If the `setlocale()` call fails, emit a warning and sleep briefly so the
user has a chance to see the warning before we redraw the screen. Note
that we have no way of knowing exactly what is wrong, but at least we
can suggest that they check their environment.

I very occasionally see test failures caused by the total CPU time being
several milliseconds under 3s. The test runs "limits -t 3 time <busy
loop>" and verifies that the reported time elapsed is at least 3s (and
not too much more). In particular, any time spent executing time(1)
itself is counted against the limit but not recorded in the output.
I think it makes more sense to reverse the order, so that the CPU time
limit is not applied to time(1) itself. This also resolves the test
failures I was seeing, which were reproducible only under load (i.e.,
running many tests in parallel).

Tracking newer versions of C (and C++) permits assuming newer language
features in the base system. Some C11 extensions are already used in
the base system but implemented on top of GNU C extensions such as
_Alignas and _Static_assert. In some cases the fallback versions in
cdefs.h are more limited than the native C11 extensions.
Even though C11 is the next major version of C, C17 is chosen instead
since C17 does not add new features to C but merely fixes defects in
C11. It is also well supported by a wide range of clang (7.0.0+) and
GCC (8.1+) versions.
Along with changing the default, this change also removes explicit
requests for c11 via the CSTD variable in various Makefiles.
Libraries and binaries for ZFS continue to use c99.

The uncommented #ifdef _KERNEL originates from 1997 by wollman@ (see
57bf258e3d) with no clear original reason. Since these old times two
abusers of the header leak were created - libprocstat(3) and netstat(1).
These two already have a lot of _WANT_FOO hacks, so satisfy them with
_WANT_PROTOSW.
While here, cleanup and sort forward declaraions.
The file obtains some kernel structures in a dirty way and needs
forward declaration of struct sockopt for that. Make it explicit
instead of getting it via headers that were not designed for that.
Use a separate file for the RPC parser. Potentially it may get bigger.
Also to avoid include RPC header pollution of the genl.c.

People are often stunned by robust manual search functionality on

+ explain what search related flags do instead of using similies
+ consolidate and standardize search options in synopsis and usage
+ mention that a page or file can be specified in synopsis and example
+ call regular expressions `expression`, which searches to re_format(7)
+ crossreference the regular expression manual instead of egrep(1)
+ improve MANPATH xref flow and explanation, matching MAILPATH in sh(1)
+ mark up aditional semantics for their inclusion in apropos

+ use consistent spacing and form (Ql) for quoted literals
+ clean a few linter errors regarding self xref and nospace

install's -o and -g flags both accept a name or a numeric argument.
In -U -M (non-root METALOG) mode it always emitted uname= and gname= in
the METALOG, but these are not appropriate for numeric IDs.
If the -o and/or -u arguments parse as an ID, emit uid= and/or gid=
respectively.
Note that if an argument is valid as both a name and numeric ID we will
prefer the name in normal (non -U -M) mode and the ID in -U -M mode. We
don't want to require a passwd db in non-root mode, and entirely-numeric
user or group names are a terrible idea so just accept this discrepancy.

This program has two modes: monitor a single family and dump known
families. The former uses directly snl_get_genl_family_info() which uses
supposedly internal struct _getfamily_attrs as the argument. The latter
uses a parser named genl_family_parser that makes a mixture of local
definitions and definitions from <netlink_snl_generic.h>. While the
struct genl_family_parser is local, it points at struct
snl_genl_ctrl_mcast_groups and struct snl_genl_ctrl_mcast_group that are
supposedly private to netlink_snl_generic.h, as are hanging off the
underscored _getfamily_attrs.
Rewrite this mess by using same parser for both modes, that is fully
implemented locally. This parser has another very important difference to
the one declared in the header library. It will copy strings out of the
message into memory allocated within the snl_state. With the header
library parser strings point into received packet and contents will be
overwritten on next netlink message. This is not a bug with existing
genl(1) program, but it would be with future changes.
