lang/fpc-*: Merge all units to lang/fpc

- Merge all fpc-* units to lang/fpc. It gives us a better way to maintain fpc
  and lazarus ports.
- Update Mk/fpc.mk for reflects new changes
- Update Mk/lazarus.mk for reflects new changes
- Now we can defined WANT_FPC_DEVEL AND WANT_LAZARUS_DEVEL for use devel version
  of fpc or lazarus for build apps based on fpc/lazarus
- Add entries to MOVED
- Bump PORTREVISON of affected ports
- Some other minor modifications

One more small cleanup, forgotten yesterday.

Remove # $FreeBSD$ from Makefiles.

- Update to 3.2.0

ChangeLog at:	https://wiki.freepascal.org/FPC_New_Features_3.2.0

- Remove compat < 11 dependencies from bootstrap and compiler. It could fix
problems
  when GENERIC kernel is not used.
- Rebuild bootstrap (ppcx64 and ppc386) with new changes
- Bump PORTREVISION

- Change LDPATH to FPC_LDPATH into lang/fpc/Makefile. It can be changed from
  /etc/make.conf
- Add FPC_LDPATH to freepascal compiler. By default it is defined to
  %%LOCALBASE%%/bin/ld.bfd but it can be changed setting FPC_LDPATH environment
  variable
- Remove compatX dependencies from bootstrap and compiler. It could fix problems
  when GENERIC kernel is not used [1]
- Rebuild bootstrap (ppcx64 and ppc386) with new changes
- Bump PORTREVISION

Submitted by:	fbsdbugs4 __at__ sentry.org

- Rebuild bootstrap (ppcx64 and ppc386) with ld patches
- Fix build on 12-STABLE and CURRENT (amd64 and i386)
- Bump PORTREVISION for all ports that depends of lang/fpc
- Add USE_BINUTILS to fpc and lazarus based ports
- Add binutils dependency to Uses/fpc.mk and Uses/lazarus.mk

- Add new fpc bootstrap (i386 and x86_64). It could need less COMPATX
  dependencies in kernel
- Add patch file to solve some linking problem
- Remove LD_UNSAFE. Now it can be defined via LDPATH (/usr/bin/ld.bfd by
  default). fpc is not working with lld. We will use binutils-ports when
  ld.bfd is moved from base if lld not working on future version
  of fpc
- Bump PORTREVISION

Bump PORTREVISION for ports depending on the canonical version of GCC
as defined in Mk/bsd.default-versions.mk which has moved from GCC 8.3
to GCC 9.1 under most circumstances now after revision 507371.

This includes ports
 - with USE_GCC=yes or USE_GCC=any,
 - with USES=fortran,
 - using Mk/bsd.octave.mk which in turn features USES=fortran, and
 - with USES=compiler specifying openmp, nestedfct, c11, c++0x, c++11-lang,
   c++11-lib, c++14-lang, c++17-lang, or gcc-c++11-lib
plus, everything INDEX-11 shows with a dependency on lang/gcc9 now.

FPC ecosystem: Upgrade version 2.6.4 => 3.0.0

This is the first major release of FreePascal in nearly four years.
There are a ton of new features, way more to list here. see:
http://wiki.freepascal.org/FPC_New_Features_3.0

Several new unit ports were added, some were contracted.  Most of
those were absorbed into the main FPC packages, but two units are
no longer supported: sndfile and matroshka.

All 99 remaining ports (including Lazarus ports) were build tested
on FreeBSD i386 and amd64 Release 10.2
