ipifunc[]: Comment IPI constant names for grep'ability.  Constify.
KNF.
Use correct type encoding for DWARF EH on ARM
Rationalize README file handling:
1.) Install only README files that are relevant to the Postfix binaries
    distributed with NetBSD.
2.) Create a single list of the above files that is used for both the
    text versions and HTML versions.

Problem detected by wizd(8).
Update list of Postfix README files.
Sync wizd's feature list with reality.
Don't return ENETRESET when ioctl SIOCSIFMTU

Otherwise, just changing MTU with ifconfig shows
a confusable error message.

Restrict -mno-fp-ret-in-387 to GCC.
The lua 5.1 to 5.3 update added isprint to libkern.h
Keep countries in sync with IATA listings.  NetBSD is not in the business
of defining in which country an airport is.
amend the new destroy function to take function pointers.
use hdestroy1 now that hdestroy does not free the key.
Mark #endifs that are far enough away from their corresponding #ifs to
be unclear.
Try to fix the build:
There is no "AAAREADME.html". So only attempt to install the ASCII version.

Not sure why my full build didn't catch this problem. Sorry.
There is also no HTML version of "RELEASE_NOTES".

Add a callback to change the regulator outputs.
Tested on beaglebone.
am335x: expect the board code to provide a set_mpu_volt() function,
to change the MPU code voltage. When changing MPU frequency also request
a voltage change. provide frequency/voltage tables for the "blank" revision
and de A revision, based on documents from www.ti.com (this means
it's not possible anymore to request a beaglebone white to run at 1Ghz,
but this was not working anyway).
beagle_machdep.c: callback to the tps65217pmic to change the MPU voltage.

Tested on beaglebone, from 275 to 720Mhz, and on beaglebone black from
300 to 1000Mhz.
Adjustments based on suggestions from gnrp in PR 45276:
 - fix argument names of VOP_REMOVE
 - mention deprecated behavior of calling VOP_GETATTR unlocked
 - mention rename lock
Don't assume if_init is always set

if_init may be NULL, e.g., if_vlan.
