious support for 80386-class CPUs from bsd.cpu.mk and make(1).

Take -Wconversion out of BDECFLAGS. It is not particularly useful for

space. However, the x86 abi that we use *does* promote to 32 bit,
and the alpha ABI passes them in 64 bit registers so we dont have
that aspect of the problem here. Losing float precision by having it
cast down to int because the funtion prototype specifies int is the
least of our problems. -Wmissing-prototypes helps here anyway.

Need one additional make.conf knob, SENDMAIL_ADDITIONAL_MC to satisfy bug
report. It allows building multiple .cf files at build time.

PR: bin/19897

Add a note indicating that SENDMAIL_MC should include the path. This is
necessary if you expect to be able to use this setting in both /etc/mail
and etc/sendmail.

Overhaul the MACHINE_CPU behaviour:

* Rip out MACHINE_CPU stuff from sys.mk and include a new <bsd.cpu.mk>
after we pull in /etc/make.conf. We need to do it afterwards so we can
react to the user setting of the:

* CPUTYPE variable, which contains the CPU type which the user wants to
optimize for. For example, if you want your binaries to only run on an
i686-class machine (or higher), set this to i686. If you want to support
running binaries on a variety of CPU generations, set this to the lowest
common denominator. Supported values are listed in make.conf.

* bsd.cpu.mk does the expansion of CPUTYPE into MACHINE_CPU using the
(hopefully) correct unordered list of CPU types which should be used on
that CPU. For example, an AMD k6 CPU wants any of the following:
k6 k5 i586 i486 i386
This is still an unordered list so the client makefile logic is simple -
client makefiles need to test for the various elements of the set in
decreasing order of priority using ${MACHINE_CPU:M<foo>}, as before.
The various MACHINE_CPU lists are believed to be correct, but should be
checked.

* If NO_CPU_CFLAGS is not defined, add relevant gcc compiler optimization
settings by default (e.g. -karch=k6 for CPUTYPE=k6, etc). Release
builders and developers of third-party software need to make sure not to
enable CPU-specific optimization when generating code intended to be
portable. We probably need to move to an /etc/world.conf to allow the
optimization stuff to be applied separately to world/kernel and external
compilations, but it's not any worse a problem than it was before.

* Add coverage for the ia64/itanium MACHINE_ARCH/CPUTYPE.

* Add CPUTYPE support for all of the CPU types supported by FreeBSD and gcc
(only i386, alpha and ia64 first, since those are the minimally-working
ports. Other architecture porters, please feel free to add the relevant
gunk for your platform).

Add a new make knob, SENDMAIL_MC, which is meant to replace SENDMAIL_CF as
users should be configuring via m4 now. If set, use m4 to create the .cf
file. Also, if either SENDMAIL_MC or SENDMAIL_CF is set, 'make install' or
'make distribution' in src/etc/sendmail/ will install the appropriate .cf as
/etc/mail/sendmail.cf. This fixes some mergemaster problems.

PR: conf/13016

Introduce support for using OpenSSL ASM optimizations. This is done
through the use of a new build directive, MACHINE_CPU, which contains a
list of the CPU generations/features for which optimizations are desired.
This feature will be extended to cover the ports tree in the future.

Currently OpenSSL provides optimizations for i386, i586 and i686-class
CPUs. Currently it has not been tested on an i386 or i486.

Teach make(1) to provide sensible defaults for MACHINE_CPU if it is not
defined (namely, the lowest common denominator CPU we support for each
architecture). Currently this is i386 for the i386 architecture and ev4
for the alpha. sys.mk also sets the variable as a last resort for
consistency with MACHINE_ARCH and bootstrapping from very old versions of
make.

Benchmarks show a significant speed increase even in the i386 case, with
additional improvements for i586 and i686 systems. For maximum performance
define MACHINE_CPU=i686 i586 i386 in /etc/make.conf.

Explicitly list the i/o addresses of the serial ports.

Prompted by docs/12343, in which people seemed to get a little confused.
The original text in the file said:

[...]
# By default we use COM1 as our serial console port *if* we're going to use
# a serial port as our console at all. (0x3E8 = COM2)
#
#BOOT_COMCONSOLE_PORT= 0x3F8
[...]

From what I can make out, some people have assumed that means that if
they just uncomment the BOOT_COMCONSOLE_PORT then it will use COM2:
These same people then assume that "0x3F8" on that line is a typo for
"0x3E8".

What it actually means is that if you uncomment the line then the default
stays as "Ox3F8" (COM1:), and that you have to uncomment the line, *and*
change the value of the variable in order to use COM2:.

So I've made that a little bit clearer. I've also listed the hex values
for COM1: thru COM4:, snarfed from sys/isa/isareg.h.
