* Added new(mynothrow) operators which avoid clashes when also linking
  against libgcc.

65a9d40a9d * Added hash_dump_table() function, dumping the whole table.
* Fixed hash_remove_current(): It didn't update "lastElement" and thus
  always also removed all elements in the same bucket preceding the one
  to be removed. Also got rid of the useless "for" loop.
  Fixes #2757.

dcadb2ba8d Patch by Zhao Shuai:
* Imported radix bitmap tree implementation from FreeBSD and adjusted it
  for Haiku.
* Make use of the radix tree in the swap support implementation instead
  of using simple bitmaps. This will allow for faster swap slot
  allocations. ATM Haiku doesn't benefit that much, since we always
  allocate single pages, but that will change eventually.

0b46f622d1 * Made struct ring_buffer public (within the kernel).
* Added "syslog" command that dumps the contents of the syslog ring buffer into
  KDL. Use the '-n' option to only show what hasn't been sent to the syslog
  daemon yet.
* When entering the kernel debugger, the current thread ID and name are also
  printed (not only the current CPU).

5c99d63970 Merged branch haiku/branches/developer/bonefish/vm into trunk. This
introduces the following relevant changes:
* VMCache:
  - Renamed vm_cache to VMCache, merged it with vm_store and made it a
    C++ class with virtual methods (replacing the store operations).
    Turned the different store implementations into subclasses.
  - Introduced MergeStore() callback, changed semantics of Commit().
  - Changed locking and referencing semantics. A reference can only be
    acquired/released with the cache locked. An unreferenced cache is
    deleted and a mergeable cache merged when it is unlocked. This
    removes the "busy" state of a cache and simplifies the page fault
    code.
* Added VMAnonymousCache, which will implement swap support (work by
  Zhao Shuai). It is not integrated and used yet, though.
* Enabled the mutex/recursive lock holder asserts.
* Fixed DoublyLinkedList::Swap().
* Generalized the low memory handler to a low resource handler. And made
  semaphores and reserved memory handled resources. Made
  vm_try_resource_memory() optionally wait (with timeout), and used that
  feature to reserve memory for areas.

* Added a KMessage::IsEmpty() method.

SplayTree, additionally maintaining a singly-linked list, thus allowing

  and returns an error, if that fails.

  InitCheck() methods in the network code by Init().

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.

8562499f44 * Introduced a new locking primitive I called "cutex" (sorry for the
name, couldn't resist :-P). It's semantically equivalent to a mutex,
  but doesn't need a semaphore (it uses thread blocking and a simple
  queue instead). Initialization can't fail. In fact it is ready to use
  without initialization when living in the bss segment, also in the
  early boot process. It's as fast as a benaphore in cases of low lock
  contention, and faster otherwise.  Only disadvantage is the higher
  immediate memory footprint of 16 bytes.
* Changed how the "thread" and "threads" debugger commands list the
  objects they are waiting for. Cutexes are also included.

801591dbde * Added an atomic_pointer_set() template function to util/atomic.h.
* Made the pointers const.
* Changed how the ARP module maintains its arp_entry::request_buffer: it
  now uses the atomic_pointer*() functions to make sure there is no race
  condition, and it's deleted only once.
* Getting an ARP entry would return uninitialized data, if the entry hadn't
  been resolved yet.

b1d749f8f1 * Added an atomic.h header that provides a C++ file with a templatized
64-bit safe version of atomic_test_and_set() for pointers:
  atomic_pointer_test_and_set().
* The VFS is now using this function (it's not used anywhere else in the
  kernel this way).

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.

c76695a275 * The C "struct list" and the C++ DoublyLinkedList implementations had mixed
next/prev link order - that messed up the DoublyLinkedListCLink adapter.
* Since it's more likely that someone messes with the C version, the C++ version
  now uses the same order than that one.
* This fixes a bug when TCP's BufferQueue tried to iterate over a list, messing
  up its integrity.

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.

  power of two is passed.

with the same size as the class is defined.

  in case of being told to initialize from the given buffer.
* Added handy Get*() methods returning a field element value or a
  supplied default value, if the field element doesn't exist.
* Added also handy Set*() methods setting the value of first element of
  a field, i.e. adding it, if it didn't exist before, otherwise
  replacing the old value. Only for fixed size types.
* Moved _FindType() inline template method into the header.
* Made the source file fit for use in the boot loader. If the macro
  KMESSAGE_CONTAINER_ONLY is defined, the message sending/receiving part
  is omitted.
