Fix warnings found by -Wmising-variable-declarations.

This self-written compiler warning, which is hopefully going to be
committed into LLVM sources soon, warns about potentially missing
`static' keywords, similar to -Wmissing-prototypes.

- bin/pax: Move external declaration of chdname and s_mask into extern.h.
- bin/setfacl: Move setfacl.c-specific stuff out of setfacl.h.
- sbin/mount_fusefs: Remove char *progname; use getprogname().
- others: add `static' where possible.

Add more static keywords to rcorder(8).

The global variables and functions provided by rcorder.c are not used in
the other C files, as the other C files only provide memory allocation
and hash functions. This reduces the binary size by 10%.

Add missing static keywords for global variables to tools in sbin/.

These tools declare global variables without using the static keyword,
even though their use is limited to a single C-file, or without placing
an extern declaration of them in the proper header file.

ANSIfy almost all applications that use WARNS=6.

I was considering committing all these patches one by one, but as
discussed with brooks@, there is no need to do this. If we ever
need/want to merge these changes back, it is still possible to do this
per application.

Cleanup of userland __P use

do_file() is called recursively from several places and cannot
safely free() anything related to items that may be recursed on.

This commit was generated by cvs2svn to compensate for changes in r98567,
which included commits to RCS files with non-trunk default branches.

Sync with NetBSD.
* don't whine about non-regular files. It is perfectly normal to keep a
CVS or RCS directory in /etc/rc.d.
* manpage tweak

Import the NetBSD 1.5 RC system.

Note that `rc' and `rc.shutdown' could not be imported because we already
have files with those names.
