more NBUILDJOBS deprecation

The NBUILDJOBS option was deprecated in 2002;
there's no need to keep warning about it,
remove from params / show-params,
and only document as obsolete.

build.sh: add show-params operation

Add show-params operation to the makefile target, and reword
params operation to describe what it's done since 2012.

build.sh: add show-params operation

Add show-params operation to the makefile target, and reword
params operation to describe what it's done since 2012.

(In 2012-11-04 the Makefile's previous params target was renamed
to show-params and a new params target was added to save a 'params'
file, and build.sh wasn't adapted.)

Remove support for building extsrc/:
1. Makefile: remove do-extsrc target.
2. build.sh: remove options -y and -Y extsrcdir.
3. distrib/sets: remove support for extsrc in various tools
including the options -L ext and -y, and the extsrc sets.
4. doc/BUILDING.mdoc: remove docs for extsrc/, EXTSRCSRCDIR, MKEXTSRC (etc)
5. bsd.own.mk and various Makefiles: remove support for extsrc/,
EXTSRCSRCDIR, MKEXTSRC.

As proposed on tech-kern and tech-userlevel on 2022-01-07
and followed up on 2022-08-21.

Makefile: fix location of postinstall program for MAKEVERBOSE > 2

If MAKEVERBOSE > 2, each shell command from a make target is echoed.
This resulted in two additional words ending up in the variable
_POSTINSTALL. Noticed by Brad Harder.

Before:
$ make -v _POSTINSTALL MAKEVERBOSE=3
echo .../usr.sbin/postinstall .../usr.sbin/postinstall/postinstall ...

After:
$ make -v _POSTINSTALL MAKEVERBOSE=3
.../usr.sbin/postinstall/postinstall ...

Enhance the support of LLVM sanitizers

Define _REENTRANT for MKSANITIZER build. This is needed for at least stdio
code. This caused new build issued with duplicated symbols in few places
and rump kernel code picking different code paths borrowed from libc.
Handle all this in one go.

Add bsd.sanitizer.mk to share common code used by programs and libraries.

Switch from realall to beforeinstall target in .syms files. This is more
reliable in MKSANITIZER.

Correct the build rules of LLVM sanitizers

Fix generation of .a.syms files in LLVM sanitizers. The old rules weren't
functional and sometimes they were fatal in the build.

Add the .a.syms files to distribution sets.
These files are generated only in certain .a files in 64bit version of
sanitizers.

Correct the location of files with LLVM sanitizers. Move the LLVM sanitizer
entries from base to comp files.

With the above changes MKOBJDIR is now respected properly for me.

Enhance MKSANITIZER support

Add i386 support for LLVM sanitizers.

Add new build phases do-sanitizer-* for building LLVM sanitizers after libs
and before other programs. This phase is important as sanitizers need
to link with libs and sanitized programs must link with sanitizer runtimes.
