0c615a01ae * Removed old mutex implementation and renamed cutex to mutex.
* Trivial adjustments of code using mutexes. Mostly removing the
  mutex_init() return value check.
* Added mutex_lock_threads_locked(), which is called with the threads
  spinlock being held. The spinlock is released while waiting, of
  course. This function is useful in cases where the existence of the
  mutex object is ensured by holding the threads spinlock.
* Changed the two instances in the VFS code where an IO context of
  another team needs to be locked to use mutex_lock_threads_locked().
  Before it required a semaphore-based mutex implementation.

4a67038e56 * Added a new function hash_insert_grow() that grows the hash table when needed.
* Removed the public hash_grow() function again (at least for now, it's only
  private).
* Removed the newSize argument from hash_grow(); it will compute the new size
  automatically.
* The block cache is now using hash_insert_grow() instead of hash_insert()
  which should make hash lookups much faster with some 10 thousand blocks,
  also increased the initial table size from 32 to 1024...

dfa4dfe033 Something else that has been laying around for some time. Implemented hash_grow() that can grow a hash table to a new table size. Automatic growing is commented out in hash_insert() since there needs to be a way to disallow growing in certain cases (i.e. where no allocations can be made). This is detailed in the ToDo at the top of the file.

e6dc7903e4 * vm.h no longer includes vm_types.h - only those that actually need access
to the private VM types are including vm_types.h now.
* Removed vm_page, vm_area, vm_cache, and vm_address_space typedefs; it's
  cleaner this way, and the actual types are only used in C++ files now,
  anyway.
* And that caused changes in many files...
* Made commpage.h self-containing.
* Minor cleanup.

40c3aedf8d * Added hash_count_elements() and hash_count_used_slots() (mainly for
diagnostic purposes).
* hash_init() adjusts the table size to a prime number, which should
  result in a better element distribution, particularly since usually a
  power of two is passed.

2529455101 Revised the AVLTreeMap code:
* Pulled the actual tree code into a non-templatized class AVLTree to
  reduce the amount of code generated each time the template is
  instantiated.
* Changed the iterator interface to Java-style.

74c0424a43 * Added a mechanism to retrieve a BMessage with eventual error descriptions
for _kern_load_image().
* Added KMessage to the runtime_loader (a bit hacky, though) - it will use
  it to deliver the above mentioned functionality.
* load_dependencies() did return the wrong status code in case a library
  was missing; now it returns B_MISSING_LIBRARY.
* load_dependencies() will now try to load all dependencies when a report
  message is requested; therefore, all missing libraries are listed.
* Renamed uspace_program_args to user_space_program_args.
* The kernel filled in various members of the user_space_program_args structure
  unsafely, ie. was not using user_memcpy().
* Renamed some local variables in team.c to better fit our style guide (ie.
  uargs to userArgs).
* Changed Tracker to use the new _kern_load_image() variant on Haiku to retrieve
  and report all missing libraries. This fixes bug #1324.
* Adapted kernel_cpp.cpp to the runtime loader as well; the latter will now
  compile with _LOADER_MODE defined.

02cc779b7d Moved datastore implementation into net_buffer.cpp - there is no reason to clobber the kernel with it.
This also fixes the issue of exporting a C++ API from the kernel.

957a1b17eb * Introduced new build system variables
{HAIKU,HOST,TARGET}_KERNEL_PIC_{CC,LINK}FLAGS which define the
  compiler/linker flags specifying the kind of position independence
  the kernel shall have. For x86 we had and still have -fno-pic, but the
  PPC kernel has -fPIE (position independent executable) now, as we
  need to relocate it.
* The boot loader relocates the kernel now. Mostly copied the relocation
  code from the kernel ELF loader. Almost completely rewrote the PPC
  specific relocation code, though. It's more correct and more complete now
  (some things are still missing though).
* Added boot platform awareness to the kernel. Moved the generic
  Open Firmware code (openfirmware.c/h) from the boot loader to the kernel.
* The kernel PPC serial debug output is sent to the console for the time
  being.
* The PPC boot loader counts the CPUs now and allocates the kernel stacks
  (made OF device iteration a bit more flexible on the way -- the search
  can be restricted to subtree). Furthermore we really enter the kernel...
  (Yay! :-) ... and crash in the first dprintf() (in the atomic_set()
  called by acquire_spinlock()). kprintf() works, though.

aeef8a1098 Reverted to the previous version. I was too quick; the boot loader
doesn't link against libsupc++ and still needs the symbol.

758b1d0e05 Fixes that make Haiku build with gcc 4. Mainly out of the following
categories:
* Missing includes (like <stdlib.h> and <string.h>).
* Linking against $(TARGET_LIBSTDC++) instead of libstdc++.r4.so.
* Local variables shadowing parameters.
* Default parameters in function definitions (as opposed to function
  declarations).
* All C++ stuff (nothrow, map, set, vector, min, max,...) must be imported
  explicitly from the std:: namespace now.
* "new (sometype)[...]" must read "new sometype[...]", even if sometype is
  something like "const char *".
* __FUNCTION__ is no longer a string literal (but a string expression), i.e.
  'printf(__FUNCTION__ ": ...\n")' is invalid code.
* A type cast results in a non-lvalue. E.g. "(char *)buffer += bytes"
  is an invalid expression.
* "friend class SomeClass" only works when SomeClass is known before.
  Otherwise the an inner class with that name is considered as friend.
  gcc 4 is much pickier about scopes.
* gcc 4 is generally stricter with respect to type conversions in C.
