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

lang/fpc: Fix build issues building some fpc based apps

- Add missing parameter to getdirentries syscall function
- Re-build i386 and amd64 bootstrap
- Revert fpc-i386 (FPC_USE_LIBC) build to syscall build
- Bump PORTREVISION in all ports dependant of freepascal compiler

lang/fpc-*: Update bootstrap to 3.2.2

- Update i386 and amd64 bootstrap to 3.2.2
- Fix issues with new stat struct
- Now i386 is build using FPC_USE_LIBC
- Fix build on i386 when FPC_USE_LIBC is used
- Update fpc source code to newer kernel syscalls. It removes COMPAT11

textproc/libxml2: bump all dependencies

This should make sure that all dependent ports will pick
up the new version commited with a13ec21cd733f67a9fc0dc00ab45268bdc236246

Remove # $FreeBSD$ from Makefiles.

- Migrate Mk/bsd.fpc.mk to Mk/Uses/fpc.mk
- Convert all fpc-based ports to USES=fpc

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

- editors/lazarus update to 1.4.2
- Add USE_FPC_RUN to bsd.fpc.mk. It add fpc units like run dependencies.
Otherwise
  fpc units only are added like build dependencies (less dependencies registered
  when they are installed with pkg).
- Remove GTK1 obsolete dependencies
- Bump all ports with dependencies of fpc-* units
- Bump all ports with dependencies of lazarus ports
- Clean up

Assign maintainership of FPC ports to new FPC ports team

The new team currently consists of the previous maintainer (acm@) and
myself (marino@).

Cleanup plist

Stage support

Add NO_STAGE all over the place in preparation for the staging support (cat:
textproc)

- adopt optionsNG and trim historical headers
