mdoc: avoid unterminated quoted strings.

Minor indentation and paragraph nits.

Remove superfluous paragraph macro.

Globally replace u_int*_t from (non-contributed) man pages.

The reasoning behind this, is that if we are consistent in our
documentation about the uint*_t stuff, people will be less tempted to
write new code that uses the non-standard types.

I am not going to bump the man page dates, as these changes can be
considered style nits. The meaning of the man pages is unaffected.

mdoc: drop redundant .Pp and .LP calls

They have no effect when coming in pairs, or before .Bl/.Bd

Add capability to use a db version of services. It is enabled by
specifying `db' as source of service in /etc/nsswitch.conf.

Docuemnt exactly which functions access which NSS databases.

Point out that FreeBSD libc has compat stubs for GNU glibc NSS
modules which access NSDB_PASSWD/NSDB_GROUP, but not NSDB_HOSTS;
based on painful experience porting nss_mdns.

Fixed troff(1) and mdoc(7) warnings.

= Implement name service switch modules (NSS modules). NSS modules
may be built into libc (`static NSS modules') or dynamically loaded
via dlopen (`dynamic NSS modules'). Modules are loaded/initialized
at configuration time (i.e. when nsdispatch is called and nsswitch.conf
is read or re-read).

= Make the nsdispatch(3) core thread-safe.

= New status code for nsdispatch(3) `NS_RETURN', currently used to
signal ERANGE-type issues.

= syslog(3) problems, don't warn/err/abort.

= Try harder to avoid namespace pollution.

= Implement some shims to assist in porting NSS modules written for
the GNU C Library nsswitch interface.

mdoc(7) police: Use the new .In macro for #include statements.

Remove whitespace at EOL.

Eliminate mdocNG warnings caused by misplaced or extraneous macro calls.

Prepare for mdoc(7)NG.

Add nsswitch support. By creating an /etc/nsswitch.conf file, you can
configure FreeBSD so that various databases such as passwd and group can be
looked up using flat files, NIS, or Hesiod.

= Hesiod has been added to libc (see hesiod(3)).

= A library routine for parsing nsswitch.conf and invoking callback
functions as specified has been added to libc (see nsdispatch(3)).

= The following C library functions have been modified to use nsdispatch:
. getgrent, getgrnam, getgrgid
. getpwent, getpwnam, getpwuid
. getusershell
. getaddrinfo
. gethostbyname, gethostbyname2, gethostbyaddr
. getnetbyname, getnetbyaddr
. getipnodebyname, getipnodebyaddr, getnodebyname, getnodebyaddr

= host.conf has been removed from src/etc. rc.network has been modified
to warn that host.conf is no longer used at boot time. In addition, if
there is a host.conf but no nsswitch.conf, the latter is created at boot
time from the former.
