This patch introduces support of ELF based TLS handling with lazy allocation
and initalization of TLS block for each DSO and thread. The implementation
generally follows the official ABI except that generation counter in dtv
is in fact a pointer to Generation object that contains both generation
counter and size of the dtv. That simplified the implementation a bit, but
could be changed later. The ABI requirements regariding in memory position
of TLS block is not honoured what results in static TLS model being
unsupported. However, that should not be a problem as long as
"executables" in Haiku are in fact shared objects and optimizations which
require specific TLS block in memory layout are not possible anyway.
With some testing, found that even with the second patch
provided in #10792, the behaviour is still inconsistent, so
reverting for now.
This reverts commit 273109e004.
* Linux is the only one of our supported build hosts to not have
mergesort. Provide an implementation that calls qsort, since the qsort
implementation in the glibc used by Linux uses a mergesort (!) for small
arrays.
* Use merge sort, which is a stable sort, instead of the qsort used in
BList::SortItems
* This allows setting two stops with the same offset to create a sharp
color change in a gradient. This trick is used to create stripe patterns
with css gradients in some web pages.
Fixes#10733.
* Adjust the respective rules such that with disabled downloads, only
packages already available in the downloads folder will be considered
as available build features.
This way, the build system will not for instance try to build
<kdebug>qrencode after a bootstrap, as that package is not yet
available.
When a system package is going to be deactivated, activate/deactivate
the packages of the whole transaction only to the latest state.
Afterward latest state and active state will differ.
* VolumeState: Move locking to Volume.
* Package: Pull the file related functionality into new class
PackageFile. A Package refers to a PackageFile. A PackageFile can be
referenced by multiple Packages. PackageFiles are managed by the new
PackageFileManager.
* CommitTransactionHandler: Clone the passed volume state.
* Volume now manages two VolumeStates: A state reflecting the currently
active packages and the latest state (i.e. the one reflecting the
situation of the packages directory). Usually the two are the same,
unless an old state has been booted.
* The client interface hasn't been adjusted yet. Clients only see the
latest state.
* If --no-downloads has been given, Haiku will be built without
trying to download anything, all required packages need to be put
into the download folder manually (the build will stop on missing
packages).
* As the required HaikuPorts repository can't be downloaded in this
mode, a local repository is created during the build, which only
contains the packages available in the downloads folder.
This is useful for building Haiku completely from source.
* The content of the preprocessed package-info files and the package
contents depend on the build type, so we use a different folder for
each build type.
* Nothing ever reads fTargetName in the scrollbar code, so remove the
field.
* Frees one reserved slot, and a little memory, as the target name was
copied with strdup.
* The ptrdiff_t limits are PTRDIFF_MIN and PTRDIFF_MAX, not PTDIFF_*.
* I could not find any non-Haiku reference to PTDIFF_*, so I guess
that's a mistake.
* Add info on Allwinner A10 SOCs, which may be a worthwile target.
* Add info about the Linaro QEmu for emulating the BeagleBoard.
* Add more TODOs for PM aftermath.
* This is enabled by shift+click on the Original Size toolbar button.
* The button stays pressed as long as the feature is enabled. Clicking
it again disables it.
* When this is enabled, all images will be shown at original size,
instead of being scaled up or down to fit the window.
* This is not persistent, and only affects the current session/window.
* BIconButton is not needed anymore, now that BButton supports icons.
* Slight look changes. These buttons are a bit bigger, with extra
whitespace. I compensated this by reducing the insets and spacing, which
looks the same when no button is hovered, but a bit different when one
is, as the button frame is bigger. Maybe we need to tweak BButton to
have smaller margins like BIconButton did.
* Don't intercept Enter key press in a window when there is default
button and another BControl focused.
* Current behavior was basically breaking every window using default
button. Even if there was a button focused (using Tab key), when Enter
was hit, default button handled the message, therefore instead of
i.e. 'Revert' 'Apply' was pressed.
* Fixes#10792.

* Fix the condition so that big images are fitted to the window on first
time only if the option is set.
* Small images are never stretched to the window size, as this isn't
very useful.
The interaction of this global setting with the zoom buttons is a bit
confusing. Should they be merged?
