Allow building with either giflib 4.2 or 5.0

Turn off -Werror for Clang 3.5+ and revert r374780 for now.

Add an upstream patch to remove adlc's unused class FileBuffRegion.

Replace USES=libtool:oldver with USES=libtool or USES=libtool:keepla in
the 32 ports that still use it.  Bump PORTREVISION on their dependent
ports except the ones that depend on these:

audio/libogg
audio/libvorbis
devel/pcre
ftp/curl
graphics/jpeg
graphics/libart_lgpl
graphics/tiff
textproc/expat2
textproc/libxslt

In these cases the same trick as in the recent gettext update is used.

Merge Linux-specific changes to BSD patches.  Most importantly, this change
corrects 'os.arch' property for i386 to fix regressions.

The MAP_NORESERVE flag to mmap() has never been implemented in FreeBSD and
is being removed.  No portrev bump needed since the kernel will continue to
accept this flag for old binaries even after support for it in new binaries
is removed.

Fix build with gmake 4.1

. Don't hardcode /bin/bash.  Fixes build trace output.

. Introduce a DIST_BUILD_NUMBER variable and refer to that in both DISTNAME
  and MASTER_SITES.  This fixes the download URL. [1]
. Add a dependency on fontconfig. [2]

. Update to 8u11.  This requires moving the patch file for 8u5 to start
  with 8u05 to preserve patch file ordering.

Implement current and signal methods for sun.nio.ch.NativeThread.  Note this
fixes a test case in the following Apache Solr bug report.

Fix printing services.  When CUPS is used, ${LOCALBASE}/bin/lpr must be used
to print a generated PostScript file.  When lpd(8) is used, lpr(1) from base
must be used.  Also, status command for lpc(8) requires a printer name.  If
no argument is specified, i.e., "/usr/sbin/lpc status", then it displays the
command usage, i.e., "usage: status  {all | printer ...}".  Unfortunately,
"usage" is interpreted as a printer name because ":" is included.  Add "all"
and adjust an expression for grep(1).

Always link libjli statically.  When launchers are symlinked, it may not be
able to find libjli.so from RPATH because argv[0] points to the symlink.
Note it seems Linux does not have the problem when /proc/self/exe exists.
If it does not exist, it also fails to find libjli.so.  Clean up patches
while I am here.

Add support for java/icedtea-web.  Clean up some patches while I am here.

Add a slave port to create JRE-only package for java/openjdk8.

Merge more HotSpot patches from java/openjdk6 and clean up.

- Unbreak libnet.  Obviously, bsd_close.c must not be excluded for BSD.
- Move jspawnhelper to jre/lib/<arch> directory as Solaris does. [1]
- Add sigset(2) wrapper for libsig.so.
- Disable UseMembar by default.

Add couple of patches missed in the previous commit.

Merge more patches for JDK from java/openjdk6 and clean up.

- Disable ccache.  Precompiled headers seem to cause troubles with it. [1]
- Add more BSD patches for Java files and fix endianness issues for C files.

Update to 8u5.

The FreeBSD x11@ and graphics team proudly presents
a zeising, kwm production, with help from dumbbell, bdrewery:

NEW XORG ON FREEBSD 9-STABLE AND 10-STABLE

This update switches over to use the new xorg stack by default on FreeBSD 9
and 10 stable, on osversions where vt(9) is available.
It is still possible to use the old stack by specifying WITHOUT_NEW_XORG in
/etc/make.conf .
FreeBSD 8-STABLE and released versions of FreeBSD still use
the old version.
A package repository with binary packages for new xorg will
be available soon.

This patch also contains updates of libxcb and related ports, pixman, as well

Fix build on 8.3.  We still have to support it for few more weeks.

- Fix a typo, which may add an unnecessary run-time dependency.
- Prefer PKGNAMESUFFIX to deprecated LATEST_LINK.
