bsd.*.mk: move MKSTRIPSYM default to bsd.own.mk

Add default for MKSTRIPSYM=yes to to bsd.own.mk _MKVARS.no.
Test ${MKSTRIPSYM} != "no".

Resolve conflicts for lua 5.4.4 import.
Adjust various files for lua 5.4.4.

Introduce MKSTRIPSYM build option

If it's yes, all local symbols of shared libraries are stripped
(default). If it's no, only temporary local symbols are stripped;
for example, symbols of static functions are kept. Keeping such
symbols is useful on using DTrace for userland libraries and
getting a backtrace from a rump server loading modules (shared
libraries).

Proposed and discussed on tech-kern and tech-toolchain

branches: 1.7.6; 1.7.10;
lua: updated from 5.1 to 5.3 work3

* lua(1):
- changed lua_Integer to intmax_t
- updated distrib/sets/lists and etc/mtree
- updated bsd.lua.mk
- fixed bozohttpd (lua-bozo.c)
- compatibilized bindings: gpio, sqlite
* lua(4):
- removed floating-point and libc dependencies using '#ifndef _KERNEL'
- fixed division by zero and exponentiation
- libkern: added isalnum(), iscntrl(), isgraph(), isprint() and ispunct()
- acpica: removed isprint() from acnetbsd.h
- libc: moved strcspn.c, strpbrk.c and strspn.c to common
- removed stub headers
- compatibilized bindings: luapmf, luasystm
* reorganized luaconf.h
* updated doc/CHANGES and doc/RESPONSIBLE

branches: 1.6.2;
Pass PICFLAGS down to cc-as-as and use __PIC__ to decide if it is small
vs big PIC mode. Retire -DPIC and -DBIGPIC.

If a library needs a symbol from another library, pull that library in
explicitly, even if the DT_NEEDED closure would normally already ensure
the presence.

branches: 1.4.2; 1.4.8;
Uncomment LUA_DPLIBS processing, but do not auto-include liblua.so,
under the assumption that programs that load Lua modules already have
loaded it.

Comment out the '##### Libraries that modules may depend upon.' for now,
so that modules written in C can be built.

Use bsd.clean.mk instead of defining our own "clean" target.
