build/jam: Only add C++ header directories to include path for C++ code.

There are now some system headers (e.g. <stdatomic.h>) that have outright
different versions for C and C++ which are not compatible with each other.

jam/HeaderRules: Put posix before gcc

* After the gcc 8 upgrade, during bootstrap sources attempt to
load limits.h from gcc before they use our limits.h override
resulting in undefined NAME_MAX, PATH_MAX, etc.

Revert the Codec Kit.

All of Barrett's individual reverts have been squashed into this
one commit, save a few actual bugfixes.

Change-Id: Ib0a7d0a841d3ac40b1fca7372c58b7f9229bd1f0

codec_kit: First half

* Move all codec stuff into libcodec.so

build: Copy and use Clang's vector intrinsics headers.

When compiling with GCC, these headers get pulled in from the
gcc_syslibs_devel package, but we cannot do something similar
for Clang as Clang adds/removes internal builtins used by
the headers nearly every version. So instead we just copy
all the intrinsics headers from current Clang into generated,
and make sure this directory is included before any others.

Cleanup with respect to headers rules.

* Move specialcasing of gcc2 from HeadersRules into the respective rule
in SystemLibraryRules.

* When using the non-legacy compiler, use the c++ and gcc headers
provided in the gcc_syslibs_devel build feature for building Haiku.
* Simplify declaration of c++ and gcc headers for the legacy compiler -
in the end we always use the ones living by our source tree anyway.
* Fix a couple of missing local declarations for jam variables, which
were necessary to avoid a build problem with strace. There are
probably more bugs like these hiding in our build system files, but
I'm saving the fix for those to the next commit.
* Add new gcc packages to the HaikuPorts (x86*-)repositories.

Whitespace cleanup in root and 'build' folder.

* Removed trailing whitespace and empty lines at top of files.

GL: Remove OpenGL kit, x86 Mesa

* Depend on Mesa packages to provide functionality

More work towards hybrid support

* All packaging architecture dependent variables do now have a
respective suffix and are set up for each configured packaging
architecture, save for the kernel and boot loader variables, which
are still only set up for the primary architecture.
For convenience TARGET_PACKAGING_ARCH, TARGET_ARCH, TARGET_LIBSUPC++,
and TARGET_LIBSTDC++ are set to the respective values for the primary
packaging architecture by default.
* Introduce a set of MultiArch* rules to help with building targets for
multiple packaging architectures. Generally the respective targets are
(additionally) gristed with the packaging architecture. For libraries
the additional grist is usually omitted for the primary architecture
(e.g. libroot.so and <x86>libroot.so for x86_gcc2/x86 hybrid), so that
Jamfiles for targets built only for the primary architecture don't
need to be changed.
* Add multi-arch build support for all targets needed for the stage 1
cross devel package as well as for libbe (untested).

Add more rules to simplify dealing with build features

* Introduce the notion of build feature attributes and add rules
SetBuildFeatureAttribute and BuildFeatureAttribute to set respectively
get a build feature attribute.
* Add rule ExtractBuildFeatureArchives to download and extract archives
and set build feature attributes to extracted entries.
* Add rule UseBuildFeatureHeaders as a shorthand for getting a build
feature attribute and adding it as a system header search directory.

Added PrivateBuildHeaders and UsePrivateBuildHeaders rules.

* reintegrated gsoc-locale-kit branch into trunk - there's more
work to do, but it's about time to give this code more exposure.



git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33176 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Moved termcap.h to headers/libs/termcap/, where it belongs.
* Removed the headers/gnu from the default headers (the Jamfiles needing it
use it explicitly, now) and moved it under headers/compatibility/.
* Added libgnu.so to the image. Still untested, though.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32481 a95241bf-73f2-0310-859d-f6bbb57e9c96

Move include directories for C++ headers to the beginning. This makes
include_next work properly with newer headers. GCC 4.3.2 has a <cstddef> in its
C++ headers for example that does an include_next of <stddef.h>. The latter is
located in the C headers. For this to work, the include directory for the C
headers needs to be specified later than the one of the C++ headers.
With that Haiku is now completely buildable with GCC 4.3.2.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@28995 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Introduced new header directory headers/private/system which is supposed
to contain headers shared by kernel and userland (mainly libroot).
* Moved quite a few private kernel headers to the new location. Split
several kernel headers into a shared part and one that is still kernel
private. Adjusted all affected Jamfiles and source in the standard x86
build accordingly. The build for other architectures and for test code
may be broken.
* Quite a bit of userland code still includes private kernel headers.
Mostly those are <util/*> headers. The ones that aren't strictly
kernel-only should be moved to some other place (maybe
headers/private/shared/util).

