Also do some cleanup in private headers, I can't imagine why the build
libraries would need this function.

My upcoming changes to use our "futexes" instead of semaphores
will obviously not work on non-Haiku platforms, so we now
need a copy of this class in libbe_build.
The sparc openboot implementation can run executables in the a.out
format. We used to generate these using objcopy, but this does not work
anymore as binutils is deprecating a.out format support.
- Import elf2aout from FreeBSD
- Add some missing bits to our elf.h and have a copy of it in the build
headers so it can be used to build elf2aout for the host platform
(tested for Linux)
- Use it to generate the sparc haiku_loader
- Adjust the bootloader linker script to have two "program headers": one
that is not loadable and contains the ELF headers, and the second one
that is loadable and contains the actual code and data. Unlike
objcopy, elf2aout relies only on the program headers to know what to
put in its output file (sections are ignored), so this is required
otherwise we end up with the ELF header nested inside the a.out file,
and everything offset from the expected load address as a result.
Confirmed that this allows to build the loader and run it as far as
before, so I'm back to needing to implement some MMU support now.

By default, all targets support the "haiku" platform, and we no longer
support building for BeOS, Dan0, Zeta, or other BeOS-compatible targets,
so this is no longer needed.
Also remove all references to the non-Haiku compatible platforms, and
change all BEOS_COMPATIBLE checks to HAIKU_COMPATIBLE. Removal of
all SetSubDirSupportedPlatformsBeOSCompatible invocations
will be in the next commit.
If this triggers, it means something is using the "build" errors while
the build system thinks it is not, which is always an error. Nothing
triggers this at present, but some subtle bugs in the build system
a while back would have been caught by this.
Use BStackOrHeapArray instead of using auto_ptr to array.

This doesn't fully work yet (the FS code in libroot_build
needs to be adapted, as some of the symlink-related calls
are not available on MinGW), but it gets much further than
the "Cygwin" target did.
These have been broken for a long time. Some Cygwin changes that
are relevant on MinGW are kept here, but users on Windows who
want to build Haiku should probably use WSL at this point.
However, now that we are using relative paths and don't need
to worry about drive path kludges, it's actually possible to
get some host tools built on MinGW. Changes for that coming.
This was done using macros before, which isn't the way we have things set up.
In theory that method should work, however if not all consumers include the
libroot_build headers properly, then it breaks in subtle but confusing ways,
which is not what we want at all.
Thanks to Jessica for advice.

