init(8) sets the "daemon" login class without specifying a pw
entry (so no substitutions are done on the variables). service(8)'s
use of env -L had the effect of specifying root's pw entry, with two
effects: getpwnam and getpwuid are being called, which may not be
entirely safe depending on what nsswitch is up to and what stage of
boot we are at, and substitutions would have been done.
Fix by teaching env(8) to allow -L -/classname to set the class
environment with no pw entry at all specified, and use it in
service(8).

This allow us to create image with the following format:
mkimg -v -o sdcard -s gpt -p efi:=esp_aarch64.img:1M -p freebsd-ufs::1G
Which will add a efi partition at a 1M offset on the image with its content
coming from the esp_aarch64.img file.
MFC after: 3 days
Even with an absolute offset we want to know the last block the partition
otherwise we endup with an image the size of the metadata.
This allow to create image with the ESP placed at a specific position which
is useful on arm/arm64 where u-boot have always a hard time to read the ESP
if it's not aligned on 512k.

Along with the termcap database, ncurses will now lookup for the
terminfo database, note that the terminfo database is being looked
up first and then it fallsback on the termcap one.
While here drop our custom reader for the termcap database, over the
time it is needed maintenance to be able to catchup with changes on ncurses
side.
Install the ncurses tools which are needed to deal with the terminfo
database: tic, infocmp, toe
Replace our termcap only aware tools with the ncurses counterpart:
tput, tabs, tset, clear and reset
In particular they can your the extra capabilities described in the
terminfo database, which does not exist in termcap
Note that to add a new terminfo information to the database from ports
the ports will just need to add their extra information into:
/usr/local/share/site-terminfo/<firstletteroftheterm>/<term>

working copy format is still the same as Subversion 1.8 through 1.13.
NOTE 2: The upstream release also contains a fix for a security issue in
mod_dav_svn (CVE-2020-17525), but since we do not build or use any
Apache modules, it is not an issue for the FreeBSD base system.

Glibc's stdlib.h defines various prototypes for GNU extensions that take
a locale_t. Newer versions use locale_t directly and include an internal
bits/types/locale_t.h in order to get its definition, but older versions
include xlocale.h for that, for which our bootstrap version is empty.
Moreover it expects to use the glibc-specific __locale_t type. Thus,
provide dummy definitions of both types in order to ensure the
prototypes don't give any errors, and guard against the header being
inadvertently included between the bootstrapping namespace.h and
un-namespace.h, where locale_t is #define'd.
This header is not used when bootstrapping on FreeBSD and exists solely
to stub out glibc's, so this should have no impact on FreeBSD hosts.

The basic issue here is that grep, when given -m 1, would stop all
line processing once it hit the match count and exit immediately. The
problem with exiting immediately is that -A processing only happens when
subsequent lines are processed and do not match.
The fix here is relatively easy; when bsdgrep matches a line, it resets
the 'tail' of the matching context to the value supplied to -A and
dumps anything that's been queued up for -B. After the current line has
been printed and tail is reset, we check our mcount and do what's
needed. Therefore, at the time that we decide we're doing nothing, we
know that 'tail' of the context is correct and we can simply continue
on if there's still more to pick up.
With this change, we still bail out immediately if there's been no -A
flag. If -A was supplied, we signal that we should continue on. However,
subsequent lines will not even bothere to try and process the line. We
have reached the match count, so even if the next line would match then
we must process it if it hadn't. Thus, the loop in procfile() can
short-circuit and just process the line as a non-match until
procmatches() indicates that it's safe to stop.
A test has been added to reflect both that we should be picking up the
next line and that the next line should be considered a non-match even
if it should have been.

The null pattern semantics were terrible because I tried to match gnugrep,
but I got it wrong. Let's unwind that:
- The null pattern should match every line if neither -w nor -x.
- The null pattern should match empty lines if -x.
- The null pattern should not match any lines if -w.
The first two will stop processing (shortcut) even if additional patterns
are specified. In any other case, we will continue processing other
patterns. If no other patterns are specified beside a null pattern, then
we match if neither -w nor -x or set and do not match if either of those
are specified.
The justification for -w is that it should match on a whole word, but the
null pattern deos not have a whole word to match on.
Empty pattern files should never match anything, and more importantly, -v
should cause everything to be written.

note to determine if an ELF shared library without OSABI set in the

When diff hits certain access errors, function diffreg() shows the error
message, and then returns to the calling function, which calls
print_status() with the return value.
However, in these cases, the return value isn't changed from the initial
default value of D_SAME.
Normally, print_status() with a value of D_SAME does nothing, so this
works out ok, however, if the "-s" flag is set, a message is displayed
showing identicality:
case D_SAME:
if (sflag)
printf("Files %s%s and %s%s are identical\n", path1, entry, path2, entry);
break;
This then produces such results as:
% diff -s /COPYRIGHT /var/run/rpcbind.sock
diff: /var/run/rpcbind.sock: Operation not supported
Files /COPYRIGHT and /var/run/rpcbind.sock are identical
% diff -s /COPYRIGHT /etc/master.passwd
diff: /etc/master.passwd: Permission denied
Files /COPYRIGHT and /etc/master.passwd are identical
Create a D_ERROR status which is returned in such cases, and
print_status() then deals with that status seperately from D_SAME
