build: Define _BOOT_MODE once and for all in ArchitectureRules+BootRules.

Previously it was spread all around the tree, and was not defined
consistently for all boot objects (there were a number of boot modules
which did not define it, but did include headers which checked for it.)

Now, as it is handled in SetupBoot which is invoked for all boot objects,
it will be applied consistently throughout. We can thus drop the manual
additions of it from all Jamfiles.

system/boot: Add support for multiple bootloaders

bootloader: build objects in $(TARGET_BOOT_PLATFORM)

This separates the objects required for the various boot
loaders, allowing the build system to be able to build
for different targets alongside each other. Currently
only done for bios_ia32 vs efi, as both loaders will be
needed for the x86_64 images.

Setup -fno-pic or -fpic in Architecture Rules.

EFI boot needs -fpic but all boot code was built with -fno-pic.
This is now set accordingly in HAIKU_BOOT_CCFLAGS and
HAIKU_BOOT_C++FLAGS.

Also setup compile flags for EFI platform.

bfs: Use the QueryParserUtils instead of its own copy.

* Ingo copied the methods into a shared location, and then obviously
"forgot" to let BFS use them. As a side note for Ingo: the complete
error GCC reported was "std::fssh_size_t" not defined with the macro
wrapper as code location. The actual problem was a "using std::size_t"
in some C++ header that accidentally got included after the wrapper.
* The shared Query code is not yet used. That'll be done another time.
* Renamed BFS_SHELL define to FS_SHELL, such that QueryParserUtils can be
used in any file system shell, not just the bfs_shell.

haiku_loader: Reuse BPlusTree implementation of the BFS add-on.

Instead of having an almost exact, albeit read only, duplicate of the
implementation.

Made it possible to build the bootloader when targetting x86_64.

* x86_64 is using the existing *_ia32 boot platforms.
* Special flags are required when compiling the loader to get GCC to compile
32-bit code. This adds a new set of rules for compiling boot code rather
than using the kernel rules, which compile using the necessary flags.
* Some x86_64 private headers have been stubbed by #include'ing the x86
versions. These will be replaced later.

* Removed the home-brewn locking classes in BFS besides the read/write lock
(for now).
* Inode::fSmallDataLock is now a recursive_lock, Journal::fLock is now
a recursive_lock, too, Journal::fEntriesLock is now a mutex, as is
BPlusTree::fIteratorLock.

Fix the build.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25397 a95241bf-73f2-0310-859d-f6bbb57e9c96

Fixed boot loader BFS build which I broke with my recent changes.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20861 a95241bf-73f2-0310-859d-f6bbb57e9c96

KernelAddon and KernelStaticLibrary don't include kernel, kernel arch, boot platform headers anymore.
Fixed the build of most of targets using these rules. Though the build can be still broken, feel free to fix.

This should fix the build after all the kernel/system renaming.
If anything is still broken (and was not before :)), please shout.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@12361 a95241bf-73f2-0310-859d-f6bbb57e9c96

Renamed src/kernel to src/system.