Second stab at reorganizing standard/gcc headers. This time it not only
builds on Linux with gcc 2 and 4, but the images do even run. :-) Not
tested on BeOS.

* Removed stddef.h and stdarg.h. They are provided by the compiler.
* Adjusted size_t.h, wchar_t.h, and wchar.h accordingly.
* Made stdio.h avoid gcc 2.95.3's fixincludes hack stdio_va_list
* Added gcc 2.95.3 headers to the repository. They are used instead of
the headers of the gcc 2.95.3's we use to compile Haiku with. Should
avoid build problems with the BeOS native compiler.

For sake of personal recreation you can rebuild the cross gcc 2.95.3,
but the only thing that changed is its header directory
(lib/gcc-lib/.../include), which isn't used anymore. Replacing it with
headers/build/gcc-2.95.3 should have the same effect as rebuilding, BTW.

Reverted r24406. If it builds, it doesn't always work as well. The
change resulted in "version mismatch between boot loader and kernel". So
apparently the size of some type changed unintentionally.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@24408 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Removed our stddef.h. We don't need it, since gcc comes with one that
under Haiku overrides ours anyway.
* Adjusted size_t.h, wchar_t.h, wchar.h accordingly. This should fix the
annoying "ssize_t redefined" warnings when compiling under Haiku.
* When building Haiku the gcc headers come first in the include
search path now, as it should be. The respective TODO suggested that
this might break the build depending on compiler version and host
platform. I've tested with Linux gcc 2 and gcc 4, which work fine.

1. Deleted headers/shared/
2. Added a Jamfile to src/shared to build it into a static library libshared.a.
3. Removed my changes in the build/jam directory.
4. Have ShowImage include libshared.a.

I forgot to add AboutWindow.h to headers/private/shared. I will do that next.

Moved the BAboutWindow implementation to the shared source directory, which
despite being talked about repeatedly, does not currently exist.

Adding this required adding some new Jam rules to deal with this shared source
directory and headers. I had some fun figuring this out. Despite writing
articles about Jam in the Haiku newsletter a few years ago I still find Jam to
be a PITA at times.

But my solution seems to work pretty well. Basically you just call the rule
UseSharedSource and pass the name of the shared source file you want to use.
This rule sets up the header directories and the right Jam variables for the
source file. You then add the source file to the source list in the Application
rule like any other source file.

I also made the authors list sent to the about window constructor null
terminated instead of passing the size of the array, as suggested by Hugo.

Introduced new build system features: The variable HAIKU_DONT_INCLUDE_SRC to
turn off the inclusion of src/Jamfile, and the rule DeferredSubInclude to
include a subdirectory in UserBuildConfig. Together they allow a developer
working on a subproject to reduce jam's parsing time when only building the
subproject. Relevant mostly on BeOS; on Linux jam is pretty fast anyway.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20321 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added new (currently private) API class BMimeSnifferAddon,
representing the interface for, well, MIME sniffer add-ons.
* Implemented the respective add-on manager and make use of it in
the MIME database code. Unfortunately the MIME DB code completely
lives in libbe.so and hence I had to put my code there too.
IMHO we should (one day) remove the direct (read-only) MIME DB
access from libbe and move everything into the registrar.
Currently the add-on manager supports built-in add-ons only; it
doesn't really load anything from disk ATM.
* Added a built-in text sniffer add-on to the registrar. It's based
upon the BSD file tool code.

This closes bug #250 (plain text files are identified as such, now).
