libmagicrt: integrate into build system

The magic runtime library is now built as part of the regular build, if
the MKMAGIC=yes flag is passed to the build system. The library has
been renamed from "magic" to "magicrt" to resolve a name clash with BSD
file(1)'s libmagic. All its level-5 LLVM warnings have been resolved.
The final library, "libmagicrt.bcc", is now stored in the destination
library directory rather than in the source tree.

Do not instrument malloc implementation variables

Since the heap is reconstructed upon state transfer, the old malloc
state is discarded. In order to avoid state transfer errors, we can
and in fact must discard the internal state of the malloc
implementation. This patch achieves this by using the sectionify
pass to mark the variables in the libminc malloc object as state that
must be skipped during state transfer.

Experimental pthread compatibility library

This patch adds pthread compatibility by using libmthread.

To use this with a program using pthreads, you have to replace
#include <pthread>
with
#define _MTHREADIFY_PTHREADS
#include <minix/mthreads>

This also changes the initialization function to be a constructor, which
is implicitly called before the call to main. This allows for
conformance with pthreads, while not paying a high price by checking on
each mthread_* call whether the library has been initialized or not.

As mthread_init is now a constructor, it also has been set as static, and
relevent calls removed from programs using it.

- Fix for possible unset uid/gid in toproto
- Fix for default mtree style
- Update libelf
- Importing libexecinfo
- Resynchronize GCC, mpc, gmp, mpfr
- build.sh: Replace params with show-params.
This has been done as the make target has been renamed in the same
way, while a new target named params has been added. This new
target generates a file containing all the parameters, instead of
printing it on the console.
- Update test48 with new etc/services (Fix by Ben Gras <ben@minix3.org)
get getservbyport() out of the inner loop

Enable optional GCC install and GCC improvements

-By adding MKGCC=yes and MKGCCCMDS=yes on the make commandline
it is now possible to compile and install GCC on the system.

Before doing this, if you are not using the build.sh script,
you will need to call the fetch scripts in order to retrieve
the sources of GCC and its dependencies.

-Reduce difference with NetBSD share/mk

Move Minix-specific parameters from bsd.gcc.mk to bsd.own.mk,
which is anyway patched, so that bsd.gcc.mk is now aligned
on the NetBSD version.

-Clean libraries dependencies, compiles stdc++ only if gcc is
also compiled (it is part of the gcc sources)

-Correct minix.h header sequence, cleanup spec headers.

-Fix cross-compilation from a 32bit host targeting MINIX/arm

Cross compile on minix support

* Remade patch so it works with minix patch tool.

* New MINIX tar support -ox, so revert back to it

In fetch scripts, tar had been replaced by bsdtar as the prebvious
tar did not support the -o flag under minix, which is required to
prevent usage of tar file stored user and group information.

This introduces portability problems. As our new tar tool now
support that flag revert back to improve portability.

Upgrading build system to new NetBSD revision

The tested targets are the followgin ones:
* tools
* distribution
* sets
* release

The remaining NetBSD targets have not been disabled nor tested
*at all*. Try them at your own risk, they may reboot the earth.

For all compliant Makefiles, objects and generated files are put in
MAKEOBJDIR, which means you can now keep objects between two branch
switching. Same for DESTDIR, please refer to build.sh options.

Regarding new or modifications of Makefiles a few things:
* Read share/mk/bsd.README
* If you add a subdirectory, add a Makefile in it, and have it called
by the parent through the SUBDIR variable.
* Do not add arbitrary inclusion which crosses to another branch of
the hierarchy; If you can't do without it, put a comment on why.
If possible, do not use inclusion at all.
* Use as much as possible the infrastructure, it is here to make
life easier, do not fight it.

Sets and package are now used to track files.
We have one set called "minix", composed of one package called "minix-sys"

build shared versions of libraries

building defaults to off until clang is updated.

current clang does not handle -shared, necessary to change the ld
invocation to build shared libraries properly. a new clang should be
installed and MKPIC defaults to no unless the newer clang is detected.

changes:

. mainly small imports of a Makefile or two and small fixes
(turning things back on that were turned off in Makefiles)
. e.g.: dynamic librefuse now depends on dynamic
libpuffs, so libpuffs has to be built dynamically too
and a make dependency barrier is needed in lib/Makefile
. all library objects now have a PIC (for .so) and non-PIC
version, so everything is built twice.
. generate PIC versions of the compat (un-RENAMEd) jump files,
include function type annotation in generated assembly
. build progs with -static by default for now
. also build ld.elf_so
. also import NetBSD ldd

Full switch to clang/ELF. Drop ack. Simplify.

There is important information about booting non-ack images in
docs/UPDATING. ack/aout-format images can't be built any more, and
booting clang/ELF-format ones is a little different. Updating to the
new boot monitor is recommended.

Changes in this commit:

. drop boot monitor -> allowing dropping ack support
. facility to copy ELF boot files to /boot so that old boot monitor
can still boot fairly easily, see UPDATING
. no more ack-format libraries -> single-case libraries
. some cleanup of OBJECT_FMT, COMPILER_TYPE, etc cases
. drop several ack toolchain commands, but not all support
commands (e.g. aal is gone but acksize is not yet).
. a few libc files moved to netbsd libc dir
. new /bin/date as minix date used code in libc/
. test compile fix
. harmonize includes
. /usr/lib is no longer special: without ack, /usr/lib plays no
kind of special bootstrapping role any more and bootstrapping
is done exclusively through packages, so releases depend even
less on the state of the machine making them now.
. rename nbsd_lib* to lib*
. reduce mtree