John's revert of my removal commit dragged back a bunch of cygwin/sunos
cruft, as well as re-adding RegExp.cpp to the host libshared, that we don't
need.
Instead, remove this and add libgnuregex_build to just the tools/keymap
link alongside the FreeBSD gnuregex case.
As it turns out, using the xattr emulation layer plus "libgnu"
causes some strange mixups at package build time, and so packages
built with it were winding up with no attributes at all.
So I've just bitten the bullet and written a full passthrough layer
to the system attributes. Verified using a full build of haiku.hpkg
this time ... after a lot of painful debugging of symlink mixups.
Hopefully I am finally rid of this plague...
To quote jscipione (from 95e8362c52),
"Let me tell you a story about a bug" -- though this tale spans a much
lesser time than that one did.
In 5e19679ea3, I enabled libroot_build for
Haiku, instead of using the system libroot as we had before. There were
a number of bugs introduced along with this that I hadn't fixed (and there
may be more after this), but most of the obvious ones (crashes on x86_64...)
were fixed shortly enough.
Attribute usage, though, was a different story. Unlike most of the POSIX
calls in libroot, which were aliasing system functions no matter what the
platform, the attribute calls were not, as they are specific to Haiku.
Initially I had completely forgot about them, and it wasn't until a few days
later when I noticed that I had an "attributes" directory in my generated
that I realized that the "generic" attribute layer was being used on Haiku.
I attempted a fix for this in 5e19679ea3,
thinking that would clear the problem up, but I didn't actually run a test
beyond seeing that my BuildConfig had been updated properly. In fact,
BuildSetup was hard-wired to not even pass that definition through on
Haiku, and so that commit had in effect caused nothing.
My initial "fix" of just changing BuildSetup then caused a build failure,
as while libroot_build itself compiled, it ran into errors whenever attributes
were used, because in letting the real libroot's attribute calls shine
through, I had bypassed libroot_build's FD emulation/shim layer.
Then I tried and failed at three separate attempts to solve this with code:
- a version of the "fs_attr_...h" interface for Haiku. This proved possible
in theory, but in practice I would need to reimplement a lot of attribute
handling code in it, because all I had access to from there was syscalls.
- a version of "fs_attr_untyped" that bypassed its reimplementations of
the "fs*attr" functions for the libroot ones, only using the FD shim layer.
This proved possibly not even theoretically possible because it would have
caused preprocessor hell in some of the build headers, and also assumptions
about how attributes are read were totally different.
- a completely new "fs_attr_haiku" that was a completely new interface to
the fs*attr functions. This proved practically impossible because of the
need to include structures from the system libroot to call out to readdir,
etc. that attempts to solve would also have caused preprocessor hell.
Then I realized that the Linux xattr emulation library, which I'd used
as a reference when attempting the first solution, was shipped by default
as a system library in all builds of Haiku ... and so I could just tell
fs_attr_untyped to use the Linux xattr handler, and then link against libgnu.
So that is how I arrived at this strange and decidedly unorthodox solution
to a problem of my own creation.
It was needed on macOS for a time when BUrl used regexes for parsing.
Now it does not, and so we can remove libshared's RegExp from build
libshared, and thus also libgnuregex.
I didn't notice this in the previous commit because apparently GCC2
just links against libroot's versions of them. On GCC5, however,
the version from libroot_build was used even for calls from libroot itself,
which led to infinite loops and then stack overflows.
So instead we must have the "syscall" functions in libroot_build shadow
the real ones by being named differently, which I did by changing their
prefix from "_kern" to "_kernbuild" via preprocessor macros.
Since the build syscalls.h is now substantially different than the non-
build one (and has not been synchronized in nearly a decade anyway),
I've just stripped out all the syscall defns except for the ones actually used
in the build.
Thanks to kallisti5 for helping me debug and test.
Previously we just used the system libroot, which of course meant
that when libroot's ABI changed, the build broke. Now we use the full
libroot_build that we do on non-Haiku platforms. The logic for "BeOS-compatible
but not Haiku" does not really apply anymore, so it has been gutted where
appropriate (and libhaikucompat has been decoupled from the build.)
The only caveat here is the change to Errors.h -- we really should be using
the system's one where I included the one from the tree, but for whatever
reason, GCC2 refused to handle the #include_next properly.
Fixes the build breakage of Haiku-on-Haiku by my prior commits (sorry).
Technically a "hack" (but then again most of the config/build stuff is);
as we need to use the system's config/types.h in order to get stdint
definitions and the like.
Previously there was a config_build directory which allowed the existence
of two types.h -- the system one, and the headers/build one, but seeing
as we only need this to provide Haiku-specific core types on other platforms,
using the system's one should be fine.
Our core type definitions have not changed in some time (and it's unclear
when they would change aside from potential new platforms), breakage of the
Haiku-on-Haiku build due to this should not happen often (if ever.)
Now that we do not target BeOS and also do not include the main headers
directory when building "build" binaries, we can drop the separate
config_build directory and thus also the separate BeBuild.h, and just
..-include the regular one.
The build BeBuild.h defined empty _IMPEXP_ROOT and _IMPEXP_BE preprocessor
macros that the regular one does not; so I also re-synchronized
headers which used these as needed.
This file was apparenly based off the BeOS one (as is evidenced
by the "Be Incorporated" copyright ... which is problematic.)
Now it's directly based off of the non-build one.
Thus, BeOS compatibility is preserved (and there is no risk of
breaking GCC5<->GCC2 interoperation on hybrid builds.)
This commit only makes the actual change, the build fixes are
in the next commit.
* Fixes problems with setting the partition name after uninitializing
a partition in DriveSetup. Previously, UninitializeJob() was
followed by SetStringJob(), but the kernel was updating the
change counter for the parent partition when uninitializing a
partition, leading to SetStringJob() having an incorrect change
counter for the parent partition. Now the parent change counter
will be correct when SetStringJob() runs.
Apple has gotten around to updating their POSIX support so these
constants are now defined. Add some #ifndef guards to prevent warnings
during compile.
* Put it in the BSupportKit namespace, following the style introduced
with the package kit for now.
* The BSupportKit::BJob class no longer knows about the package kit's
Context class. However, the BPackageKit::BJob class does.
* Due to the namespace juggling, a lot of files had to be touched.
* The JobQueue class remains private.
* Due to the way Haiku is built on itself, you cannot build this change
under Haiku with an older release.
* When you receive a message from a KMessage, and reply to it,
it will automatically reply as KMessage, too.
* This allows to communicate with BLoopers from within the kernel
or libroot.so.
* So that you know how much already was, and still has to be downloaded.
* Automatic whitespace cleanup.
* The link in FetchFileJob.h did not fetch the correct header under
Haiku anymore (since the addition of the private headers to the
image).
This reverts commit 34dbbb65fd.
Instead, we can remove thos from HaikuBuildCompatibility and things will work fine, unless one try t build Haiku on BeOS (this isn't
supported anymore) or a very old Haiku which esdon't have those.
Simple BPositionIO implementation using the POSIX API on a FD. In effect
similar to BFile, but more easily ported to kernel and boot loader (and
the FD is reusable).
* BCompressionAlgorithm is a base class for classes that provide
compression/decompression functionality. There are methods for
compressing/decompressing a single buffer and factory methods for
a compressing/decompressing input/output BDataIO.
* BZlibCompressionAlgorithm is a BCompressionAlgorithm implementation
using zlib.
The only purpose of this was to use the installed version of Errors.h,
which isn't strictly needed and create some annoyance when new error
codes are added.
This allows adding new error codes to the libbe_build without breaking
the build on older Haiku versions.
Fixes the build for the newly introduced B_PARTIAL_READ and
B_PARTIAL_WRITE.
