21808e8f0b kernel: Limit maximum priority penalty
The maximum penalty the thread can receive is now limited depending on
the real thread priority. However, since it make it possible to starve
threads with priority lower than that limit. To prevent that threads
that have already earned the maximum penalty are periodically forced
to yield CPU to all other threads.

e083bca041 kernel: Allow threads to always finish their time slice
Until now, when the thread has been preempted by higher priority
thread it was then placed at the end of its priority FIFO and given
a new time slice. This patch changes it allowing the thread to
complete its time slice (when the higher priority threads are done),
unless there was very little time left in which case this time is added
to the next time slice.

Apart from making the algorithm more fair this change allows to identify
CPU bound threads more easily. (Earlier they could 'hide' by being
preempted by higher priority thread and consequently never using
their whole time slice).

82c26e1f1f kernel: Punish CPU bound threads
This patch appears to fix #8007.

Thread that consume its whole quantum has its priority reduced. The penalty
is cancelled when the thread voluntarily gives up CPU. Real-time threads
are not affected.

The problem of thread starvation is not solved completely. The worst case
latency is still unbounded (even in systems with bounded number of threads).
When a middle priority thread is constantly preempted by high priority
threads it would not earn the penalty, thus the lower priority threads
still can be starved. Moreover, the punishment is probably too aggressive
as it reduces priority of virtually all CPU bound threads to 1.

37343ca1f6 Remove which command from default image
* This was a script relying on a working /etc/profile, which may not be
there
 * Instead, use GNU which, available as an haikuport recipe
 * Since the command does not seem to be needed for Haiku to run (and
also because I don't know how to do it), GNU which isn't in the default
 install.
 * Typing "which" in a terminal still works, as that uses an alias
defined directly in /etc/profile.

7aecb0b276 kernel/util: Make exit() available in kernel mode
Since we are using libraries originally intendent for user mode in kernel
mode providing them with some userland functions is inevitable. This
particular patch is to make zlib happy and able to call exit() when
its debug assertions fails.

1238bebddc build: Add stub _get_thread_info() needed by support/Referenceable.cpp
This is a step towards fixing #10042.

When DEBUG is set BReferenceable::~BReferenceable() performs some checks
ensuring that the object is destroyed correctly. These checks require
information on thread stack, which is obtained by get_thread_info().

_get_thread_info() stub is added (actually, readded) which always returns
B_ERROR. Moreover, the check in BReferenceable destructor is modified
so that it does not fail when get_thread_info() fails.

88cd0fd25b HaikuDepot: improve progress tracking.
- PackageManager: Adjust progress listener interface to also supply
  the package name to the hook. Adjust implementors.

- PackageActions now get a pointer to the model. InstallPackageAction
  uses that to resolve the package name given in the download progress hook
  to the package currently being downloaded, and updates progress accordingly.
  Consequently, if one requests installation of a package that has dependencies,
  Depot now correctly updates the download progress status of those
  accordingly, rather than updating the original package repeatedly.

8bf87f9341 Actually fix the build
Looks like I was too quick on previous commit.

It seems -pthread is actually not that much needed on Linux though...
although the manpage says "compile and link with -pthread". Go figure.

Now dlopen() uses RTLD_LAZY | RTLD_LOCAL for Linux, which seems
to work here.

4135f9cde3 Fix build
Declare a HOST_PTHREAD_LINKFLAGS variable to hold the flags
required to link with pthreads, and use it for the solver addon.

Works on GNU/Linux, please test and fix for other platforms.
