kernel & runtime_loader: Don't load from non-packaged when "Disable user
add-ons" is set.

Confirmed to fix #14361. It is finally possible to un-brick an install
with a bad system library in non-packaged without having to use another
install to do so.

runtime_loader: Fix handling of #!/usr/bin/* introduced in hrev53048

Code was comparing "/usr/bin/" with "/usr/bin/env" of whatever was
passed. We now only compare the substring.

# 2e95cfda 07-Apr-2019 Augustin Cavalier <waddlesplash@gmail.com>

runtime_loader: Remove the user paths from the initial/"fallback" set.

This set is only used until the SetupEnvironment script has run, i.e.
for launch_daemon and its initial tasks, which does not need the user
paths. Solves a TODO.


# 938d81f6 06-Apr-2019 Augustin Cavalier <waddlesplash@gmail.com>

runtime_loader: Rewrite all "/usr/bin/" shebangs to "/bin/".

Previously we only rewrote ones pointing to "env" with that.

build: Add initial ARM64 target.

It will probably be just stubs for the significant future, but,
here it is anyway.

Regarding the naming: Yes, the official name is "aarch64." However,
Linux, FreeBSD, and Zircon all call it "arm64", and so we will do the same.

I've configured it initially to be a Clang-only port, making no
changes to GCC buildtools whatsoever here. We'll see if that sticks,
however.


# 2aaad308 02-May-2018 Jérôme Duval <jerome.duval@gmail.com>

runtime_loader: enable elf32 on x86_64, elf64 on x86.

use x86 as default sSearchPathSubDir in compatibility mode.
use the generic memset/memcpy when x86_64 is the primary arch.

elf.h: rename ELF_MAGIC to ELFMAG

- This is how it is named in other versions of elf.h (Linux, glibc, possibly more)
- ELF_MAGIC is used by libelf for the same thing, and the defines conflicts,
breaking libelf build on Haiku.

runtime_loader: only add ABI directories to system library paths

It only makes sense to add the ABI directories to library paths
created by Haiku itself. E.g. on a gcc2h build, appending x86.

This also fixes build issues where LIBRARY_PATH is amended, and
the target binaries and libraries are in different locations.

Note: the develop lib directories were excluded, as runtime_loader
shouldn't be looking at these in the first place.


# 9fc69d1b 12-Jan-2014 Jonathan Schleifer <js@webkeks.org>

runtime_loader: Add __dso_handle.

The symbol is needed for global objects. Usually, GCC also requires
this, but for some reason, the linking error only occurs when using
Clang.

runtime_loader: Detect and trigger on PE binaries

* Previously PE binaries would trigger the "incorrectly
executable" dialog. Now we get a special message for
B_LEGACY_EXECUTABLE and B_UNKNOWN_EXECUTABLE
* Legacy at the moment is a R3 x86 PE binary. This could
be extended to gcc2 binaries someday far, far, down the
road though
* The check for legacy is based on a PE flag I see
set on every R3 binary (that isn't set on dos ones)
* Unknown is something we know *is* an executable, but
can't do anything with (such as an MSDOS or Windows
application)
* No performance drops as we do the PE scan last
* Tested on x86 and x86_gcc2


# 8d23c440 26-Nov-2013 Ingo Weinhold <ingo_weinhold@gmx.de>

runtime loader: Add support for $ORIGIN in rpath

# 38fa81bf 03-Oct-2013 Ingo Weinhold <ingo_weinhold@gmx.de>

Remove B_COMMON*_DIRECTORY and kCommon*Directory constants

* This does intentionally break source compatibility, so that a review
of concerned code is forced.
* Binary compatibility should be maintained in most cases. The values
of the constants for the writable directories are now used for the
writable system directories. The values for the non-writable
directories are mapped to "/boot/system/data/empty/...", an empty or
non-existent directory, so that they will simply be skipped in search
paths. Only code that explicitly expects to find something in a
B_COMMON_* directory, will fail.


# 729c6333 05-Jun-2013 Oliver Tappe <zooey@hirschkaefer.de>

Runtime loader: don't fall back to OS-ABI directories.

* when an executable with a different ABI is being loaded and some
needed image isn't found, don't retry using the standard ABI folders
of the system - those are now considered incompatible


# e85e399f 17-Mar-2013 Pawel Dziepak <pdziepak@quarnos.org>

commpage: randomize position of commpage

This patch introduces randomization of commpage position. From now on commpage
table contains offsets from begining to of the commpage to the particular
commpage entry. Similary addresses of symbols in ELF memory image "commpage"
are just offsets from the begining of the commpage.

This patch also updates KDL so that commpage entries are recognized and shown
correctly in stack trace. An update of Debugger is yet to be done.


# e3ac2588 25-Jul-2012 Alex Smith <alex@alex-smith.me.uk>

Changed runtime_loader to use elf_* typedefs over Elf32_*.

This means that it will be using ELF64 types on x86_64 rather than
ELF32. The next step for supporting x86_64 is to implement relocations.


# 323b6546 21-Nov-2011 Oliver Tappe <zooey@hirschkaefer.de>

Filtered flat import of Oliver's svn package management branch

Bring the changes that aren't package management related and the ones
that are but don't take effect as long as they are ignored by the build
system into the master.

Summary of changes:
* Introduce private header <directories.h> with constants for a good
deal of paths that should usually be retrieved via find_directory().
* Replace hard-coded paths by using find_directory() or the
<directories.h> constants (e.g. in drivers and the kernel).
* Add find_directory() constants needed for package management.
* Add __HAIKU_ABI_NAME and B_HAIKU_ABI_NAME macros.
* src/apps/deskbar: BeMenu.* -> DeskbarMenu.*,
DeskBarUtils.* -> DeskbarUtils.*
* Change deskbar menu settings directory from ~/config/be to
~/config/settings/deskbar.
* Other smaller cleanups, changes, and fixes.
